Any cost estimation model can be viewed as a function that outputs the cost estimate. The basic idea of having a model or procedure for cost estimation is that it reduces the problem of estimation of determining the value of he “key parameters” that characterize the project, based on which the cost can be estimated.

After the implementation phase, the testing phase begins. Testing of software is critical, since testing determines the correctness, completeness and quality of the software being developed. Its main objective is to detect errors in the software.

In a top-down implementation, the implementation starts from the top of the hierarchy and proceeds to the lower levels. First the main module is implemented, then its subordinates are implemented, and their subordinates, and so on.

In time boxing model, development is done iteratively as in the iterative enhancement model. However, in time boxing model, each iteration is done in a timebox of fixed duration. The functionality to be developed is adjusted to fit the duration of the timebox. Moreover, each timebox is divided into a sequence of fixed stages where each stage performs a clearly defined task (analysis, implementation, and deploy) that can be done independently. This model also requires that the time duration of each stage is approximately equal so that pipelining concept is employed to have the reduction in development time and product releases.

Once the software is developed it should be tested in a proper manner before the system is delivered to the user. For this, two techniques that provide systematic guidance for designing tests are used. These techniques are discussed here.

Programming refers to the method of creating a sequence of instructions to enable the computer to perform a task. It is done by developing logic and then writing instructions in a programming language. A program can be written using various programming practices available. A programming practice refers to the way of writing a program and is used along with coding style guidelines. Some of the commonly used programming practices include top-down programming, bottom-up programming, structured programming, and information hiding.

The software engineering deals with three basic types of entities – processes, project, and products. A software process is a method of developing software. A software project is a development project in which a software process is used. And software products are the outcomes of a software project.

To assess the quality of the engineered product or system and to better understand the models that are created, some measures are used. These measures are collected throughout the software development life cycle with an intention to improve the software process on a continuous basis. Measurement helps in estimation, quality control, productivity assessment and project control throughout a software project. Also, measurement is used by software engineers to gain insight into the design and development of the work products. In addition, measurement assists in strategic decision-making as a project proceeds.

Methods for Monitoring a Project

          Time sheets

Once project development commences, the management has to track the progress of the project and the expenditure incurred on the project. Progress can be monitored by using the schedule and milestones laid down in the plan.

A development process consists of various phases, each phase ending with a defined output. The phases are performed in an order specified by the process model being followed. The main reason for having a phased process is that it breaks the problem of developing software into successfully performing a set of phase, each handling a different concern of software development.
