Managers, leadership and decision making

Management and leadership#

FoundationAQA 7132 3.2.1DfE GCE Business - management and leadership

Management and leadership overlap but are not the same. Management is the process of getting things done through the effective organisation of resources; the classic functions of a manager, following Henri Fayol, are to plan, organise, direct (or command and coordinate) and control. A manager sets targets, allocates resources, monitors performance and corrects deviations - the day-to-day machinery of running an organisation. Leadership is the ability to influence and inspire others towards a vision or goal: leaders set direction, motivate, and win the commitment of followers. The often-quoted distinction is that managers do things right (efficiency) while leaders do the right things (direction) - a manager administers, a leader innovates.

In practice a good senior figure needs both sets of skills, but the balance shifts with the situation. A stable, routine operation may need strong management to run efficiently; a business facing change, crisis or a new strategy needs leadership to set a new direction and carry people with it. Someone can be a capable manager but a poor leader, or an inspiring leader who neglects the disciplines of management - and either imbalance harms the business. Recognising which the situation demands is itself a management skill.

The functions of management give a useful framework for analysing what a manager actually does. Planning means setting objectives and deciding how to meet them; organising means arranging the people, finance and physical resources to carry out the plan; directing (or leading) means guiding and motivating staff to perform; and controlling means measuring performance against the plan and taking corrective action. A failure in any one function shows up as a business problem - poor planning leads to drift, poor organising to waste, poor directing to low morale, and poor control to targets missed without anyone noticing in time.

How managers behave depends heavily on their assumptions about people, captured in Douglas McGregor's Theory X and Theory Y. A Theory X manager assumes employees are inherently lazy, dislike work and must be closely supervised, directed and controlled - which tends towards an autocratic style. A Theory Y manager assumes employees are self-motivated, seek responsibility and can exercise self-direction - which tends towards a democratic, empowering style. These assumptions are self-reinforcing: a Theory X manager who tightly controls staff may create exactly the passive, uncommitted workforce they expected, while a Theory Y manager who trusts staff may unlock initiative. The assumptions a manager holds therefore shape the leadership style they adopt, which is the subject of the next section.

Worked example

Diagnosing a leadership-versus-management gap

A charismatic founder has grown a business to 60 staff. Sales are strong, but projects run late, budgets are exceeded and staff are unclear about priorities. Diagnose the underlying problem and recommend an action.

Match symptoms to functions
Strong sales and a clear vision point to effective leadership. Late projects, overspending and unclear priorities are failures of the management functions - planning, organising and controlling.
Interpret
The business is well led but poorly managed: it has direction but lacks the systems to plan, allocate resources and monitor performance as it has scaled.
Recommend
Recommend appointing an operations or general manager to install planning and control systems, freeing the founder to lead. The judgement depends on whether the founder will delegate control - visionary founders often resist it.

Result: The problem is weak management (planning and control), not weak leadership; recommending a strong manager to complement the visionary founder addresses the specific failing symptoms reveal.

Typical mistakes

Treating 'manager' and 'leader' as synonyms - they are related but distinct roles that a person may hold to different degrees.
Describing the functions of management generically without applying them to what the manager in the case actually needs to do.

Leadership styles and the Tannenbaum-Schmidt continuum#

StandardAQA 7132 3.2.1DfE GCE Business - leadership styles

The Tannenbaum-Schmidt leadership continuum

Fig. 1As the manager's use of authority falls (left to right), the area of freedom for subordinates rises. Most managers move along the continuum depending on the decision.

Leadership style describes how a leader exercises authority and involves others in decisions. Four styles form the core of the specification. An autocratic leader makes decisions alone and tells subordinates what to do, keeping tight control; this can be fast and clear, and works well in a crisis or with an inexperienced workforce, but it can demotivate skilled staff and stifle ideas. A paternalistic leader also decides, but does so in what they see as the best interests of staff, consulting and explaining like a benevolent parent; it can build loyalty but remains fundamentally top-down. A democratic leader involves employees in decisions and delegates authority, which can improve motivation, harness good ideas and develop staff, but it is slower and depends on a capable, willing workforce. A laissez-faire leader sets broad goals and then leaves employees largely to their own devices; this can empower creative, expert teams but risks a lack of direction and coordination if it slides into neglect.

