  • Design as the Serendipity of Location

    Design as the Serendipity of Location

    I can’t help but reflect on the similarities between research methods, processes and outcomes, and design methods, processes and outcomes. I read an article which argued that there were two types of people: people with tidy offices and people with untidy offices. Tidy-office people are organized and so can find anything they need. These are the people who work top-down, creating an outline then writing or designing according to that scheme. Untidy-office people are disorganized, spend a great deal of time searching for things, but also tend 1 to be more creative because they are inspired by things which they bump into, while looking for other things. These people work bottom-up, assembling elements into a coherent whole. The article argued that there are cognitive rewards in both styles of working, that lead people to subconsciously adopt one or the other style consistently.

    I was reflecting on this as I try to make sense of the piles of material that I have assembled for the book. I am definitely an untidy-office type and I wonder if this has something to do with introvert/extrovert personalities? [My project management students and I just explored an online Myers-Briggs personality test; as expected, I was an INTP type.] Perhaps introverts just prefer a “life of the mind,” where we can construct inductive models of the real world?2

    My semi-organized and shifting piles of research data, models and representations, interim findings, academic articles, and books provide a three-dimensional, systemic representation of design processes that can be reorganized as I comprehend different patterns. Of course, they are both preceded and supplemented by painstaking (and frequently revisited) processes of categorization, synthesis, and validation. But the kaleidoscope of patterns that they reflect is invaluable in suggesting different views of my findings. The same is true for design – we create the patterns that we perceive as relevant in the problem situation. As our perceptions shift, so do the design patterns that we follow.

    I would argue that innovative design is neither deductive or inductive, but consists of cycles of induction and deduction. It follows a hermeneutic circle of sensemaking, as designers attempt to work from an abstract problem to concrete fragments of a solution that solve those sub-components of the problem that they understand, then relate these back to a meaningful, integrated problem definition. This combination of deductive and inductive thinking has been described as abductive reasoning, but reasoning about design is more disciplined and rigorous than most descriptions of abduction [a hunch] would indicate. I prefer Thagard and Shelley’s (1997) argument that hypotheses about reality are layered, incomplete, and too complex to be comprehended easily3. Often, the only way to comprehend complex, interrelated elements of behavior and context is to use a visual, systemic representation and an iterative process of decomposition into parts of the solution that you understand, integration back to a coherent problem-definition, then back to decomposition until the design as a whole makes some sense.

    As someone who has spent a good portion of their career as a systems designer, I have never considered design creative. Design is more about synthesizing from preconceived elements than creating from scratch4. We need to be sensitized to contextually-relevant components of a solution in order to synthesize a design.

    So I wonder if – just as in research – the greatest inspiration in design derives from the serendipity of location? Being in the right place, at the right time, to see elements that can be reused in designing a specific solution to a complex and ill-understood problem.

  • Design as a trajectory of goal-definitions

    Design as a trajectory of goal-definitions

    The focus of IS design has moved “upstream” of the waterfall model, from technical design to the co-design of business-processes and IT systems.  This focus requires an improvisational design approach.  IT-related organizational innovation deals with wicked problems. 

    Wicked problems tend to span functional and organizational boundaries as business process and information management problems are intertwined.  There are clusters of interrelated problems:  these cannot be defined objectively because the problem is defined differently, depending on who you ask.  IS designers cannot analyze this type of problem in isolation – we need to involve diverse groups of stakeholders in negotiating suitable problem definitions and boundaries for change.  But wicked problems also involve distributed knowledge, where understanding of the problems is stretched across (rather than shared between) stakeholders. 

    So design goals evolve, as designers and stakeholders learn more about the context and the problems facing the organization by engaging in incremental change.   This is often approached by means of agile design methods. But our lack of understanding about how to establish a “common language” for this type of design means that information system innovation tends to be pretty hit-and-miss. Most design initiatives spend more time arguing about process definitions than achieving change. We need a new approach that focuses on the co-design of business (process) and IT systems: a collaborative process that involves problem stakeholders as collaborators in analyzing change. This is the basis of improvisational design.

    Goal Emergence in Design

    The collaborative design of system solutions for wicked problems seems to follow a trajectory of goals, as the group’s understanding of the design progresses. The key to making (and evaluating) progress is understanding what triggers the changes in goal-direction.

    From my research studies, it seems that goal changes are triggered by breakdowns in individual buy-in to the group’s consensus definition of the design vision. Both the breakdowns and the most important parts of the vision are concerned with how the design problem is structured and defined — not (as we usually assume) how the designed system will work. Of course, the solution is important: individual group members constantly test their understanding of the problem against the emerging solution, then realize that the design goals need to change. But it is the consensus problem-vision that drives design goals.

    An important implication of this design model is how to manage design effectively. We need to keep influential decision-makers in the loop, when design goals are redefined, or they just see the start and end points. The natural response is “what took you so long?”. Managing external expectations is key to design success.
