Software Engineering and Information Systems

These include status review meetings and design and code inspections.

Work is often coordinated electronically, while system enable information to more easily move around the organization and decentralizing decision making.

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

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

It is invoked to equate the cost estimate to the available resources.

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.

The engineering process of understanding, analyzing and abstracting the system to a new form at a higher abstraction level.

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

Here, the line of authority flows vertically from the top most executive to the lowest subordinates.

Here, all activities in the organization are grouped together according to basic functions like production, marketing, finance, human resource etc..

The purpose of this system is to record, process, validate and store operations that take place in various functional areas of business.

Information which is generated at regular intervals of time.

These systems are well integrated systems that store, retrieve, and process different types data such as text, graphics, images, full motion video, audio and animation.

Distributed databases help to store the data where it is most needed or used, and help to customize the data to meet the needs of individual business units.

This information is available in some written form, microfilms, magnetic tapes, floppy disks etc..

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

It promotes flexibility and data advisability, since data elements at a lower level can be accessed without accessing the data elements.

The sales analysis, accounts receivables system and market research analysis are the example of Information Analysis System.

This DSS function helps managers to be proactive, rather than reactive, in their decision making.

Key decisions are made at the top and filter down through the organization.

These models have clarity to the extent that each of them has a set of assumptions, which must be true in real life.

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

It helps in scheduling the activities of a project, but it does not help in identifying them.

The actual cost must corresponds to whatever was budgeted for the planned value and the earned value.

This method involves reasoning by analogy with one or more completed projects to relate their actual costs to an estimate of the cost of a similar new project.

The examination and alteration of an existing subject system to reconstitute it in a new form.

It is a branch of computer science whose goal is to design and develop machines that emulate human brain power.
