Most Significant Change (MSC) methodology is a technique with a high level of involvement from stakeholders
Stakeholders participate in the decisions about what changes are recorded and reported. They are also involved in analysing the resulting information. The method involves the generation and collection of a range of significant change impact stories, with the most significant of these being selected for use. Further details are provided in Rick Davies and Jess Dart’s guide.

Value can be defined as "the importance that stakeholders (funding institutions, politicians, the public, users, staff) attach to libraries and which is related to the perception of actual or potential benefit.

Output and outcomes can lead to impact and finally to value.” - Methods and procedures for assessing the impact of libraries
