Product group management & category management explained in a practical way
Product group management and category management are key success factors in modern retail and procurement. But what exactly is behind these terms and why are they so important for companies? To help you maintain an overview, in this article we explain in a simple and practical way how you can systematically structure product groups, manage them strategically and thus achieve sustainable competitive advantages.
1. product group management: definition, strategy & examples
1.1. What is product group management?
Material group management is a central component of strategic purchasing and is used to systematically structure procurement activities. The aim is to increase internal transparency and significantly improve the basis for negotiations with suppliers by specifically classifying materials and services into product groups.
Although the two terms are often used as synonyms, category management is clearly distinct from category management, which is often located in the consumer goods sector and is more marketing and customer-oriented. While category management tends to pursue sales-related objectives, the focus of category management is on cost, supplier and process-oriented optimization of procurement. Please also read the detailed explanations below.
1.2. Product group management definition
Material group management is the systematic division of goods and services into homogeneous groups based on criteria such as material type, area of application or supplier assignment. This structuring forms the basis for strategic purchasing decisions, as it bundles comparable requirements and reduces complexity in purchasing.
This methodology makes it possible to
- Reduce costs,
- Simplify processes and
- significantly increase transparency across the entire procurement organization.
In this way, companies create a standardized, data-based decision-making basis for their purchasing strategy.
1.3. Product group analysis as the basis for the strategy
A well-founded product group analysis is the first step towards effective product group management. This involves systematically recording and evaluating consumption data, requirement quantities and supplier structures. This is often followed by an ABC analysis, which can be used to prioritize particularly relevant product groups – for example, according to purchasing volume or strategic importance. In addition, clusters are formed in which articles, services or suppliers are grouped together according to product group affiliation in order to identify and make targeted use of synergies.
1.4. Goals and advantages in purchasing
Product group management pursues several strategic objectives that have a direct positive impact on purchasing performance. Through the targeted bundling of requirements within a product group, volume effects can be generated that lead to noticeable cost reductions.
In addition, the supplier base is optimized and thus your supplier management is supported, as the purchasing department can concentrate more on efficient and strategically relevant partners. This not only promotes quality and delivery reliability, but also the ability to innovate through more intensive cooperation. Another advantage lies in the standardization and automation of procurement processes, which is facilitated with the help of professional product group management – especially in combination with modern SRM systems.
2 What is category management in purchasing?
Category management has established itself as a customer- and market-oriented purchasing management system that has its origins in the retail sector. However, it is now also used in numerous other sectors – from mechanical engineering to the pharmaceutical industry. This is because category management offers real added value wherever companies want to manage complex product ranges and take into account both customer needs and operational objectives.
At the same time, it usefully complements product group management in strategic purchasing by introducing a market-oriented perspective on product categories, while product group management operates more from an internal process perspective.
2.1. Differences between category management and product group management
Even if the two terms are often regarded as mere synonyms, there are subtle but relevant differences between product group management and category management. Here is a differentiated view:
2.1.1. Similarities between the two concepts
Both concepts pursue similar goals:
- Improving transparency and efficiency along the value chain
- Bundling of articles into meaningful groups for better control and analysis
- Optimization of product ranges, prices, supplier relationships and processes
2.1.2. Differences in focus & application context
Both forms of supplier development are widely used in practice – often even in combination. While technology-intensive sectors such as the automotive industry primarily rely on active development, companies with standardized products tend to use passive methods. The modular use of both approaches makes it possible to react flexibly to different types of suppliers and market requirements.
| Feature | Product group management | Category Management |
|---|---|---|
| 1. background to the term | Industry/production characterized | Trade/retail characterized |
| 2. target setting | Internal efficiency, e.g. procurement, cost control, supplier development | External market orientation, optimization of customer benefit |
| 3. typical application | Purchasing departments, materials management, production | Sales departments, product range design, retail companiesTransparent presentation of performance |
| 4. data focus | Systematic review of processes and technical, pricing and supplier-specific aspects | Purchasing behavior, sales data, POS analyses |
| 5. control unit | Comparison with competitors and best product group = internal control concept | Category = Customer-benefit-oriented bundling |
| 6. role of the customer | Mostly considered indirectly | Is at the center (customer view!) |
2.1.3. Practical example for clarification
To better illustrate the respective concepts, here are 2 practical examples:
- An industrial company combines screws, nuts and bolts into the “fasteners” product group – for better procurement planning and price negotiations.
