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.

, 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.
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.
Time fences
The demand control process requires that all functions agree on time fences within the
planning horizon

best practices. 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, 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.

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

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.
