Theories of Planned Behaviour

Fjbisset — Thu, 29 Oct 2009 16:22:14 +0000

Thanks to Andy Polaine for sharing this tremendous insight in response to my post yesterday. It’s fair to say that those students studying Service Design at Luzern are in great hands.

In his comments he wrapped up a lot of the wider tensions within the Service Design community about the relationship between academia and practice that I know are hot topics of discussion at London events such as Service Design drinks and Service Design thinks at the moment, as well as clearly the Service Design Network Conference held this week.

Indeed, a lot of the background to this post and my own work is fuelled by an urge to bridge some of this tension – between theory and practice as Andy put it – this is synthesis in the truest sense of the word.

For anyone interested further background to these issues can be found here and here.

If I created a strawman yesterday in my discussion of what was said at the Service Design Conference then I apologise. I suppose the essence of what I was attempting to highlight was that despite any personal philosophical or pragmatic differences of opinion that might exist within the community, there appears to be two prevalent ways in which designers classify users. One is to see users as reactive i.e. responsive to extrinsic constraints and the other is to see them as proactive i.e. energised by internal ideas and ambitions (goal oriented).

The reality seems to be that we as humans fluctuate between these states probably faster than we’ll ever be able to measure or generalise accurately (its not going to stop me trying ) and thus we as Service Designers rely on the ethnographic approaches Andy mentions or laboratory based scientific experiments that are well documented in scientific journals to attempt to understand behaviour.

Whether designers are fully concious of the fact that they are making these judgements about users is another issue open to debate and discussion. Indeed, the oft cited definition of Design Research is “to make explicit what is otherwise implicit in the everyday practice of design.” Thus by raising this discussion, I was simply attempting to raise this question within the minds of us designers about how we implicitly view the user we are designing for? As I mention above the answer appears to be as either ‘passive’ or ‘active’ depending on circumstance, context or which particular part of the design or use phase we might be referring to.

Education systems are interesting service examples themselves in how they attempt to balance between encouraging creativity and intrinsically motivated behaviour whilst also controlling these processes with structured curriculum and routines. Indeed, any service we can think of will attempt to strike a balance between generating and controlling value (or creativity, or energy, or money) for all the stakeholders involved.

As Andy clarified in his comment on the last post, Birgit Mager was talking at the Service Design Network Conference about users behaviour being a function of Attitude and The Environment. On further research this would appear to also share perspective with that of the Theory of Planned Behaviour (Ajzen, 1988) which is also based on Theory of Reasoned Action (Ajzen and Fishbein, 1980).

This classifies user behaviour as a product of:

Attitude (Autonomy)
Social Pressure (Relatedness)
Perceived Behavioural Control (Competence)

What I’m interested in as part of my masters is how we can design systems and services that enhance user perception of these three inherent human psychological capabilities. Doing so successfully or even unsuccessfully will result in behavioural change, but doing so successfully and encouraging users to reflect on these capabilities will result in sustainable behavioural change (at least that’s the theory).

I’m incredibly fortunate that through this platform and as a result of contributions such as Andy’s I can also modify my own attitude and perceived competence as a result of being able to relate my work to you all.

Andy is right though we need to do more to work together and bridge the gaps between academia and professional practice. I don’t plan to stay in academia forever but whilst I’m still here I’d be interested to hear from you all… do you have any questions about Motivation? Is there something that you as a practitioner are working on and feel like you could use a bit of academic insight or research on?

What Are User Needs?

Fjbisset — Sat, 26 Sep 2009 22:38:56 +0000

My research around the past couple of posts on participatory processes and the responses they have generated have helped focus my attention on an issue that has interested me for some time – the question of “User Needs”.

Tim Brown on Change By Design from IDEO on Vimeo.

As the above video nicely represents, many of the early proponents or more successful marketers of ‘design thinking’ have often backhandedly justified the core value that ‘design thinking’ represents in terms of how it better fulfils ‘user needs’. Or at their most honest like in the video above (around 1min in), justified design thinking as the process of converting ‘needs’ to ‘demands’.

