Every business wants to be able to reduce its overheads as much as possible in order to improve the profitability of its products or services. Also, it is important to make sure that the processes employed in a business are streamlined so that time or resources are not wasted on unnecessary stages of a project or activity. Though this is easy to state, it is not so easy to find out as in many businesses these processes are extremely complex.
In order to fully understand everything that goes on in your business you must perform a full, in-depth analysis of your business’s processes and procedures right from the beginning of a process up until a product or service is received by your customers. By carrying out this research you can learn about what areas of the business take more resources and at what stages of the process are there more conflicts or inefficiency. This research is called process modelling as it serves to define the process of actions within a business.
Process modelling has been around since the very late 19th Century when the first process models were created in the form of Gantt charts. These charts were seen as revolutionary at the time and are even now a widely used tool in process modelling and work breakdown structure (WBS) charts. Over the years many more types of charts have been developed including the flow chart, the functional flow block diagram, the PERT diagram and the control flow diagram. When used together, these models provide a clear view of the processes employed in business.
The reason business management choose to initiate process modelling is so that data on work processes is simple to understand, being in a concise and clear manner. Process models are bar charts, graphs and other visual images that can be read and understood within seconds, as opposed to the minutes or even hours it may take to read a detailed report containing the same information. This assumes, however, that the most suitable process model is used as different models and diagrams are better at displaying certain types of data than others.
Within large multi-national corporations on extremely large scale projects that take years to complete steps within the project and use up the resources of thousands of employees it can be overwhelming for a company to take on the task of retro-analysing the project in-house. In this situation it is often best to utilize the resources of another party, outsourcing the task to a company that specialises in this task, therefore increasing your available resources and reducing the time until completion of the process modelling.
