COCOMO MODEL PPT SOFTWARE
Setting mixed investment strategies to improve organization's software capability, via reuse, tools, process maturity, outsourcing, etc. Deciding on or negotiating tradeoffs among software cost, schedule, functionality, performance or quality factors. It has new cost drivers, new line counting rules, and new equations. You'll use it after you've developed your project's overall architecture. It uses a small set of new Cost Drivers, and new estimating equations. You can use this model to get rough estimates of a project's cost and duration before you've determined it's entire architecture. The original COCOMO model has been very successful, but it doesn't apply to newer software development practices as well as it does to traditional practices. It provides more support for modern software development processes and an updated project database. The model uses a basic regression formula, with parameters that are derived from historical project data and current project characteristics.
A very rapid build-up of people often correlates with schedule slippage.Login Now. The more people who work on the project, the more total effort is usually required. The number of people working on a project varies depending on the phase of the project. The time required is independent of the number of people working on the project. This computation predicts the nominal schedule for the project. Overall, the model reveals the importance of staff experience in software development.
COCOMO MODEL PPT UPGRADE
Option C upgrade memory has a lower cost saving but very low risk. Embedded spacecraft system Must be reliable Must minimise weight number of chips Multipliers on reliability and computer constraints Cost components Target hardware Development platform Development effort. Project attributes Concerned with the particular characteristics of the software development project. Personnel attributes Multipliers that take the experience and capabilities of the people working on the project into account. Computer attributes Constraints imposed on the software by the hardware platform. The client has not defined the process to be used and has not allowed time for risk analysis.
COCOMO MODEL PPT CODE
The code size is estimated as: Number of lines of new code to be developed Estimate of equivalent number of lines of new code computed using the reuse model An estimate of the number of lines of code that have to be modified according to requirements changes.
COCOMO MODEL PPT HOW TO
AAM is the adaptation adjustment multiplier computed from the costs of changing the reused code, the costs of understanding how to integrate the code and the costs of reuse decision making. This then adjusts the size estimate for new code. White-box reuse where code is modified.Ī size estimate equivalent to the number of lines of new source code is computed. There are two versions: Black-box reuse where code is not modified. Used once the system architecture has been designed and more information about the system is available. Used to compute the effort of integrating reusable components. Used when requirements are available but design has not yet started. Used when software is composed from existing parts. Software Project Cost Estimates Using COCOMO II Model Since its formulation, there have been many changes in software engineering practice and COCOMO 2 is designed to accommodate different approaches to software development.
