Read more about our – Estimating Software Projects If the estimate is unrealistically low, the project will be understaffed from its outset and, worse still, the resulting excessive overtime or staff burnout will cause attrition and compound the problems facing the project. Overestimation is not the answer.

Indeed, overestimating a project can have the same effects as any other inaccurate estimate. Software Estimation. The definition of the verb to estimate is to produce a statement of the approximate value of some quantity.

Estimates are based upon incomplete, imperfect knowledge and assumptions about the future. Most importantly, however, all estimates have uncertainty. There is no such thing as a precise, single-value estimate. Managers should always ask how large the uncertainty of an estimate is! A manager can use the size of this uncertainty in conjunction with other factors such as perceived risks, funding constraints, and business objectives to make decisions about a project.

1.Population:By taking a static count of Object Oriented Entities,exa:Classes and Operations. 2.Volume:The Population measured but are collected dynamically at given instance of time.(the poulation may be changed after multiple uses of diferent entities so its called Dynamically) 3.Length:A chain of interconnected design elements such as:inheritance tree with its length.

4.Functionality:indirect indication of the value delivered by aplication.(software size depends on user is required functionality of application or a Software. 1.Population:By taking a static count of Object Oriented Entities,exa:Classes and Operations.2.Volume:The Population measured but are collected dynamically at given instance of time.(the poulation may be changed after multiple uses of diferent entities so its called Dynamically)3.Length:A chain of interconnected design elements such as:inheritance tree with its length.4.Functionality:indirect indication of the value delivered by aplication.(software size depends on user is required functionality of application or a Software. A Software Engineer does many things (I  know as I was one for 14 years and before that worked with them as  a Hardware Technician for 16 years).

The main thing that a Softw are  Engineer does is writing documentation for other Engineers and for  delivery to the Customer, to describe the software design and  explain how the software is installed and used, etc. Roughly at  least 2/3s of a Software Engineer's time is spent on that, so  writing skills are a very high priority. The computer science discipline concerned with developing large applications.

Software engineering covers not only the technical aspects of building software systems, but also management issues, such as directing programming teams, scheduling, and budgeting. Software Engineering is an approach to developing software that attempts to treat it as a formal process more like traditional engineering than the craft that many programmers believe it is.
