Organisational mining is a class of techniques that comes under the field of process mining, used for understanding the relationship between various resources acting in an organisation. An event log is a record of activities being executed, can contain additional information on the resources performing the actions. By extracting knowledge about the actual behaviour of resources participating in business processes from event logs, organisational models can be constructed, which facilitate the analysis of the de facto grouping of human resources relevant to process execution.[1]
Sociometry, also referred to as sociography, refers to methods presenting data on interpersonal relationships in graph or matrix form.[2] By analysing the execution pattern of the resources it is possible to mine a social network representing working relations between them.
Overview[edit]
Organisational mining combines people/resources in the organisation and ties it together with the analysis of processes and their behaviour. Missing resources, change in shift timing, change of teams, etc. can cause delays and bottlenecks in the execution of processes. Processes, people, roles and other organisational entities are intertwined and cannot be viewed in isolation. Hence organisational mining provides various techniques to understand the involvement of people in the processes.
- Handover of work: This metric helps in understanding the parts of the processes that are being handed over from one person to another. It also allows us to understand is there is any deviation in the handover that was supposed to happen.
- Sub-contracting of work: This metric helps in understanding what parts of processes are handed over by one person to another, only to take it back later and finish the process execution. This may indicate the close collaboration between people and an improvement in the area might promote process efficiency.
- Joint-work: This metric helps in understanding the persons responsible for the execution of similar work, in the sense that they all belong to the same team/ same level of proficiency.
The above mentioned techniques are used to construct social networks, which are essentially graphs that indicate how people work together.
Social networks - An example[edit]
An event log containing the resource attribute along with the timestamp and case ids can be used to analyse and create handover of work matrix. If a resource John executes an activity before another resource Jane, then we can conclude that John is handing over the work to Jane. Handover of work matrix shows the degree of work handover between the resources. Using handover of work matrix and footprint based matrix, it is possible to derive a social network.
Consider an event log with resource attribute:
In this event log, the Resource "Sara" is handing over work to "Pete" 0.33 times on an average. Resource "Mike" is handing over work to "Sean" 1 times on average. Using these numbers, a handover matrix can be constructed that looks as follows.
Using the above matrix, and the footprint matrix created using the event log we can create a social network.
