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.
