Software Project Management

Notes  Range of Application: By differentiating the estimation equations according to project
sizes and system types, the range of application for method COCOMO is a wide one. It is
also one of the few estimation methods offering-apart from the support for development
projects-support for the effort estimation of SWMM tasks as well (also by parametric
estimation equations) as for the estimation of the project duration.
 Tool Support: Computer-based support is required for Intermediate and Detailed
COCOMO, based on the quantity problem (differentiation of influence factors on phases
and sub products.

6.7.4 Modes

COCOMO can be applied to the following software project’s categories.

Organic Mode

These projects are very easy and have small team size. The team has a good application experience
work to a set of less than inflexible/rigid requirements. A thermal analysis program developed
for a heat transfer group is an example of this.

Semi-detached Mode

These are intermediate in size and complexity. Here the team has mixed experience to meet up
a mix of rigid and less than rigid requirements. A transaction processing system with fixed
requirements for terminal hardware and database software is an example of this.

Embedded Mode

Software projects that must be developed within a set of tight hardware, software, and operational
constraints. For example, flight control software for aircraft.

Caselet Nasscom Reiterates 16-18% Growth Estimate in IT Sector

Thiruvananthapuram Sept. 30:
The National Association of Software and Service Companies has stuck to its 16-18 per
cent annual growth estimate in the IT sector and termed the outlook positive.
Speaking to newspersons here after the Executive Council met in Kerala for the first time,
the Nasscom Chairman, Mr Rajendra Pawar, and the President, Mr Som Mittal, announced
the setting up of a regional chapter in the State.
