The best way to get good at something is to do it. Sales people do mock calls dozens of times before they talk to a customer. Navy SEALs "train like they fight" so they are prepared for the worst.
It might not be nearly as grave as going to war, but buying HR Tech can be quite daunting and full of as many pitfalls.
The HR professionals who are lucky enough to have been through a few HR Tech buying cycles have the scar tissue and learnings to be effective purchasers of People software.
However, you don't need to be 20 years into your career before you get good at buying HR software!
In the past, most HR software buying was done in the context of multi year planning cycles. It took 6-24 months to procure the right solution, another 3-18 months to implement, and 12 months later you'd start looking for the next solution to buy.
SaaS, freemium products, and the rise of product led growth have allowed companies to purchase tools in a light weight try before you buy way. Many vendors have a cheap (or free) offering. And, this number is growing quickly.
The ability to try products means that People teams, and individual People leaders, don't have to wait for the next time you buy a core tool like an ATS or HRIS to get reps on discovering/buying/implementing tools.
You don't need cross functional internal buy-in, nor big budgets, to start using a free video interview solution today.
You don't need c-level sign off to experiment with an ATS that has a free trial, an assessment tool with a free tier, or a recognition platform that allows small teams to get value for cheap as they grow.
While these solutions may not be a game changer in your organization, they give you very valuable repetitions on the buying process. And, most of these free solutions can scale at very large companies if you happen to like the product.
Buying new HR Tools is hard. There are many steps to buying HR tech, and many places where you can fall down. Having a few reps, even if it's for very small projects, can give you the lessons you need to succeed when you have a more daunting project.
