Change is inevitable

• All Projects are subject to change… a high risk challenge

– Increasing number of contributors & stakeholders

– Agility needs reactivity

– Usability is key

• Change may impact the agreed baseline of Requirements

– Need a formal organization-tuned process,

– Assess, decide, communicate

• Change traceability

– Relate project Development activities to Requirements and Change Management decisions

– Establish a full audit trail

– Need to record and manage change impacting all project artifacts

DOORS/Change empowers your Requirements Change Request Process

• Predefined, customizable Lifecycles, allowing assignment, multiple reviewers, electronic signatures

– Web-based submission, transitions, analysis history, reporting

– Work on the Requirements is carried out inside DOORS

Changes are proposed against

requirements

Proposed Changes

are assessed and approved

Proposed Changes

are applied

Working against a Requirement Change Request

• Setting the default RCR indicates that all changes are to be tracked against this context

– DOORS/Change builds the traceability report automatically

– Enforced process control can be activated

Unrivalled usability

• DOORS/Change brings critical enterprise functionality with no additional learning curve

• Users work as they normally would in DOORS

– Changes are automatically tracked

• Effortless, intuitive change control of:
