Implementation Reuse

Definition

Implementation reuse is the implementation task during which existing data, hardware, and software components are reused during development.

Objectives

The typical objectives of implementation reuse are to:

• Maximize quality.
• Minimize development (and maintenance) costs.
• Minimize development schedule.
• Minimize development risk.

Preconditions

Implementation reuse can typically begin when the following preconditions hold:

• The relevant requirements are specified.
• The relevant architecture has been documented.
• Appropriate reusable components exist.

Completion Criteria

Implementation reuse is typically complete when the following postconditions hold:

• TBD

Steps

Implementation reuse typically involves the following teams performing the following steps:

• TBD

Techniques

Design reuse can typically be performed using the following techniques:

• TBD

Work Products

Implementation reuse typically results in the production of the following work products:

• Data components.
• Hardware components.
• Software components.

Guidelines

• It is typically better to reuse components than to develop them.