In reading and writing about Design, I can’t help but stumble across the term ‘user needs’, without ever finding a particularly compelling definition of what it is in any given context, let alone independent of context.

Having seen that horrible video above a few weeks ago and blown off a bit of steam on Wenovski about it at the time – I couldn’t help but be reminded of it when I read this rather cynical, but actually quite apt historical review of the term ‘user needs’ in a psychology paper today:

“A need is a construct (a convenient fiction or hypothetical concept) that stands for a force (the physico-chemical nature of which is unknown) in the brain region, a force that organizes perception, apperception, intellection, conation and action in such a way as to transform in a certain direction an existing, unsatisfying situation.” (Murray, 1938, pp. 123–124 in Deci and Ryan, 2000).

Aneed is a construct (a convenient fiction or hypothetical

concept) that stands for a force (the physico-chemical

nature of which is unknown) in the brain region, a

force that organizes perception, apperception,

intellection, conation and action in such a way as to

transform in a certain direction an existing, unsatisfying

situation. (pp. 123–124).

As a designer who over the past few years has done quite a bit of rummaging around in psychology books and papers, perhaps with a view to fulfilling some of my own user needs and requirements!? The issue of ‘needs’ whether psychological or physiological is a term that again crops up quite a lot. I’ve long personally held the suspicion that the designerly version of “user needs” was somehow different from the social scientist’s. However, if Murray as cited above is to be believed the term may be used as indiscriminately and cynically in psychology circles as it seems in design circles.

I’m not for a minute disputing that user needs are a real and important driver of both the work of designers and psychologists alike. I wholeheartedly believe that there are designers out there who strive to cater for genuine user needs and requirements. But if so what are they? Do we have a consistent definition amongst us that isn’t just a justification for making things in a way that people will want to buy them?

Is the whole concept of user needs a smokescreen behind which designers just do whatever they want and take your money in the process?

I’d really like to hear your thoughts on this so please either tweet them to me @fergusbisset or use the comments box below to let me know what you think. It’ll really help my Masters research into Motivational Design and judging by the video above it might even help our integrity as a community.

Designers as Coaches

Fjbisset — Sun, 09 Aug 2009 14:20:54 +0000

In response to my last post, Jonathan Baldwin asked the following question:

The idea of designers who are interested in the ideas rather than the finished artefact raises interesting pedagogical issues. How are they encouraged and rewarded in current educational environments?

His own thoughts can be seen in the comments page and ask some probing questions of the way that design is currently taught and communicated. My own answer to this question is central to my current MPhil research and indeed current day job. Thus I’ve reposted and rephrased some of what I wrote by way of response. Having had my annual review this week it fits in quite nicely with an update on some of my latest thinking. Any feedback, correction or diversions much appreciated!

As a designer who evolved to be a ‘design thinker’ as much as a ‘design doer’ largely as a result of my parallel life as a ski racer and professional (yes honestly, professional) ski instructor, the issue Jonathan highlights is one of big personal interest to me.

The problem occurs I think in that education seems rather quick to push or support people people into either ‘doer’ or ‘thinker’ camp. Doers, learn CAD and workshop skills, manufacturing processes and off they go resigning themselves to never seeing an end user again. I jest, but purely to make my point!

Holistic thinkers, in my experience undernourished in many ‘product’ or ‘graphic’ courses procrastinate in the face of unfulfilling practical assignments or labour and over intellectualise their more fulfilling graphic and research/ethonographic oriented projects.

Either way both hop from lily pad to lily pad of academic requirements without necessarily reflecting on why or whether their current task is serving some wider (social or personal) goal.

Often sold the idea that coming to university will guarantee them employment (and worse) that they deserve such employment by default and based on their perceived rather than actual skills and skillsets, the education system generally doesn’t seem to be good at opening us up to genuine self reflection.

