Production (or Manufacturing) planning is the organization of manufacturing activities so that customer demands and orders are met while utilizing resources such as machines, equipment and labor in line with the organization's performance objectives.
Production planning is a critical business process for the success of manufacturing organizations.
Producers need a production planning process that responds to both customer expectations and their corporate goals.
Many factors affect how production is planned. The presence of numerous elements such as customer orders, current stocks, material requirements, resource capacities and costs makes accurate and efficient production planning challenging.
Production planning aims to balance demand and supply resources with competitive, profit-oriented decisions.
To design production planning processes properly, it's important to clearly define how production planning relates to other planning processes.
Considering the horizons, scopes and impacts of decisions, grouping production planning activities into hierarchical levels is useful.
Production planning decisions can generally be examined at three levels:
These levels determine the scope and depth of production planning. Decisions at each level constrain and direct lower-level decisions.
Addressing production planning decisions at these levels enables more effective and efficient management of production processes.
Each hierarchical level can be further subdivided. For example, we split the operational level into two sublevels in the table below. Note that organizations may have additional levels and decisions specific to their context.

Production planning decisions are generally made through following steps:
These steps enable the systematic and efficient execution of the production planning process.
There are common practices and factors that must be considered in production planning.
For make-to-order production, meeting delivery dates and for make-to-stock production, avoiding stockouts are core objectives that ensure customer satisfaction and service levels.
On the other hand, costs arising from purchasing, production, storage and logistics must be minimized. Therefore, production planning decisions should minimize these costs while meeting demand. Related functional processes must also be configured accordingly.
Planning production better, can and will reduce purchasing, production, inventory and logistics costs.
As with other planning processes, production planning requires organization-specific custom design.
An organization's planning setup depends on its production strategies, product characteristics, physical infrastructure, supply chain relationships, demand dynamics and other factors related to competition.
The stages of production and material planning, tasks and responsibilities, analysis methods and supporting tools will vary between organizations. The conceptual design should address how the process must be structured and operated in each organization.
The fundamental approach in production planning is to organize planning activities by horizons (long, medium, short), by product groups, products, semi-finished items or operations, and by priorities and assumptions.
Therefore, production planning systems typically need to be tailored to the organization.
Supply Chain Management can be defined as the management approach that covers all stages from raw material sourcing through production, storage, distribution and delivery to the customer.
Production planning relates to functions such as sales, production, warehousing, logistics, purchasing and finance within supply chain operations.
Organizations aiming for excellence in supply chain management and production planning need to structure key functional planning processes.
Failure to integrate sales, production, purchasing, warehousing and logistics planning leads to inefficiencies and financial losses in resource usage and demand fulfillment, negatively affecting on-time delivery performance and profitability.
Therefore, production planning should not be treated in isolation; its relationships must be clearly defined within the organization.
Large deviations in demand forecasts, frequent order changes, cancellations, urgent orders, and highly urgent orders adversely affect purchasing, production, warehousing and logistics processes.
Effective coordination between demand planning and production planning is necessary to ensure customer satisfaction and proper use of resources and materials.

Production cannot be considered independently of inventories. Raw materials and components must be procured so as not to disrupt production plans. In make-to-stock environments, inventory should be planned to protect against demand and supply fluctuations.

Critical warehouse factors include receival, storage, order picking and loading/unloading capacities, as well as carrying and storage costs. Logistics planning organizes distribution of stocks to required locations, focusing on timing, modes of transport and routing. Warehouse and logistics constraints directly affect production plans.

Advances in information technologies have increased the adoption of innovative methodologies in production planning.
These approaches use various optimization techniques developed within the field of Operations Research.
Manual trial-and-error planning for complex production planning problems can be time-consuming, and may lead to suboptimal results. Innovative methodologies can generate more effective and reliable plans in much shorter timeframes.
These techniques help create plans that satisfy customers, increase resource efficiency and minimize costs.

Organizations should first identify gaps and needs in their current production planning processes, then design how to improve or re-engineer them.
Optimum Planlama provides hands-on training and consulting services for production planning processes and identifying tools/software based automation needs.
We recommend in-house workshops for multi-site or complex manufacturers.
Our services for production planning and related processes are listed below.
