Said above is a short scope definition for the project provided by the company. Since the project is small, the elaboration phase (or detailed design phase) is not necessary.Build components for this project using Java.Transfer existing SQL Server database (~1 GB) hosted on Windows to PostgreSQL data end hosted on Linux.The customer has the following preferences: The company has already made work on inception phase, and provided the document describing the project concept. The content of this article targets cost estimation perspective of the latter project. As soon as the scope of this task is broadly defined as such, it is sliced into a separate project. As part of this project, a database provider that exposes simple interfaces to UI programmer and hides complexities of the data layer should be build. Sample Project Description and ScopeĪ bioinformatics company, providing advanced methods for data mining of genetic information, intends to construct a distributed application for analysis and navigation of biological networks. My objective is to describe in a simple way basic cost estimation steps, tools and assumptions, having a real project in mind, and supplying only necessary details on the project itself. The article is intended for those who are new to project cost estimation techniques, and those who would like to have a feedback on COCOMO II model. Semi-detached: Time of Development = 2.5 (Effort)^ 0.35 MonthsĮmbedded: Time of Development = 2.5 (Effort)^ 0.This article provides a sample of COCOMO II cost estimate for a real project, and concentrates on outlining basic how-to when project manager needs some advice on making simple cost estimates and tools that can be used. Organic: Time of Development = 2.5 (Effort)^0.38 Months Semi-detached: Effort = 3.0 (KLOC)^1.12 PM Where, a1,a2,b1,b2 are constants for each category of software products Estimation of Effort Time of Development = b1 x (Effort)^b2 Months The basic COCOMO estimation model is given by following expressions:Įffort = a1 x (KLOC)^a2 PM (person Month) The basic COCOMO model gives an approximate estimate of the project parameters.