That is self-reflection that occurs as a result of thinking you are good enough to win a competition and then finding out that actually you are not. Education as I see it should expose students to these real and yes sometimes brutal challenges, guiding them not towards ‘explicit solutions’ but rather the tools and mindset to reflect upon and redesign their approach. It is certainly something that any junior designer will experience as soon as they start working in the real world, or particularly at present, trying to find employment in the real world. For more on the ‘dark side of design’ see this post.

The parallel here, is the professional athlete (or serious amateur) for whom life is one big systematic and seriously demanding long term process. A process punctuated by a series of competitions (or perhaps design briefs) in which they have the chance to evaluate their performance against a set of defined rules or criteria. If they are successful there might be some prize money, a car or a free trip to Madeira. If they are not they instead go away with valuable feedback on their performance.

Educators and Designers should (from my perspective and as I am currently outlining in my my masters studies) be the coaches in this analogy. Helping and supporting the learners and users to reflect and re-evaluate their behaviour against long term behavioural, ecological, social and basic needs fulfilment. Providing them with proven tools and methods and analysing and experimenting with new innovative methods where appropriate to incrementally push the boundaries.

If I wanted to employ someone, I wouldn’t want to see their portfolio so much as I would want to see their ‘training plan’ and performance objectives for the duration of their employment (or study) with me. At present this seems to be something that only happens at a post-graduate or in research based education in this and to my knowledge any other country.

Such a strategic, performance oriented view would in my opinion also help overcome the whole Black Swan / ego / genius design problem of assuming that an individual’s past success guarantees future performance. Instead, allowing individuals to stagger their satisfaction and intrinsic reward for their pursuits in a much more incremental and balanced manner.

Competitive Anxiety – Are Service Design Competitions a Paradox?

Fjbisset — Fri, 07 Aug 2009 14:55:05 +0000

This weeks call to boycott the Service Design Network’s (SDN) recently announced competition and general grumblings within the service design community provide a fascinating insight into what makes service designers tick (and seemingly what doesn’t).

Rybinsk 2007 Podium - Photo: Pete Vordenberg - www.teamtoday.org

My initial reaction can be seen in the comments section in that last link, for the most part I am a little disappointed at the near unamimous and public way this competition appears to have been rejected by those who otherwise do so much to promote and positively communicate Service Design here in the UK and around the world.

What is it about this competition I wonder, and it seems competitions in general, that these service designers are opposed to? And from my perspective how much might service designers be distancing themselves from huge numbers of the population and public they claim to represent should they reject such ideas?

Jeff Howard and Jonathan Baldwin impressively and compellingly argue in the comments of that last post that such competive structure does not support the co-design process that is such a fundamental part of service design. But another post yesterday from Joel Bailey got me thinking perhaps its a bit deeper than that. Perhaps the very people (whether male or female as Joel contends) who are attracted to Service Design and it’s processes are those that generally speaking might not relish the idea of a competition.

Carol Dweck (2000) talks about Entity and Incremental ‘implict theories’. In otherwords, two distinct ways in which people percieve the world. There are those that believe that knowledge (or design) are static or intellectual entities and constructs. These constructs can be communicated by linear processes and static hierarchical diagrams. These would be ‘Entity‘ oriented individuals, who to generalise, are those more likely to prefer dealing in physical entities. In the case of design this would be the more traditional graphic or product ‘physically’ oriented design approaches.

According to Dweck the other sort of individuals consider Knowledge (and design) to be more fluid and incrementally elaborated and constructed, more open to debate and interpretation. These individuals are more likely to be interested in the process of design than they are in the final outcomes or physical representations of the design process. This is perhaps because they understand that these physical entities are fleeting representations or put another way simply the tip of the iceberg in the design process. I know for a fact I fall into this category, although I still see and have personally experienced huge value from participating in competitions and dealing and manufacturing in physical entities and constructs.

I don’t know about you, but I know which category I would place service designers (and systems thinkers) in. The latter Incremental category and this leads me to another difference that Dweck highlights, the difference in how these two individuals approach to challenges.

