Growth and Career Development

People don't just want a paycheck — they want to get better at what they do and go somewhere with their careers. Supporting that growth is one of the most powerful things an organization can do, and one of the most neglected: when people stop growing, they leave. Investing in people's development isn't charity or a perk; it's how you build a more capable team and keep good people, because growth and retention are deeply linked. For technical leaders, developing people is among the highest-return investments available.

Growth and career development — helping people improve their skills and advance their careers — is central to developing people and keeping them. This post covers why growth matters (for people and the organization), how to support development, the growth-retention link, and career development. It builds on feedback (feedback drives growth) and connects to retention (the next post). Investing in people’s growth builds a more capable team and keeps good people — a high-return, often-neglected investment.

Why growth matters

Growth — people improving their skills and advancing — matters deeply to both people and the organization, making supporting it high-value:

Growth matters deeply — people want it (a core motivation), it builds a more capable team (compounding capability), and it’s a win-win for people and organization — yet it’s often neglected, making supporting it high-leverage. How to actually support development is the practical question.

How to support development

Supporting people’s development involves challenge, learning, feedback, and opportunity — the ingredients of growth:

Supporting development means giving challenging/stretching work (grow through doing hard things), providing learning opportunities and support, giving growth-oriented feedback (the engine of improvement), and offering mentorship/coaching — the ingredients that help people grow. And supporting growth has a crucial payoff beyond capability: retention.

A crucial link: growth and retention are deeply connected — people stay where they grow and leave where they stagnate:

Growth and retention are deeply linked — people stay where they grow and leave where they stagnate — so investing in people’s development is investing in retention (a virtuous cycle of capability and retention). This link makes growth doubly valuable. Career development is the longer-term dimension.

Career development

Career development — supporting people’s longer-term career advancement (not just current-role growth) — is an important part of developing and retaining people:

Growth and career development — supporting people’s skill growth (challenging work, learning, feedback, mentorship) and longer-term careers (understanding aspirations, providing paths and opportunities) — builds a more capable team and retains people (growth and retention are deeply linked, especially for your best, most ambitious people). It’s a high-return, often-neglected investment. Next: retention and engagement — keeping good people.
