Culture, structure and change, and capstone: diagnosing an organization

The earlier lessons examined individuals and groups. This final lesson steps back to the organization as a whole. Three organizational-level forces shape almost everything covered so far: culture, the shared assumptions and values that tell people how things are really done; structure, the formal arrangement of jobs, authority and coordination; and change, the process by which organizations adapt. The lesson ends with a capstone in which you diagnose an invented company using tools from the whole course.

What organizational culture is

Organizational culture is a system of shared meaning held by members that distinguishes the organization from others. Edgar Schein described culture at three levels. Artifacts are the visible structures and processes: office layout, dress, language, rituals, stories and the way meetings run. Espoused values are the stated strategies, goals and philosophies, such as a values statement on the wall. Basic underlying assumptions are the unconscious, taken-for-granted beliefs that actually guide behaviour, such as "Mistakes are career-ending" or "The customer is always right, even when staff are abused". The deepest level is the most powerful and the hardest to change. When espoused values and basic assumptions conflict, people follow the assumptions.

A strong culture is one in which core values are intensely held and widely shared. Strong cultures increase behavioural consistency, reduce turnover and act as a substitute for formal rules, but they can resist change, make it hard to integrate people who are different and become liabilities after mergers or when the environment shifts. Most large organizations also have subcultures, for example in different departments, locations or professions, and a hospital's surgical culture may differ sharply from its administrative culture. A dominant culture expresses the core values most members share.

The competing values framework, developed by Robert Quinn and colleagues, classifies cultures along two dimensions: internal versus external focus, and flexibility versus stability. This produces four types. A clan culture is internally focused and flexible, emphasizing collaboration, mentoring and loyalty. An adhocracy culture is externally focused and flexible, emphasizing innovation, risk-taking and agility. A market culture is externally focused and stable, emphasizing competition, results and customer focus. A hierarchy culture is internally focused and stable, emphasizing control, efficiency and procedures. Most organizations blend all four, and the framework is useful for diagnosing gaps between the current and preferred culture.

How culture is created and sustained

Culture often begins with founders, who hire and keep people who share their views, socialize them into their ways of thinking and model behaviour that others copy. Once established, three forces sustain it. Selection favours candidates who fit, sometimes at the expense of diversity (lesson 2). Top management signals what really matters through what it pays attention to, measures, rewards and tolerates. Socialization, the process that adapts new employees to the culture, moves through a pre-arrival stage (expectations formed during recruitment), an encounter stage (when expectations meet reality) and a metamorphosis stage (when the new member adjusts). Structured onboarding programs, assigned mentors and early realistic job previews improve retention and speed up productivity.

Employees learn culture through stories (about the founder who slept in the factory, or the manager fired for covering up an error), rituals (award ceremonies, all-hands meetings), material symbols (office size, who gets a parking spot) and language (acronyms and jargon that mark insiders). Leaders who want to know the real culture should listen to the stories people tell new hires, not just read the values statement.

Culture shapes ethical behaviour, inclusion and safety. An ethical culture combines clear standards, visible ethical role models, protection for people who raise concerns and consequences for misconduct. Harassment and other abuses of power (lesson 9) are much more likely in cultures that tolerate disrespect, protect high performers whatever their behaviour and discourage reporting. A positive culture builds on strengths, rewards more than it punishes and emphasizes growth. A culture of psychological safety, discussed in lesson 7 and in depth in HSE-109, is closely linked to learning and error reporting.

Organizational structure

An organizational structure defines how tasks are formally divided, grouped and coordinated. Six elements describe any structure. Work specialization is the degree to which tasks are divided into separate jobs. Departmentalization is the basis on which jobs are grouped: by function, product or service, geography, process or customer. The chain of command is the unbroken line of authority from the top to the lowest level that clarifies who reports to whom. Span of control is the number of employees a manager can efficiently direct. Centralization is the degree to which decision-making is concentrated at a single point. Formalization is the degree to which jobs are standardized and governed by rules and procedures.

Structures range from mechanistic to organic. A mechanistic structure has high specialization, rigid departments, a clear chain of command, narrow spans, centralization and high formalization; it suits stable environments and routine technology. An organic structure has cross-functional teams, free flow of information, wide spans, decentralization and low formalization; it suits uncertain environments and non-routine work. Strategy, size, technology and environment all influence which structure fits. Innovation strategies favour organic structures, cost-minimization strategies favour mechanistic ones, and large organizations tend to become more specialized and formalized.

Common structural designs include the simple structure (low departmentalization, wide spans, centralized authority in one person, typical of small firms), the functional structure (grouping by functions such as marketing, finance and operations), the divisional structure (self-contained units for products, regions or customers), the matrix structure (dual reporting to functional and project or product managers, which improves coordination on complex projects but creates role conflict), team structures, and network or virtual structures that outsource many functions and coordinate through contracts and technology.

