In some cases, project managers may have spreadsheets containing data on individuals allocated to a site once the development is underway or complete.
These additional sources of data can be useful where occupants are not beneficiaries (as when non-qualifiers were allocated to subsidy units in the case of informal settlement upgrading projects) or where HSS records are not accurate (for instance, HSS data may not have been updated when beneficiaries were removed from the project).
Before using this data, the housing authority should establish how it was collected, how well it was maintained and how accurate it is.
There are often discrepancies between the data on project manager spreadsheets and the data in the HSS. Resolving discrepancies can be time consuming. Municipalities or provinces may therefore prefer to reference project manager data only where a dispute exists or where other data needs to be validated, and primarily rely on HSS records.
