Estimation Techniques(Cocomo-2)

Q1: With object points to estimate effort for an airline sales system that is to build. This is a new project, and the back-end database server has been built, requires 40% as a new

component. At the early stage, we need: 5 booking screens with 3 clients, 3 servers to record a new advertising sale booking. 9 pricing screens with 4 servers, 7 clients showing

the advertising rate for each day and each flight contains average 2 availability screen showing which flights are available. 5 level sales report with 1 server, 2 clients showing total sales for the month and year, and 1 3GL component. Consider developer experience and maturity level as nominal.Perform step wise calculation along with formulas. Use The Cost Driver Table Below

STEPS OF APPLICATION COMPOSITION MODEL - Step-2: Classify complexity levels of each object STEPS OF APPLICATION COMPOSITION MODEL - Step-3.Assign complexity weights to each object - The weights are ined for three object types ie. streens, report and 3GL component. Complesity weight are assigned according to objectr complexity level using following table STEPS OF APPLICATION COMPOSITION MODEL - Step-6: Calculate Productivity nate (PROD) - Productivity rate is calculated on the bassis of information ziven abost developer's experience and capabiliy for calculating it, wo une followeng able STEPS OF APPLICATION COMPOSITION MODEL - Step-2: Classify complexity levels of each object Fer Screens Fer Reports STEPS OF APPLICATION COMPOSITION MODEL - Step-3:Assign complexity weights to each object - The weights are used for three object types i.e, screens, reports and 3GL components. Complexity weight are assigned according to object's complexity level using following table Complexity Weight STEPS OF APPLICATION COMPOSITION MODEL - Step-6: Calculate Productivity rate (PROD) - Productivity rate is calculated on the basis of information given about developer's experience and capability. For calculating it, we use following table
