Sources for human resources can be varied, not just directly employed employees. In such cases there will be contracts.
Contracts will also exists for other areas such as:
- software development
- software maintenance
- network provision
- software licences
Contract costs can vary greatly and require managing with help from KPIs and performance metrics.
Performance metrics may be complicated i.e. to use quality as a metric in software development requires the definition of quality.
Software development can often take years to complete delivery therefore time scales and criteria for payment will need to be designed and agreed by both parties.
