Traceability
Description
Attributes of software that bear on the effort needed to verify correctness of data processing on required points.
Notes
Note: if the required point is only set at the end of the programming phase, this characteristic is essentially the same as accuracy.
Indicators
1. operation control effort
The amount of time that is lost while processing due to operation control activities, manually or automatically.
Source: QUINT
Scale: ratio
Validity: ***
Protocol:
1. Carry out the operation control activities, and determine the processing time needed for sub tasks;
2. Determine the time needed for the manual operation control activities;
3. Determine the portion of operation control time in relation to the total time of processing;
4. Operation control effort is the ratio of operation control time and normal processing time.
2. ease of operation control
The amount of effort needed to perform the operation control.
Source: QUINT
Scale: ratio
Validity: **
Protocol:
1. Determine the time needed for manual operation control;
2. Determine (1) in proportion to total processing time.
or:
Protocol:
1. Determine the time needed for manual operation control;
2. Determine the average length of time for each control point.
