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:
- People want to grow. Most people want to grow — to get better at what they do, learn, take on more, and advance their careers. Growth is a core motivation (intrinsic — the EQ series: mastery and progress motivate). People are drawn to environments where they’ll grow and frustrated where they stagnate. People deeply want to grow. Growth is a core human motivation.
- Growth builds a more capable team. When people grow (develop skills, take on more), the team becomes more capable over time — growing people multiplies the organization’s capability (from the first post). Investing in growth compounds into a stronger team. Growth builds team capability. Developing people strengthens the org.
- It’s high-value for both. Growth is a win-win — it fulfills people (their desire to grow) and strengthens the organization (more capable team, and retention — below). Supporting growth serves both the individual and the org. Growth benefits people and organization. A genuine win-win.
- Yet it’s often neglected. Despite mattering, development is often neglected (not prioritized amid urgent work, or seen as “nice to have”) — a mistake, since it’s high-value (capability and retention). The neglect makes supporting growth high-leverage (valuable and under-done). Growth is neglected despite its value. An underused high-leverage lever.
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:
- Give challenging, stretching work. People grow most from challenging work that stretches them (slightly beyond current ability) — so assigning growth-oriented work (stretch tasks, new responsibilities, harder problems) develops them. Growth happens through doing challenging things (with support). Give stretching work. Grow through challenge.
- Provide learning and support. Support growth with learning opportunities (time to learn, resources, training) and support (mentorship, guidance, help when stretched). People grow when they can learn and are supported through challenges (not thrown in unsupported). Enable learning and support growth. Resources and help to grow.
- Give growth-oriented feedback. Feedback (the previous post) drives growth — telling people what to improve and how, in a growth-oriented way. Regular, growth-framed feedback is a key engine of development (people improve from knowing what to work on). Feedback fuels growth. Growth needs feedback.
- Mentorship and coaching. Mentorship/coaching (guidance from more experienced people) is powerful for development — helping people learn, navigate, and grow through others’ experience and support. Providing mentorship (formal or informal) accelerates growth. Mentorship accelerates growth. Learn from the experienced.
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.
The growth-retention link
A crucial link: growth and retention are deeply connected — people stay where they grow and leave where they stagnate:
- People stay where they grow. People tend to stay at organizations where they’re growing (learning, advancing, developing) — because growth fulfills a core desire and makes the work rewarding. Growth is a major reason people stay. Growth retains people. Growth keeps them.
- Stagnation drives people away. Conversely, people leave when they stagnate (stop growing, no development, no advancement) — even if other things are fine, lack of growth is a common reason good people leave (to grow elsewhere). Stagnation is a major cause of attrition. Stagnation drives people out. No growth, they go.
- Investing in growth is investing in retention. Because growth drives retention, investing in people’s development is investing in keeping them — a strong link between the two. Organizations that develop people retain them better (and vice versa). Growth investment is retention investment. Develop to retain.
- It’s a virtuous cycle. Growth → more capable and more retained people → a stronger, more stable team → which supports more growth. Investing in growth creates a virtuous cycle (capability and retention reinforcing). Growth creates a virtuous cycle. Capability and retention reinforce.
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:
- Support their career, not just the current role. Career development supports people’s longer-term careers — their advancement, aspirations, and trajectory (not just performance in the current role). Caring about people’s careers (where they want to go, helping them get there) is part of developing them well. Support careers, not just current work. Care about their trajectory.
- Understand their aspirations. Good career development starts with understanding what people want — their career goals and aspirations — so you can help them toward them (aligning growth opportunities with their direction). Understanding aspirations enables meaningful career support. Understand where they want to go. Know their goals.
- Provide paths and opportunities. Career development means providing paths (how people can advance/grow — clear progression) and opportunities (chances to take on more, advance, move toward their goals). People need to see a future and have opportunities to grow into. Provide advancement paths and opportunities. A visible future.
- It’s key to retaining ambitious people. Ambitious, talented people especially care about career growth — they’ll stay where they see a future and opportunity, and leave where they don’t. Supporting careers is key to retaining your best (most ambitious) people (who have the most options). Career development retains your best people. Ambitious people need a future.
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.
Key takeaways
- Growth (people improving their skills and advancing) matters deeply — people want it (a core intrinsic motivation: mastery and progress), it builds a more capable team over time (compounding the org’s capability), and it’s a win-win for people and organization — yet it’s often neglected, making supporting it high-leverage.
- Support development by giving challenging/stretching work (people grow from doing hard things with support), providing learning opportunities and support, giving growth-oriented feedback (the engine of improvement), and offering mentorship/coaching (learning from the experienced accelerates growth).
- Growth and retention are deeply linked: people stay where they grow (growth fulfills a core desire and makes work rewarding) and leave where they stagnate (lack of growth is a common reason good people leave) — so investing in development is investing in retention (a virtuous cycle of capability and retention reinforcing).
- Career development supports people’s longer-term careers (not just current-role growth) — understanding their aspirations (where they want to go), providing clear advancement paths and opportunities, and helping them toward their goals (a visible future).
- Career development is especially key to retaining your best, most ambitious people (who have the most options and care most about career growth — they stay where they see a future and opportunity, and leave where they don’t) — making growth and career development a high-return, often-neglected investment in both capability and retention.
