Current Software Development Scenario

Current Software Development Scenario

One-off development

Monolithic systems and increasing systems complexity

Working at low levels of abstraction

Process immaturity

Rapidly growing demand for software systems

ConclusionConclusion

“One-off development compounded with immature development processes (inconsistent use of tools, working at low abstraction levels, limited reuse and lack of explicit process structure) lead to cost overruns, delayed deliverables, unimplemented functionality, and even project cancellation.”

IS THERE ANY SMART WAY TO TACKLE THESE PROBLEMS???

What is Software Factory?What is Software Factory?

A software product line that configures extensible tools, processes, and content using a software factory template based on a software factory schema to automate the development and maintenance of variants of an archetypical product by adapting, assembling, and configuring framework-based components

Software Product Line???Software Product Line???

A Software Product line is a set of software-intensive systems sharing a common, managed set of features that satisfy the specific needs of a particular market segment or mission and that are developed from a common set of core assets in a prescribed way.

Improved product quality because core factory assets have already been tested and used in previous products and therefore have matured Flexibility in addressing the changing market demands because of clear application
