List of potential usability factors

The following usability factors were obtained by using a multi-method research approach and an article about the research was published in the International Conference on Software Process (ICSP 2008)[1].

	Usability Factor	Description
1	Understandable	A process description that helps process performers to understand the process and process engineers to evaluate the process
2	Easy to learn	A process description that requires a relatively small effort to learn
3	Well-structured	A process description that organises the information in a systematic way
4	Consistently presented	A process description that presents the information in a consistent manner
5	Effectively presented	A process description that uses an effective mix of text, diagrams, tables, etc.
6	Effectively supported	A process description that is supported by an effective mix of additional materials, such as templates, examples, and checklists
7	Tool-supported	A process description that is supported by tools to assist process communication and enactment
8	Complete	A process description that contains all the necessary information
9	Concise	A process description that is free from unnecessary detail
10	Unambiguous	A process description that has a single interpretation
11	Up-to-date	A process description that provides the latest process information that is relevant to the current project
12	Operable	A process description that is easy to put into practice
13	Navigable	A process description in which it is easy to find information
14	Tailorable	A process description that is easy to adapt to multiple project environments
