Role: Implementer
This role develops software components and performs developer testing for integration into larger subsystems, in accordance with the project's adopted standards.
Main Description

The implementer role is responsible for developing and testing components, in accordance with the project's adopted standards, for integration into larger subsystems. When test components, such as drivers or stubs, must be created to support testing, the implementer is also responsible for developing and testing the test components and corresponding subsystems.

Multiple Occurrences

The appropriate skills and knowledge for the implementer include:

  • knowledge of the system or application under test
  • familiarity with testing and test automation tools
  • programming skills
Assignment Approaches

An implementer may be assigned responsibility for implementing a structural part of the system (such as a class or implementation subsystem), or a functional part of the system, such as a use-case realization or feature.

It is common for a person to act as both implementer and designer, taking on the responsibilities of both roles.

It is possible for two persons to act as the implementer for a single part of the system, either by dividing responsibilities between themselves or by performing tasks together, as in a pair-programming approach.
