Manageability
Description
Attributes of software that bear on the effort needed to (re)establish its running status.
Indicators
1. control effort ratio
The ratio of effort put in controlling the software product (including maintenance) in man-hours to the number of hours the product is available to the users.
Source: QUINT
Scale: ratio
Validity: **
Protocol:
1. Determine the duration of the measurement period in order to achieve a sufficiently reliable measurement;
2. Register the amount of time needed to control the software product (including maintenance) during this period;
3. Register the availability of the software product in hours during this period;
4. Determine the ratio.
Note: Control effort can be hidden in user actions, therefore influencing this indicator.
