When choosing to introduce any people/hr tech solution, remember the 5 step flywheel:

Step 1: Identify what are the business problems you are looking to solve

Step 2: Translate them into business requirements to be solved

Step 3: Build the tech specs needed to solve these requirements, with tangible outcomes and outputs

Step 4: Implement the best suited tech solution

Step 5: Iterate. Business landscape changes and with it, requirements.
