I gave this talk at the IA Summit in New Orleans on March 25, 2012. Here's the talk description: It’s part of our job to talk to people to figure out complex situations. To build things people love, we have to understand not only users, but also the wider context we’re working in: people, systems, structures, business models, and more. The need to think the user experience through on several channels challenges us to envision a system that is cohesive and delivers delightful experiences. Business analysis, computer science and psychology offer different frameworks and tools to help to make sense of a messy situation, to articulate and visualize the problem. In this talk, I will present a selection of techniques that are relevant to UX, such as Soft Systems Methodology or the Business Model Canvas. You will walk away with: - Knowledge about systems thinking theory - An understanding of how systems thinking methods can be used as part of a UX process, incl. tools and techniques

- 36. The intuitive mind is a sacred gift and the rational mind is a faithful servant. We have created a society that honors the servant and has forgotten the gift. We will not solve the problems of the world from the same level of thinking we were at when we created them. More than anything else, this new century demands new thinking: We must change our materially based analyses of the world around us to include broader, more multidimensional perspectives. ~Albert Einstein #IAS12 - @johannakoll

- examples: eg hard system = thermostat, motherboard. soft system = game of poker, soccer game, meeting, healthcare.
- Worldview is a concept for empathyConsider:- roles that people adopt in the situation (which may be formally recognised or quite informal); the norms which govern people’s behaviour; and the values they espouse.- political aspects of the situation, in other words recognition of the different interests that are represented and how these different interests are accommodated.
- BM channels = connections
- walk through from customers perspective, and other perspectivesWorldview, interconnections, dependenciesZoom out and consider the wider contextWhat processes are necessary to deliver value to customers?Models are dynamic, not static
- 2 types of flows. First one is material and stock flows. Stocks change over time through the actions of flow. Stocks act as buffers or delays, and help a system to stay in balance.You can also apply this to people. Shows limits to growth if your resources aren’t endless. Key is to understand and monitor system behaviour over time. Do not focus on only individual events.The second type are information flows. While it’s hard to changephysical structure, materials, resources, changing how information isdistributed and presented in a system can have major impact. "Information holds systems together and plays a great role in determining how they operate. Most of what goes wrong in systems goes wrong because of biased, late, or missing information." (Meadows)Adding or restoring information can be a powerful intervention, usually much easier and cheaper than rebuilding physical infrastructure.
- Reinforcing feedback loopsA positive feedback loop is self-reinforcing. The more it works, the more it gains power to work some more.Positive feedback loops drive growth, explosion, erosion, and collapse in systems. A system with an unchecked positive loop ultimately will destroy itself. Usually negative feedback loop kicks in, eg epidemic runs out of infectable people—or people take increasingly strong steps to avoid being infected.Reducing the gain around a positive loop—slowing the growth—is usually a more powerful leverage point in systems than strengthening negative loops, and much preferable to letting the positive loop run.(...) control must involve slowing down the positive feedbacks.Balancing feedback loop A negative feedback loop needs a goal and a response mechanism. Self-correct the system, often inactive = emergency mechanisms. Seem costly as inactive, removing them has little impact in the short-term, neglect the long-term impact.Here are some other examples of strengthening negative feedback controls to improve a system's self-correcting abilities: preventive medicine, exercise, and good nutrition to bolster the body's ability to fight disease, pollution taxes.The information delivered by a feedback loop - even nonphysical feedback - can only affect future behaviour; it can't deliver a signal fast enough to correct behaviour that drove the current feedback. There will always be delays in responding.The loop that dominates the system will determine the behaviour.Consider the driving factors, how they might behave, and what drives them.! Dynamic systems studies are not designed to predict what will happen, but to explore what would happen if... --> system dynamics models explore possible futures and ask 'what if' questions.
- Focus on trends over time rather than single events. Learn if the system is approaching a goal or limit.Inventory = stock (could also be information)
- What came before?What might happen next?
- Talking to people, empathy, intuitionhumanise the data – tell a storyInformation flows enable other things in the system to happenConsider the feedback loopsObserve customer behavior over timeUse qualitative findings and your gut
