Determine the indicator's value by using the following methodology:
1) Define what the core functions are, such as:
> holding regular meetings of the group members,
> guaranteeing certain proportion of female members,
> assigning clear responsibilities to every group member,
> regularly collecting money from water users based on a standardised tariff that is calculated based on cost-recovery of operation and maintenance,
> ensuring relevant and up to date records of income and expenditures,
> having functioning cooperation with an authority/ company who can ensure water source's repair,
> arranging water source's repairs within a certain time period,
> maintaining sufficient income that can cover standard operation and maintenance costs, and
> other functions as defined by the group's internal rules.
2) Set the minimum number of the core functions that need to be performed in order for the indicator to be met (for example, at least 7 out of 10 functions - 70%).
3) Assess (through interviewing the group members and key informants, review of records, observation, etc.) whether the water management group performs the functions.
4) Conclude whether the water management group performs the minimum number of the core functions; consider whether not meeting certain most crucial functions (for example, arranging repairs on time) should automatically lead to marking the group as "not meeting its core functions".
5) To calculate the indicator's value, divide the number of targeted water management groups performing at least the given % of their core functions by the total number of assessed groups. Multiply the result by 100 to convert it to a percentage.
