Development: Building Long-Term Human Capital
How organisations grow capability for roles that do not yet exist — and why this is different from training
Last Verified: 2026-09-16 | Author: Kateule Sydney | Published by Kat-Syd Resources Hub
Development builds capability for future roles, not current ones.
Summary: Development is the process by which an organisation grows the long-term capability of its people, often for roles that do not yet exist. It is distinct from training, which builds competencies for current roles, and from succession planning, which identifies who will fill specific positions. This post examines what development is, why organisations invest in it, how structured development programs work, and what the historical record shows. Each section addresses the five core elements — why, what, when, who, and how — then closes with a blog analysis of pros and cons grounded in paired international and emerging-market cases.
Method: This post is written as case-based analytical writing. It does not claim personal experience. All cases are drawn from public sources and analysed through an original lens. Every section addresses the five core elements — why, what, when, who, and how — then closes with a blog analysis of pros and cons.
Introduction — The Capability Pipeline Problem
In 2023, the American technology company Microsoft disclosed that its internal talent development and mobility programs had placed over 30,000 employees into new roles in the preceding two years. The programs focused on building capability in cloud engineering, AI, and cybersecurity — three areas where the external market was highly competitive and internal development had become a more reliable source of capability than external hiring. The investment was not about current job performance. It was about building the capability the firm would need three to five years later, in roles that in some cases did not yet fully exist.
Development is defined by Raymond Noe in Employee Training and Development as “formal education, job experiences, relationships, and assessments of personality and abilities that help employees prepare for the future.” The definition contains two components that distinguish development from training: the horizon (future rather than present) and the object (the person rather than the task). Development prepares individuals for what they will become. Training prepares them for what they must do now.
This post examines four interlocking components of the development function:
- What development is — and how it differs from training, education, and onboarding
- Career development and succession — the structured planning processes that prepare individuals for future roles
- Developmental methods — mentoring, coaching, and rotational assignments and their effectiveness
- Development return — how the investment in development produces retention, mobility, and firm-level capability
The analysis draws on two academic traditions. The first is the human capital tradition associated with Gary Becker, which treats development as an investment with measurable returns to both the individual and the firm. The second is the career development tradition associated with Edgar Schein and Douglas Hall, which examines how individuals and organisations jointly construct career paths over time. Where the two traditions conflict, the cases in this post favour the human capital reading.
Chapter 1 — What Development Is and How It Differs from Training
Definition. Development is defined by Raymond Noe in Employee Training and Development as “formal education, job experiences, relationships, and assessments of personality and abilities that help employees prepare for the future.” The definition contains three elements that distinguish development from adjacent activities:
- Future orientation — development prepares for roles the employee may occupy later, not the role they occupy now
- Personal focus — development is about the whole person, not only the task they perform
- Long horizon — development unfolds over years, not weeks
Explanation. Development is frequently confused with training and with career progression. The distinctions matter because each produces a different outcome and requires a different investment decision:
- Training — builds specific competencies for a defined current role; short horizon; measured by job performance
- Development — builds capability for future roles, including roles not yet defined; long horizon; measured by career trajectory and firm-level capability
- Career progression — the sequence of roles an individual occupies over time; can occur with or without development
- Succession planning — identification of specific individuals for specific future positions; a subset of development
The interpretive insight is that development cannot be justified by current performance outcomes. Its justification is the future capability of the firm. Organisations that evaluate development investments against current-year metrics will consistently underinvest in development, because the returns appear years after the cost.
The Five Core Elements. Development must address five questions in a fixed order. Together they form the operational logic of the discipline.
- Why it is done that way — because future capability cannot be hired on demand; firms that develop their people build capability that competitors cannot easily replicate
- What is supposed to be done — grow the long-term capability of employees so that the firm has the talent it will need in future roles
- When it is done — continuously throughout an employee’s tenure; intensified on promotion, high-potential identification, or strategic shift
- Who does what — the individual owns their development; the manager supports and coaches; HR designs programs; senior leadership sponsors and provides role models
- How it is supposed to be done — through a combination of formal learning, stretch assignments, relationships, and reflection; not through classroom instruction alone
Case study. The Japanese trading company Mitsubishi Corporation provides a case in point for long-horizon development. Mitsubishi’s traditional career model places new hires on a 30-year trajectory, rotating them through multiple business units, countries, and functions. The company does not expect new hires to contribute specialised capability for the first several years; the investment is in their eventual capacity to lead complex, cross-border operations. Many of Mitsubishi’s senior executives have spent their entire careers at the firm, moving through a dozen or more roles. By contrast, the American technology company Netflix explicitly rejects the long-horizon development model in favour of hiring fully formed capability at each level. Netflix does not develop junior engineers into senior engineers over a decade; it hires experienced engineers and expects them to perform at senior level immediately. The two models produce different workforce profiles, and both are internally coherent strategies for the capability each firm needs.
