A work breakdown structure (WBS), in project management and systems engineerin decomposition of a project into smaller components. It defines and groups a project helps organize and define the total work scope of the project. The Work Break down structure should include any and all tasks that are within the estimated. 1).Break sizing into smaller, easier to estimate tasks a.Decompose the test project into phases.

Three Point Estimation Three Point Estimation technique is based on statistical methods, and in particular, the Normal distribution. In Three Point Estimation we produce three figures for every estimate: a = the best case estimate m = the most likely estimate

b = the worst case estimate These values are used to calculate an E value for the estimate and a Standard Deviation (SD) where: E = (a + (4*m) + b) / 6 SD = (b - a)/6 E is a weighted average which takes into account both the most most optimistic and pessimistic estimates provided and SD measures the variability or uncertainty in the estimate. To produce a project estimate the Project Manager: Decomposes the project into a list of estimable tasks, i.e. a Work Breakdown Structure Estimates each the E value and SD for each task. Calculates the E value for the total project work as E (Project Work) = Σ E (Task) Calculates the SD value for the total project work as SD (Project Work) = √Σ SD (Task) 2 We then use the E and SD values to convert the project estimates t o Confidence Levels as follows: Confidence Level in E value is approximately 50% Confidence Level in E value + SD is approximately 70% Confidence Level in E value + 2 * SD is approximately 95% Confidence Level in E value + 3 * SD is approximately 99.5% Enter the a,m, and b values for each Task into columns C,D and E. The E and SD values for each task will be calculated and displayed in columns F and G. A task estimate with at least 95% confidence and the required task booking value is calculated and displayed in columns H and J. Based on the individual task estimates the E value and SD for the project will be calculated and displayed as will the overall work estimate for the project

Delphi & Size based estimation This Estimation technique is a mixture of Delphi and Size based, taking into account prev history and experience and three figures (Best, Optimized and worst)for every estimate.