No single style is best - the appropriate style depends on the task, the workforce, the time available and the leader's own personality. A useful way to picture the choice is the Tannenbaum and Schmidt continuum, which shows leadership not as four discrete boxes but as a smooth spectrum. At one end the leader uses maximum authority and simply tells; moving along, they sell (persuade), then consult, then join in the decision, and at the far end they delegate, giving subordinates the maximum area of freedom. As the manager's use of authority falls, the subordinates' area of freedom rises. The continuum captures the reality that most managers adjust where they sit depending on the decision.

The choice of where to sit on the continuum is driven by three sets of forces that Tannenbaum and Schmidt identified: forces in the manager (their confidence in the team, their values and their own preferred style), forces in the subordinates (their competence, their readiness for responsibility and their expectations) and forces in the situation (the type of problem, the pressure of time and the culture of the organisation). A capable, experienced team facing a complex creative problem with no immediate deadline invites a delegating style; an inexperienced team facing an urgent crisis invites a telling style. This 'it depends' quality is exactly what makes leadership style a rich source of evaluation.

The consequences of leadership style ripple across the business. Style affects motivation and staff retention (over-controlling styles can drive good people away), the speed and quality of decisions (autocratic is fast but may miss information a democratic approach would surface), the development of employees (democratic and delegating styles build capability), and the organisation's ability to cope with change. The strongest answers link style to the specific workforce and objectives in the case, and recognise that the same leader may - and often should - use different styles for different decisions, rather than labelling a leader as one fixed type.

Worked example

Choosing a leadership style from the situation

A manufacturer must decide how to lead two teams: a production line of new, low-skilled temporary staff working to tight safety rules, and a research team of experienced engineers developing a novel product. Recommend a position on the Tannenbaum-Schmidt continuum for each.

Assess the forces for the production line
Subordinates are inexperienced; the situation demands strict safety compliance and clear instruction; time and error tolerance are low. These forces push towards the authority end - a telling (autocratic) or selling style.
Assess the forces for the research team
Subordinates are highly skilled and self-directed; the task is complex and creative; there is no immediate safety constraint. These forces push towards the freedom end - a joining (democratic) or delegating style.
Recommend
Lead the production line near the 'tells/sells' end for clarity and safety, and the research team near the 'joins/delegates' end to harness expertise and motivation. The same manager uses different styles - the right position depends on the forces in each situation.

Result: The production line suits an autocratic/persuasive style and the research team a democratic/delegating style - demonstrating that the best position on the continuum depends on the workforce, task and situation, not a fixed preference.

Typical mistakes

Claiming democratic leadership is always best - it is slower and relies on a capable, willing workforce, and a crisis may need an autocratic style.
Treating a leader as a single fixed type rather than someone who moves along the continuum for different decisions.

How managers make decisions#

StandardAQA 7132 3.2.2DfE GCE Business - decision making

The scientific decision-making process

Fig. 2The scientific decision-making process is a logical loop: the review stage feeds learning back into future decisions.

Managers make decisions in two broad ways that sit at opposite ends of a spectrum. Scientific (data-driven) decision making follows a logical, evidence-based process: define the problem, gather and analyse data, generate and evaluate options against objectives, choose, implement and then review the outcome. Its strengths are objectivity, the ability to justify a decision to stakeholders, and reduced reliance on one person's judgement. Intuitive decision making relies on the manager's experience, judgement and 'gut feeling'. Its strengths are speed, and the ability to act where data is scarce, unreliable or too slow to gather - which is often the reality of business. Most real decisions blend the two: data informs judgement rather than replacing it.

Every significant decision involves opportunity cost - choosing one option means giving up the benefits of the next best alternative - and this should be built into the evaluation of options, not ignored. A firm that commits £2 million and its best managers to a new product forgoes whatever else that money and talent could have achieved. Good decision making makes the opportunity cost explicit, because the true cost of a choice is not just the cash spent but the best alternative sacrificed.

Decisions are made under conditions of risk and uncertainty, and the two are different. Risk exists where the possible outcomes and their probabilities can be estimated (for example, a 30 per cent chance a product launch fails) - this is the world in which tools like decision trees operate. Uncertainty exists where outcomes cannot be sensibly assigned probabilities at all, often because the situation is genuinely novel (a radical new technology, an unprecedented crisis). Recognising which a manager faces matters: quantitative tools help with risk but can give false confidence under true uncertainty, where scenario planning and judgement are more appropriate.

