Assigning Responsibilities to Individuals
Assigning Responsibilities to Individuals

As project manager, your role in staff acquisition and assignment is to determine the specific time, cost, and resource commitments required to complete the project. This must be done for every activity. Some of these cannot be completed until after more planning has occurred,

Identifying and Documenting the Project Roles and Skills Needed
Identifying and Documenting the Project Roles and Skills Needed

The project manager has to make a decision who does what and who decides what on the project. Deciding who does what is an exercise in career planning, balancing learning opportunities against accomplishing work on time and managing egos. The particular skills required for

Assigning Resources
Assigning Resources

When you have a WBS list of modified activities that match the life cycle you have selected for a project, you are ready to allocate resources to them. This should be easy, right? The database people get the database assignments, and the testers get the testing assignments. Not so

Estimating Duration and Cost - Summary
Estimating Duration and Cost - Summary

Estimating product size, staff effort, project schedule, and cost are inextricably entwined during the project planning process, which takes place for the first time near the beginning of the project life cycle and many times thereafter, generally at the end of each major phase.

SLIM - A Mathematical Model
SLIM - A Mathematical Model

With regression modeling, the stress is on constructing a formula that best represents scattered data points. In mathematical modeling, the stress is on matching the data to the form of an existing mathematical function. In the early 1960s, Peter V. Norden of IBM concluded that

COCOMO II
COCOMO II

COCOMO II is a revised and extended version of the model, built upon the original COCOMO. It more easily allows the estimation of object-oriented software, software created via spiral or evolutionary models, and applications developed from commercial-off-the-shelf software. It

Detailed COCOMO
Detailed COCOMO

This is the most complicated version of the COCOMO model. It involves the following further steps: The program is decomposed into particular products and components of products. Boehm calls this the three-level product hierarchy: system, subsystem, and module. The top level, the system level, is used to apply major overall project relations such as nominal effort and

Basic COCOMO Phase Distribution of Effort and Schedule
Basic COCOMO Phase Distribution of Effort and Schedule

As well as estimating development effort and schedule, it is often necessary to estimate how the effort is distributed among the primary life cycle activities. COCOMO takes a pretty simplistic view of the life cycle phases, considering only plans and requirements, product design,

COCOMO : A Regression Model
COCOMO : A Regression Model

The COnstructive COst MOdel (COCOMO) is perhaps the most extensively used estimating technique. It is a regression-based model developed by Dr. Barry W. Boehm when he was at TRW in the early 1970s. He began by analyzing 63 software projects of various types. The
