Further, from fig, it can be observed that the development time is roughly the same for all three categories of products. This reduces the time to complete the project. The parallel activities can be carried out simultaneously by the engineers.

From fig it can be observed that the development time is a sub linear function of the size of the product, i. The development time versus the product size in KLOC is plotted in fig. Thus, the effort required to develop a product increases very rapidly with project size. From fig, we can observe that the effort is somewhat superliner in the size of the software product. Some insight into the basic COCOMO model can be obtained by plotting the estimated characteristics for different software sizes.ДЇig shows a plot of estimated effort versus product size.

For the three classes of software products, the formulas for estimating the effort based on the code size are shown below.ДЇor the three classes of software products, the formulas for estimating the development time based on the effort are given below. Effort is the total effort required to develop the software product, expressed in person months PMs. Embedded: A development project is treated to be of an embedded type, if the software being developed is strongly coupled to complex hardware, or if the stringent regulations on the operational method exist.ДЇor three product categories, Bohem provides a different set of expression to predict effort in a unit of person month and development time from the size of estimation in KLOC Kilo Line of code efforts estimation takes into account the productivity loss due to holidays, weekly off, coffee breaks, etc. Team members may have finite experience in related systems but may be unfamiliar with some aspects of the order being developed. Semidetached: A development project can be treated with semidetached type if the development consists of a mixture of experienced and inexperienced staff. Organic: A development project can be treated of the organic type, if the project deals with developing a well-understood application program, the size of the development team is reasonably small, and the team members are experienced in developing similar methods of projects.Д®xamples of this type of projects are simple business systems, simple inventory management systems, and data processing systems.

To determine the initial effort E i in person-months the equation used is of the type is shown below. The initial estimate also called nominal estimate is determined by an equation of the form used in the static single variable models, using KDLOC as the measure of the size.
