Models for software measurement fall into two major categories: probability models for reliability prediction and statistical models that use software quality metrics as predictors of quality. The former use historical failure data to estimate model parameters that are related to the initial failure rate and the rate of change of failure rate.

1. Software Life Cycle. Three main stages of a computer program: 1) Development. 2) Use. 3) Maintainance. As the names indicate, the development phase includes all the planning, writing, testing, and debugging of a computer program. When you are fairly certain that a program is usable, then you release it for use.

Evolutionary software development or ESD is being widely accepted as a lifecycle model . of choice for software development.This paper explores the concept of evolutionary . software development.Its features are contrasted with those of traditional software . development models like the waterfall model and advantages are observed.
The Software Life-Cycle Models
Software Lifecycle Models. Recalling from our first course, a software system passes through the following phases: Vision – focus on why. Definition – focus on what. Development – focus on how. Maintenance – focus on change. During these phases, a number of activities are performed. A lifecycle model is a series of steps through which ...

Later in the 1970's, two authors endeavored to define models based on theoretical grounds. Lawrence H. Putnam [10] based his Software Lifecycle Model (SLIM) on the NordenRayleigh curve plus empirical results from 50 U.S. Army projects.

Software Life-Cycle Models. The central idea of this chapter is the interplay between theoretical life-cycle models like the waterfall model and the rapid prototyping model and real-world life-cycle models like the iterative-and-incremental model. My objective in writing this chapter was to enable the student to select an appropriate life-cycle ...

A methodology is composed of one of the software development models used in conjunction with one or more techniques, i.e., methodology = model + technique(s). The techniques of prototyping, cleanroom, and object-oriented are ways to implement the waterfall, incremental, and spiral models.
