Intro

coding is not as hard as collaborating

Listen to your customer

First create a project mission based on business goals..

Test Driven Development

impractical

most of the cost in software comes from feedback delay

1. All tests run and pass 2. Remove duplication 3. Remove opacity 4. Remove complexity

THE CODE IS TERRIBLE!! WE NEED ONE SPRINT TO REFACTOR

There is no refactoring without tests There is no testing without refactoring

refactoring === design

Focus on Quality over Schedule

But what causes poor Outer Quality?

Lack of automated acceptance tests Lack of customer involvement Team not focused on Project Mission Lack of Inner Quality

How do you ensure Outer Quality?

Example workshops Automate acceptance tests Have a sprint vision statement Sign off during Sprint

How do you ensure Inner Quality?

2 developers sharing a screen working on the same task

What is Pair Programming about?

Jon Jagger's Principles of Improvement

Pair programming is about improving faster

Strengthening the case for pair programming

Should pairs be kept together?

Code Katas

Description:

Explore efficiency versus effectiveness in software development through this conference talk from PHP UK Conference 2013. Delve into the benefits of "impractical" practices like Test-Driven Development (TDD) and pair programming. Learn how to focus on quality over schedule, ensure both inner and outer quality in projects, and understand the principles of improvement in coding practices. Discover techniques for creating effective project missions, automating acceptance tests, and involving customers in the development process. Gain insights on refactoring, code katas, and the importance of collaborative coding. Challenge traditional notions of efficiency and learn how seemingly impractical methods can lead to more effective software development outcomes.
