Project Estimation:
For an effective management accurate estimation of various
measures is a must. With correct estimation managers can manage and control the
project more efficiently and effectively.
Project estimation may involve the following:
- Software size
estimation
Software size may be estimated either in terms of KLOC (Kilo Line
of Code) or by calculating number of function points in the software. Lines of
code depend upon coding practices and Function points vary according to the
user or software requirement.
- Effort
estimation
The managers estimate efforts in terms of personnel requirement
and man-hour required to produce the software. For effort estimation software
size should be known. This can either be derived by managers’ experience,
organization’s historical data or software size can be converted into efforts
by using some standard formulae.
- Time
estimation
Once size and efforts are estimated, the time required to produce
the software can be estimated. Efforts required is segregated into sub
categories as per the requirement specifications and interdependency of various
components of software. Software tasks are divided into smaller tasks,
activities or events by Work Breakthrough Structure (WBS). The tasks are
scheduled on day-to-day basis or in calendar months.
The sum of time required to complete all tasks in hours or days is
the total time invested to complete the project.
- Cost
estimation
This might be considered as the most difficult of all because it
depends on more elements than any of the previous ones. For estimating project
cost, it is required to consider -
- Size of
software
- Software
quality
- Hardware
- Additional
software or tools, licenses etc.
- Skilled
personnel with task-specific skills
- Travel
involved
- Communication
- Training and
support
