CS605 Solved Assignment No. 2

Due Date: 29/5/2014 

Q.1

 An automobile company wants to develop an Inventory Control System for its business. The project manager has been asked to develop an Inventory Control System on urgent basis. AS an I.T. consultant what you will decide whether to build software will be more cost effective or there are other options to be adopted to get software on urgent basis.

Solution:

AS an I.T. consultant we will get software on urgent basis. we know the time is short so 1st thing developing software and in this scenario testing is also a time consuming process. It needs lots of development after implementation also on the other hand if we chose stable software which is already tested will be best option.

Question No. 2

From the following graph (for a certain component), compute and determine that either we should build or buy it.      

                                                                                                                    

Solution:

expected cost: = å (Path probability)₁ x (estimated path cost)

Using above mentioned formula:

Expected Cost _build  = (0.3x 119 + 0.7x 118) =  118.3

Expected Cost _buy  = (0.3x 111 + 0.7x 114) = 113.1

so proved buy is better than build. 

Q.3

For software project estimation, a project manager can use historic data about its organization previous projects. Suggest some statistical technique / model for project estimation.                        

Some techniques  used in Software Engineering are as under: 

• Stable Activities 
• Analogous Estimating 
• Parametric Model Estimating 
• 3 Point Estimating 
• Dependent Activities 
• Uncertain Activities
