The Wall of Confusion

Impact of a poor DevEx Cochran, T. (2021)

What is DevEx? Developer Experience is about creating an environment in which a developer can do their best work.

How do developers feel about the processes, systems and services they use?

Why is DevEx important? Developer productivity underpins the success of your organisation.

Srivasta, S. et al. (2020)

Hire expensive developers and make it hard to do their jobs . . Profit?

DevEx is contextual Developers exist in an environment that is unique to your organisation and environment ?

A good developer experience is emergent

Good fences make good neighbours

How do we measure DevEx?

The SPACE Framework S - Satisfaction and Well-being P - Performance A - Activity C - Communication and Collaboration E - Efficiency and flow Yu, A. (2021)

Key findings Finding flow is key, and interruptions are a drag. Minimal or no interruptions give developers an 82% chance of having a good day, but interruptions throughout the day decrease the chance of a good day to just 7%. Meetings are both awesome and terrible. Collaboration improves our work, but too many meetings can be a blocker; going from two to three meetings per day lowered the chances of developers making progress toward their goals by 60%. A two minute daily reflection can help developers improve their days

Why?

A good Developer Experience helps devs find flow and reduces interruptions

A good Developer Experience reduces the cognitive load for a developer

A good Developer Experience creates an environment of psychological safety