Blog Analysis — Pros and Cons. The evidence from Mitsubishi and Netflix supports the following assessment.
- Pros: Long-horizon development (Mitsubishi) produces leaders with deep institutional knowledge and cross-functional capability that cannot be purchased externally. The firm builds a leadership pipeline that no competitor can easily replicate.
- Cons: Long-horizon development is slow and expensive, and the investment can be lost if the employee leaves or the market shifts. Netflix’s approach delivers immediate capability but requires continuous external hiring and produces less institutional knowledge. Neither model is universally correct; the failure mode is choosing the wrong model for the firm’s strategy and pace.
Chapter 2 — Career Development and Succession Planning
Definition. Career development is defined by Edgar Schein in Career Dynamics as “the lifelong process of managing learning, work, leisure, and transitions in order to move toward a personally determined and evolving preferred future.” Succession planning is defined by William Rothwell in Effective Succession Planning as “a deliberate and systematic effort by an organisation to ensure leadership continuity in key positions.” The two processes are related but distinct: career development is individual-driven and long-horizon; succession planning is organisation-driven and position-specific.
Explanation. Career development and succession planning operate at different levels of the organisation and produce different outputs:
- Individual career development — the employee’s own planning of their trajectory; supported by the firm but ultimately owned by the individual
- Organisational talent management — the firm’s effort to identify, develop, and retain high-potential employees
- Succession planning — identification of specific successors for specific critical roles, with development plans to prepare them
- Emergency succession — the fallback plan for unexpected departure; often documented but rarely invoked in practice
The interpretive insight is that succession planning fails when it is treated as a documentation exercise rather than a development process. The plan that identifies a successor without preparing them produces a chart, not a capability. Real succession planning requires active development of the identified successors over years.
The Five Core Elements.
- Why it is done that way — because leadership transitions are high-risk events, and firms that have prepared successors move through them with less disruption
- What is supposed to be done — identify high-potential employees, prepare them for critical roles, and ensure continuity in leadership positions
- When it is done — continuously for high-potential talent; formally reviewed annually; urgently on unexpected departure of a critical role holder
- Who does what — the individual drives their own career; the manager supports development; HR designs talent management systems; the board oversees CEO succession
- How it is supposed to be done — through formal assessment, stretch assignments, mentoring, and progressive exposure to higher-level responsibility
Case study. The American conglomerate General Electric operated one of the most studied succession planning systems in corporate history. Under Jack Welch and his successors, GE maintained a formal process for identifying high-potential executives, rotating them through multiple business units, and preparing them for senior leadership. The system produced three consecutive CEOs — Reginald Jones to Jack Welch to Jeff Immelt — through internal promotion. By contrast, the Japanese electronics company Sony provides an illustration of the risk of not developing internal successors. Sony’s leadership succession between 2005 and 2018 involved a sequence of CEOs whose tenures were widely perceived as unstable, and the company’s performance during this period was weak relative to its historical trajectory. The firm’s internal succession pipeline had not produced candidates who were prepared for the specific strategic challenges the company faced.
Blog Analysis — Pros and Cons. The evidence from GE and Sony supports the following assessment.
- Pros: Sustained succession planning (GE) produces internal candidates who understand the firm’s operations, culture, and strategic context. The transition from one CEO to the next is smoother because the successor has been prepared for the role over years.
- Cons: Succession planning can produce internal candidates who are continuity-oriented rather than transformative, and who may not be suited to the strategic challenges the firm faces next (Sony). The failure mode is not succession planning itself but the assumption that the capability that produced past performance will produce future performance. The plan must be paired with an assessment of the capability the next era requires.
Chapter 3 — Mentoring, Coaching, and Rotational Assignments
Definition. Mentoring is defined by Kathy Kram in Mentoring at Work as “a relationship between a younger adult and an older, more experienced adult that helps the younger individual learn to navigate the adult world and the world of work.” Coaching is defined by Michael Cavanagh in Evidence-Based Coaching as “a collaborative, solution-focused, results-oriented, and systematic process in which the coach facilitates the enhancement of performance in the coachee’s personal and professional life.” Rotational assignments are defined by Michael Campion, Lisa Cheraskin, and Michael Stevens in “Career-Related Antecedents and Outcomes of Job Rotation” as “the lateral transfer of employees between jobs within an organisation, designed to develop capability.”
Explanation. The three developmental methods operate through different mechanisms and produce different outcomes:
- Mentoring — knowledge transfer and career guidance; relationship-based; typically informal or semi-structured; strong effects on retention and career satisfaction
- Coaching — performance improvement and self-awareness; skills-based; typically structured with defined goals; strong effects on specific behavioural change
- Rotational assignments — breadth of experience and adaptability; role-based; typically formal and time-bounded; strong effects on breadth of capability and network
The interpretive insight is that the three methods serve different purposes and are not interchangeable. Mentoring is about who you know; coaching is about what you can do; rotations are about what you have experienced. Development programs that use only one of the three produce partial capability.