According to Dweck Entity Theorists relish competition, whilst Incremental Theorists (Service Designers) prefer collaboration. Dweck in fact places these two on a sliding scale – indicating that by her perception the two ideals are polar opposites. Perhaps, there are also correlations between males and females as to which gender is more likely to fall in which category. Personally I don’t see gender based distinctions as valuable and find Dweck’s a far more useful categorisation of characteristics of those by my interpretation more likely to engage with Service Design and it’s methods.

How are you being competitive? - Photo: Pete Vordenberg - Teamtoday.org

The one concern however that this insight highlights, and it echos my reservations about Service Designers seemingly being so quick to dismiss this competition this week is, that whilst Service Designers might be Incremental Thinkers and theorists I would bet the vast majority of the population at least in the ‘old world’ are not. This would explain why so many of us participate in competitive sport and value physical objects. Thus, whilst Jeff would still maintain that the service design community should not support this competition. I would encourage the community to do so, as a chance to better understand and resolve the challenges involved and of which we are all aware in communicating Service Design to those with different (Explicit) ideals and perspectives. After all, is holistic and flexible thinking not truely the purpose of co-design and the value that service designers are capable of offering?

Making Design a Concrete Experience

Fjbisset — Mon, 13 Jul 2009 00:58:59 +0000

“Design uses the whole person’s mind & body…”

This as I interpret it in my own recent contribution to the ‘Design Thinking debate is framing Design from a situated-cognition perspective. Again, saying that the activity of Design is inherently bound to it’s context of activity and therefore it is impossible to completely rely on empirical definitions of what design is or how to practice it. This is a controversial statement and one that can undoubtedly take a bit of time to come to terms with. I’d like to briefly use this post to elaborate how this idea has evolved in my mind and through my recent research into skill acquisition – as such it can be considered the full fat version of my previous post. It contains about 700 words and will therefore take about four minutes to read.

Concrete courtesy of Katorisi and Wikimedia Commons

‘Design Thinking’ of the sort discussed in the past months online debate and that first brought to our collective attention by IDEO represents “a community of practice” that is to say a socially mediated or mutually agreed definition of what design thinking is and how design thinkers should practice it. IDEO has very successfully wielded old media and more recently new media savvy to leverage it’s definition upon the world, thus increasing the awareness or ‘social definition’ or it’s Design Thinking ‘community of practice’. IDEO has done this so successfully in fact that like so many successful communities of practice the term ‘Design Thinking’ has become hugely widespread in its usage and definition, with the fringes of the community taking this definition and it’s processes and bending and moulding them to suit there own purposes and requirements. ‘Design Thinking’ has thus developed ‘social capital’ in terms of it’s ability to describe the tacit knowledge and processes of designers. A term that many people within the design and now business community understand and possess their own definition of.

What is clear however, is that the broader that ‘community of practice’ has become so to has the definition of ‘Design Thinking’. As I argued in my previous post it is now such a broad term that it is being rejected by aspects of the community it is supposed to represent. Indeed, judging by the comments to Collopy’s article it is being rejected by a large proportion of the design community, particularly those at fringes of the established design community in the evolving service design industry who are seeking at present to develop their own ‘community of practice’ and distinguish it from what has gone before.

The term ‘design thinking’ is not concrete. It therefore only exists as a social construct and it’s application is entirely dependent upon, influenced by and subject to its context.

This week I want to look at how then to develop ‘social capital’? Or more specifically how to teach or engage others with the essence or definition of what it is that you do as a service designer? How you become an Expert Design Thinker or Service Designer without an agreed definition of what that actually entails? More importantly, even if you or the institution that educates or employs you possesses such a definition, how do you communicate this to the rest of the world in terms that are meaningful and valuable to them? How do you interact with their “communities of practice”?

This is what might be referred to as establishing Legitimate Peripheral Participation, a process of individuals in this case entering the ‘design thinkers’ or ‘service design’ community and developing their skill gradually over time so as to become experts in the domain. In the terms of my recent research in Skill Acquisition and Public Engagement, this can be described as the transition from abstract observer to concrete experience. This process is perhaps better known as experiential learning.