The value of a structured, scientific process is that it improves the average quality and defensibility of decisions and creates a record that can be reviewed and learned from. Its limitations are real, however: data is often incomplete, out of date or biased; gathering it costs time and money; and an over-reliance on analysis can produce 'paralysis by analysis' that misses a fast-moving opportunity. This is why the specification pairs the scientific process with the recognition that experience and intuition remain essential, and why the best managers know when to analyse and when to trust judgement.

Worked example

Making the opportunity cost of a decision explicit

A manufacturer can use spare capacity either to fulfil a £150,000 contract earning £40,000 contribution, or to trial a new product that might, but is not certain to, open a larger market. Show how opportunity cost frames the decision.

Identify the alternatives
Option A: the £150,000 contract, giving a fairly certain £40,000 contribution. Option B: the new-product trial, with an uncertain but potentially larger long-term payoff.
State the opportunity cost
Choosing A means giving up the possible larger future market (the opportunity cost of A). Choosing B means giving up the near-certain £40,000 contribution (the opportunity cost of B).
Decide with the condition in mind
If the new market's payoff can be given probabilities, this is a risk decision suited to quantitative appraisal; if it is genuinely novel, it is uncertainty, where judgement and the firm's strategy matter more. Making the opportunity cost explicit clarifies exactly what is being traded off.

Result: The choice trades a near-certain £40,000 contribution against an uncertain larger market; naming the opportunity cost of each option - and whether the future can be given probabilities - is what turns a hunch into a reasoned decision.

Typical mistakes

Using 'risk' and 'uncertainty' interchangeably - decision trees quantify risk, not genuine uncertainty.
Assuming more data always improves a decision, ignoring its cost, its delay and the danger of paralysis by analysis.

Decision trees and expected values#

AdvancedAQA 7132 3.2.2DfE GCE Business - decision trees

A decision tree with expected values

Fig. 3Rolling back the tree: each chance node's expected value is the probability-weighted sum of its payoffs. Net gain then deducts the cost of each option - here launch (net £430k) beats extend (net £320k).

A decision tree is a diagram that maps out the options available in a decision, the possible outcomes of each option, the probability of each outcome and its financial payoff, allowing the expected value of each option to be calculated and compared. By convention a square node represents a decision point (a choice the manager controls) and a circular node represents a chance point (an outcome governed by probability). The branches from a chance node are the possible outcomes, each labelled with a probability; the probabilities of the branches from any one chance node must sum to 1, because one of them must happen. The technique turns a tangle of possibilities into a structured, quantified comparison.

The key calculation is the expected value (expected monetary value, EMV) of a chance node, which is the sum of each outcome's payoff multiplied by its probability. Expected value is a probability-weighted average of the payoffs - what the option would earn on average if the same decision were faced many times. To decide between options we then compute the net gain of each: the expected value of its outcomes minus the cost of choosing that option. The rule is to choose the option with the highest net gain. This process of working from the payoffs at the tips back to the decision at the root is called 'rolling back' the tree.

Decision trees have genuine value. They force managers to lay out options, quantify uncertainty and think through consequences before committing; they make the reasoning explicit and defensible; and they are especially useful for comparing options with clear, estimable probabilities and payoffs, such as launch-versus-test decisions. They also make the logic transparent to others, which helps a team agree on a course of action. Used well, a tree disciplines a decision that might otherwise be made on hunch alone.

The limitations, however, are important and are where evaluation marks are won. The probabilities and payoffs are estimates, often little better than educated guesses, and the result is only as good as those inputs ('garbage in, garbage out'); a small change in a probability can flip the recommendation, so the answer can be fragile. Expected value assumes the decision is repeated many times, whereas many business decisions are one-offs where the average is never actually experienced. The technique ignores qualitative factors - the firm's objectives, ethics, staff morale, the strategic fit and the attitude to risk (a risk-averse firm may reject the higher-EMV option because its downside is severe). It also takes no account of the time value of money. A decision tree should therefore inform a decision, not make it: the number is a starting point for judgement, not a substitute for it.

\text{Expected value} = \sum (\text{payoff} \times \text{probability})

Expected value (EMV)

The probability-weighted average of the possible payoffs at a chance node. The probabilities of the branches from one chance node must sum to 1.

\text{Net gain} = \text{Expected value} - \text{Cost of the option}

Net gain

Deduct the cost of choosing an option from the expected value of its outcomes. Choose the option with the highest net gain.

