Eliminate unnecessary activities
Eliminate non-value adding practices

A common way of regarding a activity as unnecessary is when it adds no value from a client's point of view. Typically, control activity in a workflow do not do this; they are incorporated in the model to fix problems created or not elevated in earlier steps. Control activities can often be found back as iterations and reconciliation tasks.
The heuristic is widespread in literature, for example see Peppard and Rowland (1995), Berg and Pottjewijd (1997), and Van der Aalst and Van Hee (2002). Buzacott (1996) illustrates the quantitative effects of eliminating iterations with a simple model.
The aims of this heuristic are to increase the speed of processing and to reduce the cost of handling a case. An important drawback may be that the quality of the service deteriorates.
Foundational free Patterns
Combine small activities into composite activities
Determine whether activities are related to the same type of case and, if necessary, distinguish new business processes
If capacity is insufficient, consider increasing the available number of resources
Minimize numerical involvement
Too many cooks spoil the broth
Move activities to more appropriate places
Consider the division of a general activity into two or more alternative activities
Collect similar work items and work in batches
Replace underlying resources with eco-friendly alternatives
Performance-based task assignment
Allocate tasks based on past performance: execution time and success
