A good user experience depends on …

November 26, 2017

A good user experience depends on:

  • Clear structure and navigation flows;
  • Compelling and clear visual design;
  • Great copy and tone of voice;
  • Thoughtful transitions and animations;
  • The app’s performance and speed;
  • The user’s mobile phone performance and speed;
  • The user’s internet connection;
  • The product making sense to that user;
  • The product adding value to what that user needs;
  • A clear understanding by the user of what the product does;
  • How accessible the product is;
  • The user’s social, cultural and demographic context;
  • Where the user is at the time they engage with the app;
  • Everything the user has seen in their entire life;
  • How the user is feeling that particular day they use the product;
  • Etc, etc, etc.

Focus state

November 13, 2017

I always recommend that if content changes on mouse hover, the same should occur on keyboard focus. In almost all cases you need to add “a:focus” wherever you have “a:hover” to achieve this.

Behavioral insights

November 3, 2017

EAST framework

  • E-asy
    • Harness the power of defaults. – We have a strong tendency to go with the
      default or pre-set option, since it is easy to do so. Making an option the
      default makes it more likely to be adopted.
    • Reduce the ‘hassle factor’ of taking up a service.- The effort required to
      perform an action often puts people off. Reducing the effort required can
      increase uptake or response rates.
    • Simplify messages – Making the message clear often results in a significant

      increase in response rates to communications. In particular, it’s useful to
      identify how a complex goal can be broken down into simpler, easier actions.
  • A-ttractive
    • Attract attention. – We are more likely to do something that our attention
      is drawn towards. Ways of doing this include the use of images, colour or
      personalisation.
    • Design rewards and sanctions for maximum effect. – Financial incentives are
      often highly effective, but alternative incentive designs — such as lotteries —
      also work well and often cost less
  • S-ocial
    • Show that most people perform the desired behaviour. – Describing what most people do in a particular situation encourages others to do the
      same. Similarly, policy makers should be wary of inadvertently reinforcing
      a problematic behaviour by emphasising its high prevalence.
    • Use the power of networks. – We are embedded in a network of social
      relationships, and those we come into contact with shape our actions.
      Governments can foster networks to enable collective action, provide
      mutual support, and encourage behaviours to spread peer-to-peer.
    • Encourage people to make a commitment to others. – We often use
      commitment devices to voluntarily ‘lock ourselves’ into doing something
      in advance. The social nature of these commitments is often crucial.
  • T-imely
    • Prompt people when they are likely to be most receptive. – The same offer made at different times can have drastically different levels of success.
      Behaviour is generally easier to change when habits are already disrupted,
      such as around major life events.
    • Consider the immediate costs and benefits. – We are more influenced by costs
      and benefits that take effect immediately than those delivered later. Policy
      makers should consider whether the immediate costs or benefits can be
      adjusted (even slightly), given that they are so influential.
    • Help people plan their response to events. – There is a substantial gap between intentions and actual behaviour. A proven solution is to prompt people to identify the barriers to action, and develop a specific plan to address them.
The EAST framework is at the heart of this methodology, but it cannot be applied in isolation from a good understanding of the nature and context of the problem. Therefore, we have developed a fuller method for developing projects, which has four main stages:
  1. Define the outcome – Identify exactly what behaviour is to be influenced. Consider how this can be measured reliably and efficiently. Establish how large a change would make the project worthwhile, and over what time period.
  2. Understand the context – Visit the situations and people involved in the behaviour, and understand the context from their perspective. Use this opportunity to develop new insights and design a sensitive and feasible intervention.
  3. Build your intervention – Use the EAST framework to generate your behavioural insights. This is likely to be an iterative process that returns to the two steps above.
  4. Test, learn, adapt – Put your intervention into practice so its effects can be reliably measured. Wherever possible, BIT attempts to use randomised controlled trials to evaluate its interventions. These introduce a control group so you can understand what would have happened if you had done nothing.

Nonlinear human behaviour