I’m aware of a number of initiatives or individuals working on projects that are simultaneously attempting to develop ways of guiding people through this process towards concrete experience and education of ‘service design’ or design in general, I highlighted Participle’s Loops Initiative and Small Fish already. In the next few posts I plan to elaborate my own thoughts on how using the whole body and mind is key to developing ‘concrete experiences’ and key to successful engagement.

Fabricant Should Be Aware – Persuasion Requires More Belief and Less Judgement

Fjbisset — Fri, 03 Jul 2009 22:56:13 +0000

I’ve been mulling over Robert Fabricant’s ‘Ethnographic Defense’ post from the beginning of the week. Mulling because when I first read it I got quite worked up and decided to leave it until I’d calmed down a bit. I’ve just now (via @fredcollopy) seen another eerly similar article by Fabricant on Core77 and felt I had to respond on behalf all designers who believe in empowering rather than diminishing their users:

Fabricant closes his discussion on the ethics of Persuasive Design and User Centred Design with the following statement:

“users are not very self-aware. Shouldn’t designers be?”

The article serves as a discussion of how some of the currently employed or mooted Persuasive Design techniques might be considered by users to be “contrived or manipulating”. If I’m being honest, there’s not much more contrived or manipulative than his closing statement in the article, I’ll repeat it again:

“users are not very self-aware. Shouldn’t designers be?”

Hardly a statement likely to breed trust confidence or satisfaction in the design profession by their clients and consumers. Coming a few day’s after I’d read this article by Kicker’s Jen Bove summarising this presentation which also addressed the issue of ‘user needs’. I’ve been struck by the conflicting views of designers in their assessment of user needs and the best ways to repond to them.

There appear to be those designers who view their users as helpless ‘pinballs‘ (thanks Dan!) or those who have belief and trust in their users and wait for it…might even be prepared to involve and empower them in the design process. To clarify it seems Fabricant is positioning himself as only willing to engage with users if as a design professional he maintains a superiority or controlling influence. Whilst Bove in her talk seems more content by empowering her users through co-design and collaboration and admits rightly that as a designer she “has more questions than answers”.

I discussed some of these same ideas in my last post here about user’s expectancy for success – as my current research into designing motivationally engaging experiences demonstrates – the first step to engaging with your users is by making them aware of whatever new technology you want them to use. Thus, in a Motivational Design approach encouraging Awareness is the first responsibility of a designer. Making this new pattern of behaviour or technology relevant involves understanding not what user’s need, but rather how they learn and adapt to new situations and circumstances – their skill acquisition process. As a designer it is fundamental that you believe that your users are capable of and you empower them for behavioural change otherwise you, the designer and facilitator of their new behaviour or experience, are damned from the start by damning them.

The challenge as I see it for designers is being content to play a secondary supportive or coaching role in the process of persuasive design “Encouragement” as Albert Bandura might refer to it. Too often it seems that designers are more intent on pushing their own “genius of insight or perception” or the latest “cool technology” as opposed to truely recognising and supporting what users need or the best way to engage with them.

Industrial Design may have evolved from a Bauhaus ideology of making things aesthetically pleasing so that users felt inclined to purchase them over less attractive products and I concede it may have done so with some success, evolving to the point where designers are polished and capable enough to address more than simply a user’s perceived aesthetic need but also more recently their percieved emotional and social needs as well.

This as I discuss towards the end of this previous post has lead to a sitution where designers are declaring as Fabricant does in his Core 77 article this week:

What if the ‘users’ themselves are the problem? What if users represent not a coherent set of needs but a messy mix of desires and influences?

From where I’m standing it’s actually designer’s messy mix of desires, influences and egos that are the problem. Through the work on my Masters on Motivational Design and Public Engagement I plan to share with you an alternate approach to Persuasive Design, one that believes in supporting a user’s confidence and skill acquisition process, not diminishing it.

