(a) Environment as a major contingency for organisations

Contingency theory holds that there is no one best way to organise; the right structure and management style depend on situational factors, and the external environment is the most important of them. Organisations are open systems that take in resources and information from the environment and depend on it for survival.

The environment has a general part (political, economic, social, technological, legal and ecological forces) and a task part (customers, suppliers, competitors, regulators and unions). The internal environment (culture, resources, people) is shaped by it.

Its demands are described by two dimensions: complexity, the number of elements and their differences, and dynamism, the speed of change. Duncan's classification gives four states, from simple-stable to complex-dynamic, and the more uncertain the environment, the greater the need for information and flexibility.

Planning is needed because the environment cannot be controlled: managers must scan it, forecast and set strategies, buffers and contingency plans. Adaptation follows, since the organisation must change its structure and processes to fit:

• Burns and Stalker found that stable environments suit mechanistic structures and changing ones suit organic structures.
• Lawrence and Lorsch showed that firms in uncertain environments need more differentiation and integration.
• Thompson recommended buffering and boundary spanning.

For example, when e-commerce disrupted retail, traditional retailers had to adopt digital channels, flatter structures and faster decisions. Failure to fit the environment leads to decline.

(b) Important structural dimensions of organisations

Structure is the formal pattern of tasks, authority and communication. Its main dimensions are:

• Complexity: the extent of horizontal differentiation (division of labour, departments), vertical differentiation (number of levels) and spatial dispersion.
• Formalisation: how far rules, procedures and job descriptions are written and enforced.
• Centralisation: how far decision-making is concentrated at the top rather than delegated.
• Specialisation and departmentation: the basis of grouping, by function, product or area.
• Span of control and chain of command: the number of subordinates per manager and the lines of authority.
• Integration and coordination mechanisms, such as committees and liaison roles.

These dimensions interact. A large organisation tends to be more complex and formalised, and a tall structure with narrow spans slows decisions. A good design balances them against the environment, technology and size.

(c) Rules and norms in organisational design

Rules are formal, written, explicit requirements set by the organisation, backed by official sanctions, such as attendance policies or a purchase procedure. Norms are informal, unwritten standards of behaviour that a group develops and enforces through social approval and disapproval, such as dressing styles or how meetings are run. Rules apply to all, whereas norms arise within groups, and a rule can lack acceptance without a supporting norm.

Importance of rules in design:

• They give clarity, predictability and consistency in routine work.
• They achieve coordination and control, substitute for supervision and make for fair treatment.
• They provide legal and regulatory compliance and a basis for accountability.
• They are the main tool of formalisation in mechanistic, bureaucratic structures.

Importance of norms:

• They guide behaviour in situations that rules cannot cover, and are cheaper to enforce.
• They build cohesion, identity and a shared culture, and shape quality and productivity.
• They support or defeat the formal structure: where norms and rules agree, performance rises, and a restrictive norm can defeat a rule.
• They are more important in organic structures, where rules are few.

Designers should therefore use rules to fix essential requirements, and shape norms through leadership, selection, socialisation and rewards so that the two agree.
