How to do longitudinal/recurring data monitoring

Longitudinal / Recurring monitoring with mWater 
Why Longitudinal / Recurring monitoring? 
Longitudinal / Repeat monitoring involves repeated observation of the same variables and is key to be able to track changes in the status of an object (e.g. assets such as pump, tank, pipe) or to track changes in key performance indicators (such as functionality, water quality, tariff recovery etc).
This is a fundamental function of an effective management information system where data is regularly collected to inform periodic decision making (e.g. planning, budgeting, operations etc)

How to structure longitudinal/ recurring monitoring on mWater?
To be able to track changes regularly you need to include a unique identifier in your data collection for the specific object you are tracking (e.g. village name, infrastructure ID etc)
OPTION 1 (recommended): mWater has a key function which support longitudinal / recurring monitoring: SITES. These are locations that you want to monitor over time.
SITES on mWater include communities, schools, health clinics, water points, water systems etc
Sites are permanent features of mWater and existing SITES can be linked to by different users.

If you want to monitor a set number of questions or indicators for the same SITE(S) you can create a SURVEY which contains these questions and the relevant SITE(S) question

OPTION 2: If you don't want to use SITES you can do longitudinal monitoring you can use a dropdown list of possible unique identifier for the specific object you are tracking (e.g. list of school names) that the data collector can select when filling the surveys.
For long lists, consider using a Cascading reference question to guide a user from, for example, a region to a district and then a village.
How to collect longitudinal/recurring data on mWater?
 After developing your survey, deploy this to your data collectors groups and collect the data. The SITE question of the survey will prompt you to LINK to an existing SITE or create the new SITE if this does not exist yet.
You can then use the same SURVEY to collect data  from the same SITE multiple times in different periods (e.g. yearly, monthly etc). For this, you can use the same SURVEY deployment or create a different deployment at every data collection cycle.
How to visualise longitudinal/recurring data on mWater?
To visualise the longitudinal data over different time periods, you can generate on console or dashboard the following:
