Study Notes

Systematic Software Reuse

One key benefit of adopting a design process based on systematic software reuse is the reduction of development costs and time.

Application System Reuse

Application system reuse refers to the reuse of entire software applications or systems in software engineering.

Not-invented-here Syndrome

The 'Not-invented-here syndrome' refers to the reluctance of developers to use existing software components or reuse code because they were not created in-house.

Tool Support for Software Reuse

A common problem associated with lack of tool support for software reuse is the difficulty in finding and integrating reusable components.

Maintenance Costs

The absence of source code for reused software can increase maintenance costs because it can be difficult to modify or debug the reused code.

Component Reuse

Component reuse refers to the reuse of software components, such as objects, modules, or subsystems, in the context of software engineering.

Original Software vs. Reused Software

Writing original software is often seen as more challenging than reusing other people's software because it requires more creativity, expertise, and effort.

Reusable Component Library

One of the problems associated with populating a reusable component library is the difficulty in defining a common interface or standard for the components.

Upper Management Support

Upper management support is a crucial factor for systematic software reuse, as it requires a strategic decision to invest in reuse and a commitment to change the development process.

Component Search

Engineers must be reasonably confident of the quality and reliability of the components before they include a component search in their normal development process.

Legal Factor

A potential problem associated with the legal factor influencing reuse is the risk of intellectual property infringement or licensing issues when reusing software components.

Reuse Costs

According to Favaro's study, some artifacts need to be reused at least 3-5 times to recoup the extra cost of developing reusable components.