Design for Regime Change ¦ Expectancy for success?

Fjbisset — Wed, 24 Jun 2009 12:18:35 +0000

Our ATTENTION to and RELEVANCE of a message, determine people’s perceptions of its VALUE whilst an individual’s CONFIDENCE will determine their expectancy for success and their perceptions of CONTROL and SATISFACTION.

Whilst the emotionally charged sharing of news and updates is critical for raising AWARENESS or generating ATTENTION amongst potential supporters, in order to induce motivated behaviour parallel strategies need to be introduced to support both those sending the messages and guiding the individuals responses towards a specific short or long term goal. In it’s simplest manifestation this could include feedback on the number of times a particular piece of news has been linked to / read / retweeted, thus through feedback, motivating users that their voice is being heard.

Indeed, this has had a more literal and physical manifestation in the recent Iranian situation as this haunting and beautiful video demonstrates:

Shouting at the Sky

Such feedback is hugely valuable in combatting feelings of frustration or at their most extreme a feeling of learned helplessness – which is to say the sentiment that “nothing I do is ever going to make a difference.” But in this situation this is not didactic feedback from ‘a system’ to the user. The system in question here both online and offline are ‘social’ and enable users themselves to feedback to, inform and support each other. As Arne Oosterom elegantly put it a week or so back:

@designthinkers: “service designers should provide people with tools to self-organize around a common interest.”

How far can we as designers design in features that combat learned helplessness? As Nick Marsh highlighted yesterday in reference to this article;

@choosenick: ”People don’t think like the state: “I don’t have ‘needs’, I have something to give.”

Again there are a number of strategies for designers addressing ‘learned helplessness’, something that might also be referred to as demotivated behaviour. How many of these can be wrapped up by changing your focus to design dialectic as opposed to didactic systems.

Design for Regime Change

Fjbisset — Mon, 22 Jun 2009 02:30:03 +0000

The process behind this blog has always aimed to be one big post a week that framed a particular aspect of my research, followed by a series of smaller supporting or conflicting posts throughout the week. These smaller posts intending to encourage contribution and consensus by the end of the week and are intended to focus on real world or anecdotal application of that week’s research question. Thus far I’ve shared thoughts and observations from my research into Intrinsically Motivating Design and supported Skill Acquisition in the design of products and services. I’ve also volunteered some of the thinking from my experiences in designing for public engagement.

Ever been left frustrated by a system, product or service that didn't work the way you wanted it to? Photo from: Maryam Kh

This week I’m going to try and do it in more of an active problem solving sort of way, responding to the design brief of designing for democratic regime change. In other words, as a designer of systems, products and services what can I contribute from my research to enable and empower individuals striving to undermine an autocratic regime. Contentious – yes. Interesting – yes. Educational – yes.

Hopefully, if I do a good enough job, this will be a nice theoretical study into motivational design and to positively influencing human behaviour. Indeed, this exercise might provide an insight into understanding contrary behaviour, which is to say systems, products and services that aren’t designed to motivate or empower their users or might be actively implemented to demotivate and dis-empower them. My hope is that this exercise will provide a valuable and unique insight into better designing dynamic systems and services to better support the intentions and will of the majority of it’s users. I hope you will see this as something worth contributing to or at least broadcasting further afield, it is certainly not intended to be prescriptive and as far as it is published here is purely a theoretical discussion, although clearly influenced by powerful recent world events.

The video that inspired this post. What motivates the behaviour that lead to this incident and what can we as designers do to prevent its reoccurance?

Is Design a Skilled or Procedural Process? Or Both?

Fjbisset — Thu, 18 Jun 2009 10:49:11 +0000

Following on from recent posts on the nature of design thinking I want to clarify two things. I am not opposed to design thinking or even thinking about design as this blog demonstrates! Simply, my thoughts as expressed here were that if you want people to better understand design thinking, just get on with it an involve them in it or at the very least provide them with a concrete example rather than an abstract diagram of the process you are trying to sell them. This could perhaps be considered a Constructivist viewpoint as opposed to a Cognitivist world view.

