Software Development and Management

It is a basically method to analyze the task involved in completing a given project, especially the time needed to complete each task, and identifying the minimum time needed to complete the total project.

Here, strategic planning data and planning models are added to the information system.

It means that the system, product or service is ready on demand to perform a mission when tasked.

This model is useful in proof of concept or situations where requirements and user's need are unclear or poorly specified.

These include status review meetings and design and code inspections.

It is a hierarchic decomposition of a project or major activity into successive levels.

This model accommodates life cycle evolution, growth and requirement changes.

Each component of the software job is separately estimated and the result aggregated to produce an estimate for the overall job.

It can be used as a management tool as an early warning system to detect deficient or endangered progress.

The project is developed in a familiar, stable environment, and the product is similar to previously developed products.

These metrics are indirect measures of software which focus on functionality and utility.

Individual functional applications are planned separately consisting of transaction processing, updating of files and simple reports.

These decisions are unstructured, occasional of high consequence, complex and involve major commitments?

The approach is to construct a quick and dirty partial implementation of the system during or before the requirement phase.

The modular approach involves breaking down a complex system into smaller, independent, manageable modules or components. Each module can be designed, implemented, and tested separately, making the overall system development, analysis, and maintenance more systematic and less error-prone.
