The success or failure of a new system
rests squarely on the always shifting, sometimes frustrating art of requirements
definition. There is no complete set of requirements out there just
waiting to be discovered. Requirements must be negotiated among the
success-critical stakeholders who are unsure of their own needs, much less
the needs of others. EasyWinWin is both a collaborative platform
and a step-by-step methodology for bringing key stakeholders together to
hammer out a set of requirements with which they can all live. Using
EasyWinWin, teams produce requirements in far more detail with less pain
and in less time than was ever previously possible. Because
issues surface far earlier in the project, expenses and delays associated
with rework drop substantially.
The win-win requirements negotiation approach is
based on the principle that making winners of the key stakeholders is a
prerequisite for the success of any project. EasyWinWin is an innovative,
new implementation of the WinWin approach that aims at enhancing the directness,
extent, and frequency of stakeholder interaction in requirements engineering.
EasyWinWin is based on the groupware product GroupSystems and uses group
productivity tools (electronic brainstorming, categorizing, voting, etc.)
to improve the involvement of stakeholders and facilitate stakeholder interaction
in the Requirements Engineering process.
Different stakeholders – users, customers, managers,
domain experts, and developers – come to the project with different expectations
and interests. EasyWinWin moves these stakeholders through a learning
process: Developers learn more about the customer’s and user’s world, while
customers and users learn more about what is technically feasible. Requirements
are negotiated to achieve mutually satisfactory agreements. Requirements
negotiation is based on stakeholder co-operation and active involvement
We will introduce the WinWin negotiation model, and
present the EasyWinWin approach. We will give a live demonstration
the collaborative tools and the methodology in action. We will present
the highlights from several case studies in which we used the approach.