Scenario modelling can also be considered a constructivist tool. As a designer you probably use scenario modelling to predict, impose or evaluate user behaviour by ‘constructing’ that world in some manner. This might be virtually or in the form of organised user testing and evaluation. Do you use scenario modelling to anticipate or communicate your own role within the design process?

Rules by Wm Yas on Flickr

The second issue I want to explore and it relates to this earlier post as well. Is the question of whether design is a skill or rule based process?

Systems and therefore ‘systems theory’ in it’s purest form requires human operators whether designer or user to follow a defined path or at least operate within a set of constraints. I interpret the ‘design thinking’ as practiced and encouraged by IDEO, with their method cards etc. as ‘rule based’ at least in the deductive phase (understanding the context) of the design process.

Do you follow a rule based or heuristic approach as part of your efforts to understand or predict the environment and users you are designing for? Does it work?

Other designers of course may rely simply on their own subjective or ‘skill based’ judgements about the environment or context as opposed to following a rule or heuristic approach to design. This is perhaps symptomatic of the ‘ego-design’ process that Molenbrook refers to here, in describing the differing approaches many designers have to ergonomics data.

Most importantly, which of these ways of conceptualising the design process are easier to engage clients, users and yourselves as designers with?

The Logic of Design Thinking

Fjbisset — Sun, 14 Jun 2009 10:22:47 +0000

In an attempt to better disentangle the continued discussion on the role of systems thinking or ‘logical processing’ in ‘design thinking’, as continued here and here yesterday. I’ve had a crack at boiling it down to basic principles – in true systems fashion!

Phrased in Aristotelian terms ‘design thinking’ or more generally any problem solving exercise, consists of three cyclical phases. Depending on the view to which you subscribe, these three phases are not mutually exclusive, but the overall process could be initiated by beginning with any one of the following processes:

Abductive Phase – Idea - The guess or hypothesis, that intuitive or highly creative leap, the game changing, out of the box idea. A highly skilled and intuitive phase of the design process. The quality of this phase is often assessed depending on the quality of it’s rhetoric or presentation (the design pitch). Highly context specific in the sense that you will need to have a good understanding of the context in question in order to make such an intuitive jump.

Deductive Phase – Development – The logical scientific part of the process where it is ascertained whether this creative leap is in fact valid or appropriate. This is the bit where you have to convince the engineers and money men. My feeling is that it is this context independent phase of the design process that is the area where systems thinking may be most valuable.

Inductive Phase - Testing – Another context dependent phase where ultimately the ideas and that processes that you have used to realise it are tested and evaluated. This could either be formal user testing or this could occur informally whilst the product is in the market place.

As it stands above it is probably more akin to a traditional ‘ego-design’ process, whereby the designer thinks that the strength of his idea alone is enough to justify the end result. As I perceive it, many more recent service and human-centred design processes and arguably the ‘design thinking’ approach as practiced by IDEO themselves might run as follows:

Deductive Phase (Rule Based) (Context Sensitive) - Understanding the context and user requirements, what familar ‘rules’ (or methods) are applicable in this domain?
Inductive Phase (Knowledge Based) (Context Independent) – Prototyping and testing of chosen ‘rules’ to assess validity to identified problem as well as other engineering and financial constraints.
Abductive Phase (Skill Based) (Context Sensitive) – Leading to final design proposal or creative leap (with associated user involvement, empowerment and motivation).

Thus it is clear to from this definition how ‘systems thinking’ or Jaimes Nel’s ‘black box’ i.e. the deductive, rule-based phase of the deisgn process can help deduce appropriate design ideas and solutions to design problems – arguably the true value of ‘design thinking’.

My own feeling from this definition however, is that it is purely the deductive phase of ‘design thinking’ to which any form of systems thinking or conceptualisation should be directed. Attempting to apply it to the other context and skill based parts of the process would as Collopy warns undermine the essence of ‘design thinking’.
