A good programme design will consider how to monitor and evaluate during and after the implementation phase (in itinere and ex post). It will therefore decide what are the indicators and what are the sources of information for judging the efficiency, the effectiveness and the impact. Information sources may be independent from the programme/project management team and the organization. Programme designers will consider the standard methods of collecting and analyzing data and will adopt those that are seen as most suitable. Eventually a new approach may be proposed.
