Software Properties and Pattern Usage

(1) (2) (3) (4) (5)

Patterns support the development of software with specific qualities.

Patterns help to develop complex and heterogeneous software architectures.

Patterns improve the documentation of the software development process.

Patterns improve extensibility, portability and reusability of software.

Use of patterns results in a clearer design.

Patterns guarantee the retention of the original design by restricting changes in maintenance.

It is difficult to recognise a pattern in source code although using patterns developed the code.

Patterns increase runtime costs, by introducing an additional layer of abstraction.

Individual Experience with Patterns

(1) (2) (3) (4) (5)

Patterns improve communication in the development process between the individuals who are familiar with the respective patterns.

Patterns support the integration of new software developers.

It is difficult to decide which pattern is the best for a specific problem.

Pattern descriptions are insufficient for a direct application.

Pattern mining is a human-intensive task.

Patterns are difficult to learn.

Patterns lead developers to think they know more, than they actually do.

Patterns in the Software Process

(1) (2) (3) (4) (5)

Object-oriented patterns help in the transition to object-oriented technology.

Patterns increase the predictability of decisions in analysis, design and implementation and increase standardisation of models and program code.

In contrast to other reuse approaches patterns have to be implemented again and again.

Patterns rely on the experience of previous projects. They do not generate new solutions.

Costs and Benefit of Patterns

(1) (2) (3) (4) (5)

Use of patterns is not linked to high costs.

By using patterns, one can avoid costs related to the development of a new solution.

Patterns reduce the risk inherent in software development projects.
