Demand management

Demand management is a planning methodology used to forecast, plan for and manage the demand for products and services. This can be at macro-levels as in economics and at micro-levels within individual organizations. For example, at macro-levels, a government may influence interest rates to regulate financial demand. At the micro-level, a cellular service provider may provide free night and weekend use to reduce demand during peak hours.

Demand management has a defined set of processes, capabilities and recommended behaviors for companies that produce goods and services. Consumer electronics and goods companies often lead in the application of demand management practices to their demand chains; demand management outcomes are a reflection of policies and programs to influence demand as well as competition and options available to users and consumers. Effective demand management follows the concept of a "closed loop" where feedback from the results of the demand plans is fed back into the planning process to improve the predictability of outcomes. Many practices reflect elements of systems dynamics. Volatility is being recognized as significant an issue as the focus on variance of demand to plans and forecasts.[1]

In economics

Macroeconomics

In macroeconomics, demand management it is the art or science of controlling aggregate demand to avoid a recession.

Demand management at the macroeconomic level involves the use of discretionary policy and is inspired by Keynesian economics, though today elements of it are part of the economic mainstream. The underlying idea is for the government to use tools like interest rates, taxation, and public expenditure to change key economic decisions like consumption, investment, the balance of trade, and public sector borrowing resulting in an 'evening out' of the business cycle. Demand management was widely adopted in the 1950s to 1970s, and was for a time successful. It caused the stagflation of the 1970s, which is considered to have been precipitated by the supply shock caused by the 1973 oil crisis.

Theoretical criticisms of demand management are that it relies on a long-run Phillips Curve for which there is no evidence, and that it produces dynamic inconsistency and can therefore be non-credible.

Today, most governments relatively limit interventions in demand management to tackling short-term crises, and rely on policies like independent central banks and fiscal policy rules to prevent long-run economic disruption.

Natural resources and environment

In natural resources management and environmental policy more generally, demand management refers to policies to control consumer demand for environmentally sensitive or harmful goods such as water and energy. Within manufacturing firms the term is used to describe the activities of demand forecasting, planning, and order fulfillment. In the environmental context demand management is increasingly taken seriously to reduce the economy's throughput of scarce resources for which market pricing does not reflect true costs. Examples include metering of municipal water, and carbon taxes on gasoline.

Welfare economics

Demand management in economics focuses on the optimal allocation resources to affect social welfare.

Welfare economics uses the perspective and techniques of microeconomics, but they can be aggregated to make macroeconomic conclusions. Because different "optimal" states may exist in an economy in terms of the allocation of resources, welfare economics seeks the state that will create the highest overall level of social welfare.

Some people object to the idea of wealth redistribution because it flies in the face of pure capitalist ideals, but economists suggest that greater states of overall social good might be achieved by redistributing incomes in the economy.[2]

Because welfare economics follows the techniques of microeconomics, where demand planning is part of the process especially the redistribution of the funds through government taxes, fees and royalties to programs for societal good, such as roads, services, income support and agriculture support programs.

Demand management as a business process

Demand management is both a stand-alone process and one that is integrated into sales and operations planning (S&OP) or integrated business planning (IBP).

Demand management in its most effective form has a broad definition well beyond just developing a "forecast" based on history supplemented by "market" or customer intelligence, and often left to the supply chain organization to interpret. Philip Kotler notes two key points: 1. Demand management is the responsibility of the marketing organization (in his definition sales is subset of marketing); 2. The demand "forecast" is the result of planned marketing efforts. Those planned efforts, not only should focus on stimulating demand, more importantly influencing demand so that a business's objectives are achieved.

The components of effective demand management, identified by George Palmatier and Colleen Crum, are: 1. planning demand; 2. communicating demand; 3. influencing demand and 4. prioritizing demand.[3]

Demand control

Demand control is a principle of the overarching demand management process found in most manufacturing businesses. Demand control focuses on alignment of supply and demand when there is a sudden, unexpected shift in the demand plan. The shifts can occur when near-term demand becomes greater than supply, or when actual orders are less than the established demand plan. The result can lead to reactive decisions, which can have a negative impact of workloads, costs, and customer satisfaction.

Demand control creates synchronization across the sales, demand planning, and supply planning functions. Unlike typical monthly demand or supply planning reviews, demand control reviews occur at more frequent intervals (daily or weekly), which allows the organization to respond quickly and proactively to possible demand or supply imbalances.[4]

Time fences

The demand control process requires that all functions agree on time fences within the planning horizon, which should be no less than a rolling 24 months based on integrated business planning best practices.[5] A time fence is a decision point within a manufacturer's planning horizon. Typically, three established time fences exist within a company:

  • Future planning zone - Supply is managed to match demand
  • Trading zone - Demand is managed to match supply for production
  • Firm zone - Demand is managed to match supply for procurement

Demand controller

A demand controller is established when a company implements a demand control process. Unlike a demand planner who focuses on long-term order management,[6] the demand controller is responsible for short-term order management, focusing specifically when demand exceeds supply or demand appears to be less than planned, and engages sales management in both situations. The demand controller works across multiple functions involved in the supply and demand processes, including demand planning, supply planning, sales, and marketing.

Elements

Planning demand involves a full multiple-view process or work flow; including statistical forecast as a baseline from clean "demand history" [not shipments], using the most effective statistical models. Kai Trepte developed the Microsoft Excel add-in "Forecast X" to provide practitioners with a workstation capability to assess the best matches between data and forecast models. Increasingly "predictive forecasts" have moved from a limited use to becoming best practice for more companies. Predictive forecasts use simulation of potential future outcomes and their probabilities rather than history to form the basis for long range (5-10+ years) demand plans. Baseline forecasts are typically developed by demand planners and analysts, who may be regional or centrally located. They work under the guidance of the demand manager. Baseline forecasts are communicated to members of the demand management team. This usually includes regional sales leaders, market managers, and product managers. The team may include customer service leads who manager orders under service agreements with customers and have direct insight into customer demand. For major retailers this is often point of sale data provided to suppliers.[7][8]

Information technology

Information technology and information system demand managers seek to understand in advance how to best meet the needs and expectations of customers, clients, partners, and enablers. Thus, proper forecast and sizing of demand is required in order to deliver a stable and effective technology environment.

Demand management as part of project portfolio management

Romano, Grimaldi, and Colasuonno consider demand management as a harvesting activity, governed by a strategy that gives portfolios direction and a selection model intended to select the best beneficial set of activities aligned with strategic objectives. They suggest component-oriented demand management be approached proactively, with a strategy driven by business objectives, and responsibility of top management representing the chosen strategic direction.[9]
