Managing RequirementsUnderstanding and using requirements

Requirements are located in many documents, charts and modelsRequirements lack contextRequirements are not used by designers, developers and testers

Organizing and reporting on requirementsRequirements are not assigned priority, risk and level of effortRequirements do not have any definition or type

Managing changes to requirementsNo record of relationships or originChanges are not communicated in a timely mannerImpact of change is not assessed or underestimated

Unsolved RM Challenges Software Rework Cost, Delays, Quality Issues

RequisiteProRequirement Management with easeCommunicating Changes and Their Impact

“It’s very easy to skip over requirements or make assumptions.

Rational RequisitePro drives us to make sure we've covered everything.”

Linda Horne, Cygent

“With Rational RequisitePro's suspect links, my team

members and I can immediately see changes that are made…”

Geographic distribution of business – the new norm

Work realignment based on:Customer locationIncreased global reachDomestic market needs

Right-sourcing based on:Management, support and enhancement on non-critical IT (Outsourcing)Mobile workforceLower cost to execute integral business processes like help desk, call centers, and hostingAvailability of talent (Off-shoring)

Distributed Development based on:Core application developmentIndividual ComponentsMoving toward Application Modernization, Code Factories, Industry specific development and Architecture planning

Distributed Development - Common Pitfalls

Multiple Development Sites generate confusion:

Conflicting Processes

Varying Project requirements

Change Management and Version Control

Measuring project progress & quality

Overall Project control

IBM Software Group

25

Poor Distributed Development – Root Causes Communications issues – time lag, cultural, political, project visibility, work transfer mistakes, security, and ownership

Requirements not well defined up front

Requirements management process does not provide feedback loop, or method for communicating changing / evolving requirements

Requirements well defined, but not well communicated

Organizational issues – lack of team motivation

Process (handoff, delivery, change management) not well understood –time spent trying to figure out who does what

Additional project management overhead

Mismatched and unsynchronized configuration management processesand systems – resulting in classic configuration management problems –work to know what files to work on, what is the latest build, why did the build break, etc.

Process: A “Must-have”In Distributed Development

Identifies resources requirements

Defines team responsibilities and their relationship with other team members

Reduces risk

Assists project planningand cost estimation