Worked example

Rolling back a decision tree

A business must choose between launching a new product (cost £500,000; 0.7 probability of a £1,200,000 payoff, 0.3 probability of a £300,000 payoff) and extending an existing product (cost £200,000; 0.6 probability of a £700,000 payoff, 0.4 probability of a £250,000 payoff). Calculate the expected value and net gain of each and recommend a course of action.

Expected value of 'launch new'
EV = (0.7 x 1,200,000) + (0.3 x 300,000) = 840,000 + 90,000 = £930,000.
$EV = (0.7 \times 1{,}200{,}000) + (0.3 \times 300{,}000) = 930{,}000$
Expected value of 'extend existing'
EV = (0.6 x 700,000) + (0.4 x 250,000) = 420,000 + 100,000 = £520,000.
Net gains
Launch new: 930,000 - 500,000 = £430,000. Extend existing: 520,000 - 200,000 = £320,000. The launch has the higher net gain.
Recommend and evaluate
On the numbers, recommend launching the new product (£430,000 versus £320,000). But note the launch costs £500,000 and its worst case (£300,000 payoff, a £200,000 loss after cost) is more severe than the extension's; a risk-averse or cash-constrained firm might prefer the safer extension. The probabilities are estimates, so the £110,000 gap could easily reverse.

Result: Launching the new product has the higher net gain (£430,000 versus £320,000) and is the recommended choice on the numbers - but the recommendation should be tempered by the larger downside, the reliability of the probabilities and the firm's attitude to risk.

Typical mistakes

Forgetting to subtract the cost of the option, comparing raw expected values instead of net gains.
Using probabilities at a chance node that do not sum to 1, or treating the EMV as a guaranteed amount rather than a long-run average.

Active revision

A firm can invest £300,000 in Project A (0.6 chance of £600,000, 0.4 chance of £150,000) or £120,000 in Project B (0.5 chance of £350,000, 0.5 chance of £90,000). Calculate the net gain of each and recommend a project, then evaluate your recommendation.

Influences on decision making#

StandardAQA 7132 3.2.2DfE GCE Business - influences on decision making

Decisions are never made in a vacuum; a range of internal and external influences shape and constrain them. The business's mission and objectives set the direction: a firm committed to sustainability will reject a cheaper but polluting supplier that a purely profit-focused firm might accept. Ethics - the moral principles guiding conduct - act as a filter on what options are even considered: a decision that is profitable but exploitative may be ruled out by an ethical business, at a possible cost to short-term profit but a possible gain in reputation and staff loyalty. The interaction of ethics and profit is a rich seam for evaluation, because ethical choices often trade short-term cost against long-term reputation.

Resource constraints are a fundamental influence. A decision may be desirable but unaffordable: limited finance, a shortage of skilled labour, insufficient production capacity or a lack of management time all narrow the feasible options. This is why the functional areas interlink - a marketing plan to double sales is worthless if operations cannot expand capacity and finance cannot fund the working capital. The best decisions are made with a realistic view of what the firm can actually resource, not just what it would like to do.

The external environment exerts powerful influence through the PESTLE factors - political, economic, social, technological, legal and environmental forces - and through competition. A recession, a change in the law, a new technology or a competitor's move can all force a decision or change the best option. Some of these influences can be anticipated and planned for; others arrive as shocks. A firm's ability to scan its environment and respond is itself a source of competitive advantage, and links this chapter forward to the strategic-position analysis later in the course.

Finally, stakeholders influence decisions. The expectations and power of shareholders, employees, customers, suppliers, the community and government all press on a decision, often in conflicting directions. A powerful group can effectively veto or force a choice - shareholders demanding higher dividends, a union threatening industrial action, a regulator setting rules. Weighing these influences is the essence of managerial judgement: a decision that is optimal on a spreadsheet may be unworkable if a key stakeholder resists it. Understanding who must be carried with a decision is as important as the decision's financial logic - which leads directly to the management of stakeholder relationships.

Worked example

Weighing ethics against profit

A coffee chain can raise its gross margin by 4 percentage points by switching from fairly traded to conventional beans. Evaluate the decision using the influences on decision making.

