Startups must also avoid Reactive Employee Resource Types that reflect a haphazard approach to building a talent pool. It is tempting to outsource everything and “run lean” until revenue justifies hires, but key hires are necessary to get passionate commitment and build skills over time. On the other end of the spectrum, hiring full-time employees to do everything is too costly: startup needs change too much to anticipate every skill that will serve current and future workforce challenges. Just reacting to product development and customer service demands creates additional human debtbergs. The staffing strategy should include a plan for which functions need full-time, dedicated talent, which can get by with part-timers, and which would do best with outsourced talent. A startup should have metrics in place that trigger converting a part-time to full-time employee—for example, when there are ten customers or $100,000 in monthly recurring revenue, employee X can convert from part- to full-time.
