Requirements Repository

• Automatic versioning of requirements deliverables– Access to past versions

• Baselining– Control which versions of deliverables go with which– Facilitates traceability

• Communication– All versions are accessible by all stakeholders

• Generate documents from the repository– As and when needed

Baseline

“A set of specifications….that has been formally reviewed and agreed on, which thereafter serves as the basis for further development, and can only be changed through change control procedures.”

Change Control

The purpose of change control is to ensure that

we build exactly the right product

Once Upon a Time…

A software application was delivered on time, within budget, and met scope and quality objectives.

The business domain was complicated; requirements kept changing and the users kept changing their minds

It was staffed by ordinary people: analysts, designers, developers, …Even the subject matter experts were ordinary.

The team was distributed in 5 cities in 3 countries across 12 time zones and they spoke at least 3 different languages

Instead of “documents”, they relied on a requirements repository.

Best Practices• Manage requirements deliverables, not

requirements documents– A document is just a snapshot

• A milestone

• Each requirements deliverable has its own life cycle– Use a repository tool

• Versioning, managing baselines, team communication

• Change control begins with the first baseline– Rigorously enforced

• To ensure that we build exactly the right product
