Level of effort
An activity is an operation or process consuming time and possibly other resources. An individual or work team can manage an activity. It is a measurable element of the total project programme.
The term ‘level of effort’ can be used in relation to:
‘…a special activity type in programming software with unique qualities for duration. The software calculates the duration of a level of effort activity based on dates from its predecessor(s) and successor(s) rather than having a duration assigned to the particular activity. They are supposed to be used for support work, such as meetings, which occur during the timeframe of the predecessors and successors. In practice, they are sometimes also used in the older context of ‘hammocks’ but are not in fact a hammock.'
A hammock can be used to refer to an activity representing the period from the start of an activity to the completion of another. It is sometimes used as a way of summarising the duration of a number of activities in a programme as one single duration.
