Win-Win Spiral Model



 1.    The WIN-WIN model also suggests proper communication with customer. In reality customer and developers undergo through the process of negotiation. Successful negotiation occurs when both the sides win. This is called win-win result.
2.    Customer’s win means - Obtaining the system that satisfies most of the needs.
3.    Developer’s win means - Getting the work done with realistic and achievable budgets and deadlines.
4.    In WIN-WN spiral model negotiation activities are carried out at the beginning of each pass of the spiral.
5.    Various activities that can be carried out in WIN-WIN spiral model are
a.     Identification of ‘stakeholders’
b.    Determination of ‘stakeholders’ wins condition
c.     Negotiations of stakeholders striving for win condition. With the concerned software project team reconcile for win-win result. Then determine next level objectives, constraints and alternatives.
d.    Analyze and resolve the risks.
e.     Define next level of product and process.
f.      Validate process and product definitions.
g.    Take a review of product and give necessary comments on it.
6.    There are three anchor points that can be defined in WIN-WIN spiral model
a.     LCO – That means Life Cycle Objective. It defines the objectives for major software engineering activities.
b.    LCA – That means Life Cycle Architecture. It defines the software architectures that can be produced with all the objectives are set.
c.     IOC – That means Initial Operational Capability. It represents software with all the desired initial operational capabilities.
