![]() Staffing Level Estimation: Putnam's Work Putnam analyzed that characteristic of software development and staffing has some characteristics of R and D projects studied by Norden and Rayleigh Norden Curve can be used to Relate the Number of delivered lines of code to the effort and the time required to develop the project. Td= time at with the curve attains its maximum values. He represented the Rayleigh Curve by this equation E=K/t2d.t.e-t2/2td2 Here E is the effort required at time t.(engineers and staffs) K= Area under curve. It is also called Putnam- NORDEN-Rayleigh Curve or PNR curve. ![]() The IEEE Computer Society and the ACM, the two main. Norden Estimation: He studied the Staffing patterns of R & D projects and proposed that Staffing level patterns can be approximated by the 'Rayleigh Distribution Curve' which specifies that the relationship between applied effort and delivery time for software project. /rebates/&252fstaffing-level-estimation-in-software-engineering. Re: Introduction of Software Engineering-Staffing Level Estimation Software engineering is an application of a systemic, disciplinable, quantifiable approach to the design, development operation and maintenance of software and the studies of these approaches. Only a small number of engineers are required at the beginning of a. The estimate of future effort requirements is based on the managers experience of past projects and the application domain. Norden investigated the staffing pattern of R & D project. Putnam proposed that optimal staff develop on a project should follow the Rayleigh curve. Staffing level Estimation: NORDEN WORK Project manager has to figure out Staff Estimation after the effort required to develop a software has been determined.
