This chapter covers the issue of ensuring the implementation of a simulation study and the changes recommended as a consequence of simulation study results. It requires the use of a project management approach in addition to managerial and operational involvement in the implementation. The steps required to introduce a simulation modelling capability in the organisation are discussed. The use of simulation to address an organisational issue can be approached as a project activity, and the ideas of project management can be employed in order to manage the resources and skills needed to implement a simulation analysis. In order to use simulation successfully, a structured process must be followed. This section aims to show that simulation is more than just the purchase and use of a software package, but a range of skills is required by the simulation practitioner or team. These include project management, client liaison, statistical skills, modelling skills and the ability to understand and map out organisational processes.
