Planning Conducting Reporting
The stages associated with planning the review are:
• need
• Development
•
• Selection
• assessment
• extraction monitoring
• synthesis
The stages associated with conducting the review are:
.
need for a systematic review
CRC [12] suggests the following checklist:
• objectives
• restrictions
• inclusion/exclusion criteria
• assess the quality
• extracted
• synthesised
combined
• conclusions flow evidence
.
need for a systematic review
From a more general viewpoint, Greenlaugh [9] suggests the following questions:
•
•

The Research Question
In software engineering, questions can be adapted to software engineering issues as follows:
< Question Types >
• effect