The Five Core Elements.
- Why it is done that way — because structured relationships and assignments accelerate capability development faster than formal instruction alone
- What is supposed to be done — deploy mentoring, coaching, and rotational assignments in combination, matched to the developmental needs of the individual
- When it is done — continuously throughout the employee’s tenure; intensified at transitions (new role, promotion, high-potential identification)
- Who does what — the individual engages; the mentor or coach guides; HR designs the programs; managers identify candidates and support participation
- How it is supposed to be done — through structured programs with clear objectives, active participation by all parties, and periodic review of outcomes
Case study. The American financial services firm Goldman Sachs operates a well-documented rotational program for new analysts and associates, moving them through multiple desks and functions within their first two to three years. The program is designed to build breadth of understanding of the firm’s operations and to give participants a network of relationships across the organisation. Goldman reports that participants in the rotational program have higher retention rates and faster promotion trajectories than employees hired directly into specialised roles. By contrast, the Indian conglomerate Tata Group operates a mentoring-centered model for its high-potential executives. Tata’s Tata Administrative Services (TAS) program assigns each participant a senior mentor within the group and rotates them through multiple Tata companies. The mentorship relationships are long-term — often spanning a decade — and are considered a key element of the program’s success in producing Tata’s senior leadership.
Blog Analysis — Pros and Cons. The evidence from Goldman Sachs and Tata Group supports the following assessment.
- Pros: Combining rotational assignments with mentoring (Goldman, Tata) produces capability that no single method can produce alone. Rotations build breadth and networks; mentoring builds judgment and career guidance; the combination produces leaders who are both experienced and well-advised.
- Cons: Both methods are expensive and slow. Rotations remove employees from productive roles for extended periods; mentoring requires senior leaders to allocate significant time. The failure mode is treating any one method as sufficient. Firms that offer only rotations produce capable generalists without judgment; firms that offer only mentoring produce well-advised employees without breadth of experience.
Chapter 4 — Development Return: Retention, Mobility, and Firm Capability
Definition. Human capital is defined by Gary Becker in Human Capital as “the knowledge, skills, competencies, and attributes embodied in individuals that facilitate the creation of personal, social, and economic well-being.” The development return is defined by the same source as the measurable benefit the firm receives from its investment in employee development. Three outcomes constitute the return: retention, internal mobility, and firm-level capability.
Explanation. Development investments produce returns through three mechanisms:
- Retention — employees who see a future at the firm are less likely to leave; development is a signal that the firm is investing in them
- Internal mobility — developed employees can fill positions internally, reducing external hiring cost and preserving institutional knowledge
- Firm capability — the sum of developed employees produces organisational capability that individual hires cannot match
The interpretive insight is that development return is difficult to measure at the individual level because the benefit is realised over years and across multiple roles. The correct unit of measurement is the firm, not the employee. An employee who is developed and then leaves produces no return; an employee who is developed and stays for a decade produces returns that accrue across every role they occupy.
The Five Core Elements.
- Why it is done that way — because firm-level capability cannot be purchased on the open market; it must be developed internally over time
- What is supposed to be done — measure development return at the firm level; track retention of developed employees, internal mobility rates, and capability growth
- When it is done — continuously; through annual reviews of retention and mobility data; through periodic assessment of firm-level capability
- Who does what — HR measures and reports the data; senior leadership reviews it and adjusts investment; managers contribute to development and retention outcomes
- How it is supposed to be done — through structured measurement of retention, mobility, and capability; not through anecdotal success stories alone
Case study. The Indian IT services firm Wipro provides a case in point for the retention effect of development investment. Wipro’s Wipro Academy of Software Excellence (WASE) is a work-study program that allows employees to earn a master’s degree while working at the firm. Participants commit to staying at Wipro for a defined period in exchange for tuition support. The program has been associated with significantly higher retention rates for participants than for comparable employees hired through standard channels. By contrast, the American retailer Amazon has faced documented criticism of its development investment relative to its retention patterns. Amazon’s Career Choice program provides tuition support for employees to pursue degrees and certifications, but multiple reports have documented that many participants do not stay with the company after completing the program. The development investment produces capability, but the return accrues to the individual and to the next employer, not to Amazon.
Blog Analysis — Pros and Cons. The evidence from Wipro and Amazon supports the following assessment.
- Pros: When development is structured to produce retention (Wipro), the investment returns to the firm over years through the employee’s continued contribution and increasing capability. The design of the program — degree completion tied to tenure — aligns the individual’s incentive with the firm’s investment.
- Cons: Development investment without retention produces a transfer of capability to the market (Amazon). The failure mode is not the development itself but the absence of a mechanism that connects the development to continued employment. Development programs that do not address why the employee would stay produce capability for the industry, not for the firm.
