Study Notes

Software Development

Software should be produced at a reasonable cost, in a reasonable time, and with good quality.
Industrial-strength software is very expensive.

Efficiency

Efficiency is the capability to provide appropriate performance relative to the number of resources used.

Project Management

Concerned with ensuring software is delivered on time and on schedule.
Involves planning, scheduling, supervising, and controlling project activities to meet required standards.

Maintenance Types

Corrective Maintenance: fixing errors or making changes due to previously unknown problems.
Adaptive Maintenance: modifying software to adapt to changes in the external environment.
Perfective Maintenance: improving software performance or modifying it to meet new user requirements.
Preventive Maintenance: preventing system deterioration through processes like reverse engineering and re-engineering.

Iterative Delivery Process Model

A model where the system is built incrementally, with each iteration delivering a working software system providing value to the end user.
Requirements are determined at the start of each iteration, and then designed and developed.
The iteration ends with the delivery of a working software system providing some value to the end user.
