4.2.3 Summative evaluation
As the name suggests, this type of evaluation is primarily concerned with making judgements about the effectiveness or impact of something, be it a discreet technology, system, project or programme. In other words, moving on from evaluating what is happening to study what has happened. The aim is to provide an analysis and conclusions as to the overall merit or worth of a programme or project. The emphasis when designing and conducting this type of evaluation is therefore on collecting data about outcomes or impacts. For obvious reasons, then, this type of evaluation is often referred to as outcome, outcome assessment or impact evaluation or assessment. An example would be where we are concerned with whether a technology has delivered the planned or promised benefits and thus whether outcomes justify continued support.
