Balancing Demand and Supply with Effective Sales and Operations Planning
One of the most common problems facing manufacturers across all industries is the difficulty of effectively balancing demand with supply. Manufacturers are continually faced with the challenge of determining what to make, how much to make, and when to make it. When companies fail to meet this challenge effectively, they suffer a multitude of consequences.
Failing to balance demand with supply not only affects the entire manufacturing organization, but the complete eBusiness trading network as well. The plant may not have the right raw materials to meet production needs. There may be increased production costs due to unscheduled changeovers to meet unplanned promotional activities. Excessive and costly inventory may be stocked for discontinued or slow-moving items. Conversely, inventory shortages for new and promoted products may inhibit promotional programs. Stockouts may occur because companies failed to have the right product in the right place at the right time. And if there are frequent stockouts, it can lead to increased costs due to expedited orders or, even worse, permanent customer loss. Keeping demand and supply in balance is a constant struggle. The consequences of poor customer service, high inventories, cash flow difficulties, and failure to meet planned business goals lead companies in search of a process to better manage the delicate balance of demand and supply.
The Solution:
Sales and Operations Planning
Sales and operations planning (S&OP) is a
business process that helps companies better
manage demand against supply. The APICS
Dictionary defines the S&OP process as "the
function of setting the overall level of manufacturing
output and other activities to best satisfy
the current planned levels of sales, while meeting
general business objectives of profitability,
productivity, competitive customer lead times,
inventory and/or backlog levels, etc." S&OP
enables management to establish the desired
levels of customer service, inventory levels,
and production plans. More importantly, it
guides the organization toward managing
their business proactively towards optimal
performance.
The S&OP Business Process
The S&OP process is rigorous. Held on a
monthly basis, it includes representatives from
most functional areas, including top management,
sales and marketing, manufacturing,
engineering, and finance. The goal is to reach
consensus on the current status and future
plans for each product family, for both demand
and supply. There are four fundamental steps
in the S&OP process:
- Meeting preparation. Team members are
identified and tasked with gathering information
and calculating performance measures.
Both the demand-forecasting group
and the operations team contribute in this
process. Representatives update the forecast,
aggregate the data into product family
groupings, and identify production constraints
and raw material issues. Data is
gathered and analyzed to identify trends and
compare performance to goals. Exhaustive
reports are then created, and all meeting
materials are distributed to team members
for review prior to the meeting, enabling
them to understand current and expected
performance levels and identify issues.
The importance of preparation and information gathering in the S&OP process often is underestimated. The decisions made in the meeting will only be as effective as the information on which the decisions were based.
- Monthly S&OP meeting. All of the functional
areas that have contributed to the
planning process attend. They first review
actual versus plan for the previous time
period, discussing both sales and operations
results. Sales should focus on understanding
forecasting and customer service issues,
such as why actual sales have been
higher/lower/equal to forecasted sales and
whether customer service objectives have
been achieved. Operations will need to
determine how effectively demand was met:
Did actual output match planned output?
Have inventory/backlog goals been consistently
met? Has obsolete inventory been
reduced?
The group will then review company performance goals to ensure a clear understanding of the corporate business drivers and goals. The team identifies the performance goals and discusses factors that may impact the goals, ultimately creating a business plan to meet these goals. The team then discusses market conditions that may impact achieving the goal, including economic conditions, seasonal considerations (i.e., flu season for a pharmaceutical company or snow season for a ski apparel manufacturer), competitor activity, and general trends in the industry.
The core of the monthly S&OP meeting is the next step in the process. Specific product families are discussed, including exceptions, specific concerns about meeting the specified goals, potential resolutions, and a projected plan. From a sales perspective, demand considerations are reviewed: What will be the future demand for a particular product family? What new products will be required and when will old products be phased out? What will be the demand for the new products? Do we need to stimulate demand to meet sales goals by increasing displays or promotions?
From an operations perspective, supply issues are reviewed: Are we holding excess/obsolete inventory? Do we need to push inventory (i.e., special promotions to deplete inventory, send inventory to discount store for quick reduction)? What changes do we need to make to our production plan including capacity and material considerations? What costs will be incurred? When should the changes be made? Will we incur increased transportation costs by changing production or distribution locations? What resources and time will be required to design, test, and manufacture the new products?
