Four managers – four objectives
“Without the co-ordination provided by S&OP, each function naturally optimises its own area: sales pursues growth, production stability, finance profitability and cash flow, and supply costs.”Section 2.1.2
S&OP – sales and operations planning: a tactical process designed to balance demand and supply over a medium-term horizon. More on slide 11.
How can the objectives of four managers be aligned?
Three levels
Strategic
Direction, competitive positioning, portfolio; decisions hard to reverse (Anthony, 1965; Johnson et al., 2017)
Tactical
The bridge between strategy and day-to-day activity; the critical point of integration
Operational
Execution: its effectiveness directly determines whether the strategic objectives are achieved
What is evaluated at each level
Vertical consistency
Strategic objectives are cascaded consistently into tactical and operational plans.
Operational results, through feedback mechanisms, inform tactical and strategic decisions (Meal et al., 1987).
Without this two-way link the hierarchy remains a formal structure with no real content.
A plan is not a forecast
Forecastdescriptive
An estimate of a likely state: what will most probably happen if nothing changes. It can be right or wrong.
Plannormative
A decision: what the organisation will pursue and what it will do to that end. Not right or wrong but met or not met, ambitious or cautious.
Five stages – one cycle
Cyclical and iterative, not a one-off linear sequence. Three reasons:
- Incomplete information – assumptions are set and tested later.
- The interdependence of plans:
- Change in the environment – plans must be updated continuously.
Assumptions and forecasts
Macroeconomic
growth of gross domestic product, inflation, interest ratesSectoral
competitive dynamics, regulatory changeFirm-level
market share, pricing, efficiency improvementsFinancial
discount rate, tax rates, working capital requirementsPlanning is the modelling of the future, and the future is unknown. The quality of the assumptions – clarity, justification and regular review – is therefore the most important factor in the quality of planning.
Quantitative methods
Time series methods, regression, Monte Carlo simulation, machine learning. Suitable where numerical data about the past are available and it is reasonable to assume that some patterns will continue.usually shorter horizonsQualitative methods
Expert judgement, the Delphi method, scenario planning. Structural breaks – technological, regulatory, demographic – become the principal source of uncertainty.more important over longer horizonsHyndman & Athanasopoulos, 2021, §1.2, §1.4
Modelling and evaluation
Deterministic
One value of the result for each combination of assumptions. Simpler and more widely used, but creates an illusion of spurious precision.Stochastic
Variables are probability distributions, and the result is a distribution. More realistic, but requires more data and expertise.Evaluation is not a procedure “after” planning but an integral part of it – an instrument for modelling decisions.
Comparing alternatives. Which investment creates the most value?
Monitoring assumptions. Is the growth of sales consistent with the assumptions?
Learning. Where were the assumptions wrong? Why?
5 · Decision
Clear decision governance – who decides, on what basis, through what escalation mechanism – is necessary so that the process does not turn into a bureaucratic exercise without real results.
The business plan – an integrated document
Not merely a document of financial projections but a structured system for modelling decisions: it integrates strategic direction, tactical co-ordination, financial forecasts, an implementation plan and risk monitoring. The three layers correspond to the planning hierarchy.
Strategic3–10 years
Mission and vision, market positioning and competitive strategy, business portfolio decisions, major investment programmes, high-level financial objectives – revenue growth, profitability ranges, return on invested capital (ROIC) targets.Tactical1–3 years
Functional strategies: the marketing, operations, personnel and finance plans. Departmental budgets, the project portfolio, the KPI system, an assessment of assumptions and risks.Operationalmonths to a year
Detailed implementation schedules, the allocation of resources, process documentation, the measurement of performance, contingency plans.Chapters 5–8 – functional plans at the tactical level: structure, operating processes, marketing, personnel.
Chapters 9–15 – financial analysis and valuation.
S&OP and IBP
S&OP – a tactical process designed to balance demand and supply over a medium-term horizon.
IBP – a more advanced form of S&OP
Integrated business planning (IBP) adds financial management, strategic priorities and scenario thinking. It is a mechanism for executing strategy – a bridge between the formulation of strategy and everyday activity (Nyman et al., 2025).Organisational alignment
Shared objectives, shared assumptions, clear decision channels, agreed evaluation criteria, disciplined iteration (Markin et al., 2021; Dreyer et al., 2018). It is suggested that the process be assessed by how far it reduces bias in decisions – debiasing (Koller et al., 2020).BSC and OKR
The Balanced Scorecard (BSC) – strategic objectives as KPIs across four perspectives (Kaplan & Norton, 1992, 1996).
The chain learning → processes → customers → finance (Kaplan & Norton, 2001) is a hypothesis: the relationship between the perspectives is logical rather than causal (Nørreklit, 2003, pp. 615–616).
Objectives and Key Results (OKR) – an instrument of tactical and operational execution.
The empirical grounding is still limited – more case studies than controlled studies (Niven & Lamorte, 2016).
BSC – “translating” strategy (long-term), OKR – execution by quarters (short-term). A common root – Drucker’s MBO: how to turn a strategic vision into everyday action.
Five dimensions of a planning system
Five dimensions – an analytical model for assessing the maturity of a planning system. Each is made specific in what follows: operating processes (Ch. 6), marketing (7), personnel (8), financial analysis (9), valuation (13).
