Model the process
Business process modeling is drawing out the activities in a process and how they relate to each other, step-by-step. In most cases, you start with an existing process and work to improve it. That leads to two models; the as-is model and the to-be model. You need to identify and assess current as-is business processes. Once you’ve done that, you can plan improved to-be business processes.
Your BPM model should show natural breakpoints to segment and implement steps. The transition of an activity from one department to another is one such breakpoint. For example, if a process passes an activity from HR to payroll, implement and test the HR processes, then the payroll processes, and then the transition from HR to payroll. For each step, you need to optimize, test, and analyze.
Modeling was done by hand in the past. You may have seen this done with sticky notes being moved around on a board. Today, you can use a business management platform like Pipefy to help you do the modeling.
BPM is all about making processes more efficient and effective. This requires you to model the entire process, but you should refrain from implementing changes to all of it at once. Mistakes and setbacks are inevitable when tinkering with processes, so you should try to make limited, discrete improvements to one or just a few processes at a time. This allows you to methodically analyze results and optimize the process one step at a time as opposed to making a drastic overhaul and hoping for the best.
