Software release

Finally we approach the release state for the software, after all of the hard work the team did we deserve to release quality product. Since we are using the staged delivering approach we need to make sure that every stage of the project is in a releasable state, this is a hard work for the programmers, since much of the work must be making the project in to a useful release state the main activity relies on polishing the code and eliminating most of the bugs.

“We avoid releasing a software product in this state”. – Project team developer maybe.

When to release

The answer must teeter on the line between releasing poor quality software early and releasing high quality software late. Severe methods can help you base the answers to this questions on a firmer footing than the instinctive guesses.

Defect counts.

By comparing the number of defect code this week with the past week you can know how close is the project to completion. If the number of defects this week exceeds the number of defects resolved this week then the software still has miles to go.

Statistics on effort per defect.

The data on time required to fix defects categorized by type of defect will provide a basis for estimating remaining defect correction work for this and future projects.

Defect density prediction.

One of the easiest to judge whether a program is ready to release is to measure its defect density. The number of defects per line of code. The more historical project data you have the more confidence you can be in the prerelease defect density targets.