Identify the influences
Objectives and ethics: the chain markets itself as ethical, so the switch conflicts with its mission. Stakeholders: customers who value fair trade may object; shareholders may welcome higher margins. External: growing social concern about sourcing raises reputational risk.
Weigh short versus long term
Short term, the 4-point margin gain lifts profit. Long term, losing the ethical positioning could cut sales, damage the brand and undermine the very differentiation that lets the chain charge a premium.
Reach a judgement
For a business whose brand rests on ethics, the reputational and strategic cost likely outweighs the margin gain, so it should not switch. The judgement depends on how central the ethical claim is to its customers and how visible the change would be.

Result: Because the chain's differentiation and premium pricing rest on its ethical positioning, the reputational and strategic risks of switching outweigh the short-term margin gain - showing how objectives, ethics and stakeholders override a narrow profit calculation.

Typical mistakes

Listing influences generically instead of showing how a named influence changes the specific decision.
Treating ethics and profit as always opposed - ethical decisions can raise long-run profit through reputation and loyalty.

Managing stakeholder relationships#

StandardAQA 7132 3.2.3DfE GCE Business - stakeholder management

Methods of managing stakeholder relationships

Fig. 4Proactive methods - communication, negotiation, partnership and CSR - reduce conflict and build durable relationships, at some cost in time and money.

Because a business affects and is affected by many stakeholder groups whose interests differ, managing stakeholder relationships is an active management task, not an afterthought. The shareholder concept holds that managers' first duty is to the owners who provide capital and bear risk; the stakeholder concept holds that a business should account for the interests of all affected groups. Most firms operate somewhere between the two, and how a firm resolves this shapes its whole culture and reputation. Managing relationships well means anticipating each group's expectations, communicating with them, and resolving conflicts before they escalate.

Stakeholder conflict is inevitable because resources are finite and interests compete: paying employees more, charging customers less, paying suppliers promptly and reducing environmental impact all reduce the funds available for shareholder returns, at least in the short run. A pay rise pleases employees but may worry shareholders; a price cut pleases customers but squeezes margins; a factory expansion creates jobs the community wants but may raise the pollution it fears. Managers cannot satisfy every group fully and must decide whose claims to prioritise on each issue - which is where the power-interest grid from the previous chapter helps them target their effort.

There are recognised methods for managing these relationships. Good communication and consultation - keeping stakeholders informed and genuinely listening - builds trust and reduces the surprises that trigger conflict. Negotiation and compromise can find outcomes acceptable to competing groups, such as a phased pay deal or a mitigation package for a community. Building long-term partnerships with suppliers and involving employees in decisions turn potential adversaries into allies. Corporate social responsibility (CSR) - going beyond legal minimums on social and environmental matters - can align the firm with community and customer expectations. The aim is to move from managing conflict reactively to managing relationships proactively.

Whether a stronger stakeholder orientation pays off is an evaluative judgement. The case for it is that engaged employees, loyal customers, reliable suppliers and a supportive community reduce risk and build durable value; the case against is that it can slow decisions, raise costs and blur accountability, and that ultimately the owners' capital is at stake. The right balance depends on the firm's ethics and ownership, the industry, the bargaining power of each group and the time horizon. A firm judged over decades has more reason to invest in stakeholder relationships than one under intense short-term shareholder pressure - and the tension between these horizons is central to how modern businesses are run.

Worked example

Resolving a stakeholder conflict

An airline plans to add early-morning flights that would raise revenue and create jobs but increase noise for residents near the airport. Recommend how it should manage the conflict.

Map the conflict
Shareholders and employees (high interest) gain revenue and jobs; residents and the local council (high interest, and the council has power) lose amenity and may oppose planning permission.
Select management methods
Consult residents early; negotiate a compromise such as a cap on the number of early flights, quieter aircraft, or a community fund; keep the council informed to protect planning approval.
Evaluate
Proactive consultation and compromise are likely to secure approval and protect the airline's reputation at a modest cost, whereas pressing ahead unilaterally risks refusal and lasting hostility. The best approach depends on the council's power and the strength of local opposition.

Result: The airline should manage the conflict proactively - consulting residents, compromising on flight numbers and aircraft type, and engaging the council - because the reputational and planning risks of ignoring a high-interest, high-power group outweigh the cost of accommodation.

Typical mistakes

Describing stakeholder groups without addressing the conflict between them or how it would be managed.
Assuming corporate social responsibility is costless - it can raise costs and must be weighed against its reputational benefits.