Hybrid and remote work as structure and culture

Hybrid and remote work have become one of the biggest organizational design questions of the decade. Arrangements range from fully on-site, through hybrid models with set or flexible office days, to fully remote. Research suggests hybrid work can maintain productivity and reduce turnover, while fully remote work brings flexibility and access to wider talent pools but makes mentoring, informal learning, innovation through chance encounters and cultural transmission harder. Proximity bias, favouring people who are seen more often in the office, can affect promotions and LMX relationships (lesson 10). Many large employers announced stricter return-to-office requirements in 2024 and 2025, while others kept flexible models as a recruiting advantage.

Whatever model an organization chooses, success depends on deliberate design: clarity about which work is best done together and which alone, norms for communication and availability, fair evaluation based on outcomes, investment in in-person time with a purpose, and attention to the experience of remote members. Rules on electronic monitoring and the right to disconnect (lesson 6) also shape how hybrid work feels to employees.

Organizational change

Organizations change in response to forces such as technology, economic shocks, competition, social trends, demographics, regulation and politics. Change can be planned or unplanned, incremental or transformational. Planned change aims to improve the organization's ability to adapt and to change employee behaviour. The difficulty is that people often resist it.

Resistance to change has individual sources: habit, concern about security, economic factors such as fear of lost income, fear of the unknown and selective information processing that filters out arguments for change. It also has organizational sources: structural inertia, limited focus of change (changing one part of a system without the others), group inertia, threats to expertise, threats to established power relationships and threats to resource allocations. Resistance is not always bad. It can signal real problems with a change plan, and treating resisters as obstacles rather than sources of information is a common mistake.

Kurt Lewin's three-step model describes successful change as unfreezing the status quo, moving to a desired end state and refreezing the new change to make it permanent. Unfreezing involves increasing driving forces for change, decreasing restraining forces or both, a process Lewin called force-field analysis. Refreezing involves reinforcing new behaviours through structures, rewards and norms so people do not drift back. Critics argue that in today's environment, organizations rarely have time to refreeze, but the idea of reinforcing change remains essential.

John Kotter's eight-step plan, based on studying change efforts that failed, expands Lewin's model: (1) establish a sense of urgency; (2) form a coalition with enough power to lead the change; (3) create a new vision and strategies; (4) communicate the vision throughout the organization; (5) empower others to act by removing barriers and encouraging risk-taking; (6) plan for, create and reward short-term wins; (7) consolidate improvements and produce more change; (8) anchor the changes in the culture. Steps 1 to 4 correspond to unfreezing, 5 to 7 to moving and 8 to refreezing.

Other approaches to change include action research, a cycle of diagnosing, analysing, feedback, action and evaluation that involves members throughout; organizational development interventions such as team building, process consultation and appreciative inquiry, which focuses on what an organization does well and builds on it; and continuous improvement methods that make change routine. Research on change consistently finds that participation, fair implementation, credible leadership and attention to employees' well-being improve the odds of success. It also finds that many people experience change fatigue when initiatives pile up without visible results, so organizations should limit the number of simultaneous changes and finish what they start.

Capstone: diagnosing an organization

The capstone asks you to diagnose Northfield Outfitters, an invented retailer of outdoor clothing and equipment. The case is fictional and simplified, but it is built to exercise the tools from all twelve lessons. Read the facts, then work through the diagnostic steps below.

Northfield Outfitters has 420 employees: 300 in 18 stores across Ontario and British Columbia, 70 in a distribution centre in Mississauga and 50 at a head office in Toronto. The founder, a well-known mountaineer, retired two years ago, and a new chief executive from a large discount chain has introduced store sales targets with monthly bonuses tied to individual units sold. Since then, annual turnover in stores has risen from 22 % to 38 %; an engagement survey (68 % response) shows an eNPS of −18, with the lowest scores on "My manager cares about me" and "I am recognized for good work"; customer complaints mention pushy staff; and the distribution centre and stores blame each other for stock errors. Head office staff work hybrid; store staff report that decisions arrive by email with no explanation. A posting for store managers listed a pay range of $55,000 to $110,000.

To compute a final score, multiply each criterion score by its weight and add. A diagnosis scoring 8 on evidence, 9 on theory, 7 on recommendations, 9 on ethics and 8 on clarity earns 0.25 × 8 + 0.30 × 9 + 0.25 × 7 + 0.10 × 9 + 0.10 × 8 = 2.0 + 2.7 + 1.75 + 0.9 + 0.8 = 8.15 out of 10.

For your own capstone, choose either Northfield Outfitters or an organization you know well, using the portfolio notes you kept from each lesson. Keep identifying details out if the organization is real. Aim for a diagnosis of about 1,500 to 2,000 words with a one-page summary of recommendations and measures. Organizational behaviour is ultimately practical: the test of a good diagnosis is whether it would help real people do better work and have better working lives.
