Short answer: an applicant tracking system (ATS) manages candidates until they are hired; a learning management system (LMS) delivers and tracks training; a workforce development system defines what each role needs and connects hiring, onboarding, training and career development to that definition on one employee record.

Side-by-side comparison

Question	ATS	LMS	Workforce development system
Main job	Track applicants and hiring stages	Deliver and track courses	Define each role, then hire, onboard, train and develop against it
Starts when	A job opens	A course is assigned	A seat is planned on the org chart
Stops when	Someone is hired	The course is completed	It does not stop; the same record follows the employee
Measures	Time in stage, sources	Completions	Skills against the role, before and after hire
Who uses it	Recruiters	L&D, employees	HR, talent acquisition, L&D, operations leaders

Where the gaps usually are

Each tool can work well on its own. Problems show up at the handoffs: the job description is rewritten from an old template, candidates are scored on different questions by different interviewers, onboarding begins again in another tool once someone is hired, and training is assigned to everyone rather than to measured gaps. LinkedIn’s 2025 Workplace Learning Report found that only 36% of organizations are fully committed to career-driven learning, which is harder to deliver when hiring and development live in separate systems.

Do you need all three?

Not necessarily. A workforce development system can cover applicant tracking and training itself, or sit alongside tools you already like. The question to ask is simpler: does every part of your process work from the same definition of each role?

Frequently asked questions

Will a workforce development system replace our ATS?

It can cover what an ATS does, but you do not have to replace a system that works for you. Many companies start with one role or one site.

What about our existing training content?

Content you already own can be loaded and assigned based on measured gaps, rather than to everyone.

Who should own it?

Usually HR or talent leadership, with operations leaders involved, because the role definitions come from the work itself.
