Formal estimation model: The quantification step is based on mechanical processes, e.g., the use of a formula derived from historical data. Combination-based estimation: The quantification step is based on a judgmental and mechanical combination of estimates from different sources. Below are examples of estimation approaches within each category.
An estimated software size at project completion and organizational process productivity is used. Plotting effort as a function of time yields the Time-Effort Curve. The points along the curve represent the estimated total effort to complete the project at some time. One of the distinguishing features of the Putnam model is that total effort ...
The first meeting is the kickoff meeting, during which the estimation team creates a work breakdown structure (WBS) and discusses assumptions. After the meeting, each team member creates an effort estimate for each task. The second meeting is the estimation session, in which the team revises the estimates as a group and achieves consensus.
The Intermediate Cocomo formula now takes the form: E = a i (KLoC) b i (EAF) where E is the effort applied in person-months, KLoC is the estimated number of thousands of delivered lines of code for the project, and EAF is the factor calculated above. The coefficient a i and the exponent b i are given in the next table.
In project management (e.g., for engineering), accurate estimates are the basis of sound project planning. Many processes have been developed to aid engineers in making accurate estimates, such as Analogy based estimation; Compartmentalization (i.e., breakdown of tasks) Cost estimate; Delphi method; Documenting estimation results; Educated ...
There are several cost, schedule, and effort estimation models which use SLOC as an input parameter, including the widely used Constructive Cost Model series of models by Barry Boehm et al., PRICE Systems True S and Galorath's SEER-SEM. While these models have shown good predictive power, they are only as good as the estimates (particularly the ...
The analysis effort method is a method for estimating the duration of software engineering projects. [1] It is best suited to producing initial estimates for the length of a job based on a known time duration for preparing a specification. Inputs to the method are numeric factors which indicate Size (S), Familiarity (F) and Complexity (C).
The effort measure translates into actual coding time using the following relation, Time required to program: = seconds; Halstead's delivered bugs (B) is an estimate for the number of errors in the implementation.
