COCOMO II Model The post-architecture model is the most detailed of the COCOMO II models. The estimate produced at the post-architecture level are based on the basic formula PM=AxSize^BxM used in the early design estimates, where PM stands estimate effort in terms of person month, M stands multiplier, Size indicates system size in terms of KDSI (thousands of source line instructions), A and B are the constant factors. The attributes that are used to adjust the initial estimates and create multiplier M in the post-architecture model are called cost drivers. In this question, we would like to see how cost drivers influence the effort estimate. Given a project, a value for the exponent B of 1.17 has been estimated. System size is 128KDSI. A (a constant factor) has been estimated as 2.5. Here, we assume that reliability, complexity, memory constraint, tool use and schedule are the key cost drivers in the project. All of the other cost drivers have nominal value of 1. The detail multiplier of each cost driver is listed in the following table. Cost Drivers | Estimate Reliability | Very High, multiplier = 1.39 Complexity | Very High, multiplier = 1.3 Memory constraint | High, multiplier = 1.21 Tool use | Low, multiplier = 1.12 Schedule | Accelerated, multiplier = 1.29 Questions: 1. Calculate initial COCOMO estimate without cost drivers. 2. Calculate adjusted COCOMO estimate with consideration of the cost drivers.
