Write short note on the various estimation techniques.
Algorithmic cost modelling - the cost estimation is depend on the size of the software. Expert judgement - The experts from software development and the application domain apply their experience to estimate software costs.
Estimation by analogy - The price of a project is computed by comparing the project to a like project in the same application domain and then cost can be computed. Parkinson's law - The cost is determined by available resources rather than by objective assessment. Pricing to win - The project costs whatever the customer ready to pay out it.
