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.