The last activity is to identify and agree on action items. If possible, the group should strive to resolve existing issues with existing data. Team members in attendance should identify and document new issues, assign responsibilities, and set resolution dates.
Longer-term action items involving analysis that will take multiple meetings to complete should be tabled for a later meeting. Finally, the group will want to review future meeting dates and the upcoming months' activities, reiterating the importance of accountability for the action items.
- Modification and communication of
consensus demand and supply plans.
Once the cross-functional team has agreed
on the high-level sales and operations plans,
specific changes to demand and supply
plans follow. The sales team must revise
sales forecasts, marketing/sales plans, and
promotional activities in accordance with
the decisions made in the S&OP meeting.
The operations team must alter production
plans, distribution strategies, and transportation
activities as necessary. The S&OP
documentation is revised to reflect latest
team decisions and is distributed to team.
The meeting minutes are created and distributed. Lastly, the new plans must be communicated to other parts of the organization that are impacted, including procurement, research & development, engineering, etc.
- Executive S&OP session. S&OP teams should identify issues that need executive input, such as long-term strategies, goals, and cross-team issues. The executive team reviews performance and plans, including team performance versus goal and budgets. Discussion of expected sales, production, and inventory, including forecast scenarios (upsides and downsides) occurs. The executive team reviews the decisions, resolves any disputes, and makes clear policy decisions.
The principal benefit of the Sales and Operations Planning process is improved bottom- line performance: having the right product at the right place at the right time. The S&OP process gives executives and managers better control of the business, providing a window into the future, and helping them to leverage intelligence to make better decisions. Improved customer service, reduced inventories, and more efficient production are the primary quantitative benefits. An additional and important result, but one that isn't easily quantified, is that the process encourages and contributes to enhanced teamwork at both the top-management and middle-management levels.
In Sales and Operations Planning, recently published in APICS magazine, Mike Kremzar, vice president, product supply, customer services worldwide, at Proctor & Gamble, notes the benefits of the S&OP process. Krezmar states "The S&OP processes provide the data, the forum, and the measurement tools that lets these leaders continue to make good decisions for their brands, but now with full team understanding, including cost, inventory, and service impacts. The benefits from sales and operations planning have been significant and con tinue to grow. Some of our business units have experienced a 20 percent improvement in inventory with a 25 percent improvement in customer service levels while costs have decreased!"
The S&OP process improves measurements across functional areas. Following a sales and operations planning process enhances a company's flexibility to respond to customer needs and to ship on time and complete more often. Changes in production schedules can be made less radically, operating with less cost and less negative impact on the work force. Inventories and order backlogs can be managed proactively to support the company's delivery and lead-time objectives. Companies using a S&OP process have a more complete view of the business as forecast, production, inventories, and customer lead times are viewed simultaneously for a given product family and a given set of resources. Consequently, companies have been able to simultaneously improve customer service, reduce inventories, shorten customer lead times, and control costs.
Barriers to Success
Sales & Operations Planning must bring
together three critical, interrelated activities:
demand forecasting, sales planning, and operations
planning - which often poses multiple
challenges. To be an effective process, this collaboration
must involve communication and
negotiation between sales, marketing, purchasing,
distribution, manufacturing, and senior
management. The challenge is establishing a
process to enable informed, collaborative decision-
making that results in a balanced demand
and supply plan.
Three common issues make creating an effective S&OP process a challenge. Companies must first overcome unproductive meetings. Many S&OP meetings are largely status updates. Representatives from the business areas use the meeting as a time to discuss general, non-critical information. All information regarding sales and operations that is not in conflict with the current plan should be disseminated and reviewed prior to the meeting.
The S&OP meeting should establish a collaborative environment, creating a forum to discuss and resolve exceptions to the plan. The second common issue is the lack of integrated, flexible planning and measurement tools to support continuous improvement. Often, data is from multiple disparate systems and may be represented in different time buckets and different levels of aggregation. It is not easily and quickly accessed, nor is it easily merged into usable management reports. Participants in the meeting spend an excessive amount of time retrieving the data and developing effective reports to be reviewed in the meeting.
The third common difficulty is a lack of accurate planning information. When a team is setting the overall level of manufacturing output and other activities to best satisfy the current planned levels of sales, it is critical to have particularly accurate forecast and resource capacity projections. Because of limitations in many planning tools, often the forecast and operations plan are unachievable given the available resources.
