Development methodologies

Collecting terms software engineers use everyday, but often with different meanings.

Agile, scrum, extreme programming

Agile is an iterative way of managing projects based on a set of principles.

Iteration is the repetition of a process in order to generate a sequence of outcomes. Each repetition of the process is a single iteration, and the outcome of each iteration is then the starting point of the next iteration. - Wikipedia

We can repeat the same process in every iteration:

• define tasks
• estimate
• identify goal
• execute
• release
• review

Or alternate between different processes:

• exploring and refining requirements
• extending and reducing complexity
• prototyping and validating
• implementing and testing

Agile is a set of principles, scrum is a framework.

What are these principles? - See Agile manifesto

What is this framework about?

• defines 3 roles: PO, SM, developer (note that the architect is not one)
• organises iterations

Scrum criticism: very well defined (opposing the principle of interactions over tools)

Extreme programming is another framework?

take best practices to an extreme level.

Theme, epic, story, task

We organise work items into groups and hierarchies. But what is the baseline in this structure?

User story

• written in simple language, from the perspective of the end user
• focuses on the end goal, team details requirements later
• written by product owner, later discussed by the team on planning

Epic

• TODO: what is an epic?

Milestone?

Boards

We can use boards to visualize work and limit items. The end goal is to see who works on what.

Kanban

• tickets
• columns
• limits

Scrum

• track iteration
