Determining requirements: definition & important aspects for buyers
.jpeg)
Needs assessment in a nutshell:
Determining requirements is a systematic process for identifying and quantifying the goods and services required in a defined period of time. It forms the basis for efficient procurement planning and enables Purchasing to optimally manage order quantities, delivery dates and stock levels.
Example: An automotive supplier uses production planning analysis to determine a requirement of 25,000 steel sheets for the coming quarter and plans a staggered procurement of 8,333 units per month in order to optimize storage costs and avoid production bottlenecks.

What is the needs assessment?
Determining requirements is a central process in purchasing and refers to the systematic determination of a company's material and service requirements. It is used to determine the exact scope, quantities and timing of the required goods and services. By carefully determining requirements, a company ensures that all necessary resources are available on time and in the right quantities in order to optimize operational processes.
Core elements of the needs assessment
Significance for purchasing
Determining requirements is essential for purchasing, as it forms the basis for all procurement strategies. A precise determination of requirements makes it possible to avoid excess stock, prevent bottlenecks and optimize procurement costs. It helps to ensure security of supply and increase the efficiency of procurement processes.
Determining demand: from traditional planning to data-driven forecasting
Determining requirements is essential for ensuring efficient materials management and optimizing stock levels. Based on theoretical principles, it plays a central role in procurement logistics and production planning. However, in times of volatile markets and increasing complexity, traditional methods are reaching their limits. This requires a transformation towards modern, data-driven approaches in order to meet the challenges.
Old: Traditional determination of requirements
Traditional approach:
In traditional demand calculation, requirements are usually determined manually on the basis of historical consumption data. Planners use simple tools such as spreadsheets to estimate future requirements. This is characterized by static forecasts without taking current market changes or external influences into account. This approach is prone to inaccuracies, which can lead to overstocking or supply bottlenecks. It also requires a great deal of manual effort and is not very flexible in the face of short-term changes.
New: Data-Driven Forecasting
Data-Driven Forecasting:
The modern approach to determining demand relies on data-driven forecasts using advanced technologies such as AI in purchasing and machine learning. The integration of real-time data from ERP systems, sales statistics and external market information enables more precise and dynamic forecasts. Key innovations include big data analytics, the processing of large volumes of data and the consideration of complex influencing factors. This leads to greater accuracy in forecasting demand, reduces stock levels and significantly increases responsiveness to market changes.
Practical example: Food industry
A leading company in the food industry implemented a data-driven forecasting system that combines sales data, seasonal trends and social media analysis. This modern approach enabled the company to increase its forecasting accuracy by 25%. This led to a 15% reduction in inventory costs and a 30% reduction in stock-outs. The improved demand forecasting also enabled a faster response to market trends and significantly increased customer satisfaction.
Conclusion on the needs assessment
Determining requirements is a fundamental process for the successful purchasing and efficient resource planning of a company. Through precise analyses, modern technologies and systematic methods, companies can optimize their procurement costs while ensuring security of supply. The increasing use of AI and digital tools will further increase the accuracy and efficiency of demand determination and thus represent a decisive competitive advantage.