- One retailer groups toothbrushes, toothpaste and dental floss together in the “oral hygiene” category – because customers ask for these products together.
2.1.4. Conclusion on the definition of terms
Category management is customer-oriented and usually anchored in retail. Product group management is process-oriented and often found in purchasing/industry. Both methods benefit from each other: category management provides the internal structure, category management the external market orientation. Companies with a hybrid strategy often combine both concepts.
2.2. Category management definition and process
Category management involves bundling related products into so-called categories that are planned, managed and optimized independently. The aim is to create added value for customers and increase profit margins through the targeted management of these categories.
The category management process comprises several coordinated steps:
- Identification and delimitation of categories
- Analysis of customer needs and market developments
- Development of a product range and pricing strategy
- Selecting suitable suppliers and conducting negotiations
- Monitoring through KPIs and forecasts
Management is data-based, in particular through the responsible role of the category manager, who continuously collates and evaluates information from sales, purchasing and the market.
2.3. Definition Category Manager – Role & Tasks
The category manager plays a central role in category management. They are responsible for ensuring that the respective product category is managed in a commercially successful and customer-oriented manner.
Their tasks include observing market and competitive developments, identifying trends and continuously developing the product range strategy. The Category Manager works closely with other departments such as Purchasing, Sales and Marketing to ensure a holistic view of customer needs. The Category Manager thus becomes the strategic interface and coordinator between internal process optimization and external market orientation.
2.4. Category management example from practice
A classic example of category management can be found in the retail sector. There, for example, all products relating to “outdoor garden furniture” are combined into one category. The responsible category manager analyzes sales figures, plans seasonal promotions, selects suitable suppliers and manages implementation using KPI dashboards and forecasting models.
Companies are also actively implementing this principle in technical purchasing: they are grouping consumables such as screws, seals and protective equipment into a separate category, managing them centrally using coordinated processes and digital tools – not only improving security of supply, but also optimizing cost-effectiveness through structured bundling and transparent management.
3. fundamentals of the product group strategy
A product group strategy is much more than a theoretical concept – it is a practice-oriented management tool that helps to make procurement targeted, efficient and sustainable. Because only when strategy, market understanding and internal requirements are aligned can purchasing success be measurably realized.
3.1. Why a product group strategy is important & its development
Without a clear strategy, product group management remains reactive, unstructured and often inefficient. Only through the targeted development of a product group strategy can goals such as cost efficiency, security of supply or quality improvement be systematically pursued. Maverick buying – i.e. uncontrolled purchasing outside of established processes – can also be significantly reduced in this way. The development process is structured as follows:
- Analyze demand: Which goods are needed when, in what quantity and quality?
- Understanding the market: Which suppliers are available, what market prices apply, how high is the risk?
- Define goals: Whether savings, innovation or sustainability – targets set the direction.
- derive measures: For example, framework agreements, sourcing strategies or supplier evaluations.
- Documentation and communication: Strategies must be recorded, regularly updated and at the same time communicated transparently.
3.2. Product group strategy template & tools
Various tools and templates are available to ensure that strategies can be created and implemented efficiently. For example, the Kraljic matrix is suitable for classifying product groups based on supply risk and impact on the company.
Tools at a glance:
- Excel templates: Simple, flexible and quick to use for smaller companies
- SAP MM, Simmeth SC-Manager: Professional software solutions with templates, algorithms and automation functions
- Strategy templates: Facilitate structuring and ensure that no relevant factors are overlooked
4. product group management in purchasing
Product group management only unfolds its full effect when it is consistently integrated into the strategic purchasing process. It is particularly important to implement the results from the analysis and strategy phase operationally and at the same time to ensure the support of internal stakeholders.
4.1. Product group analysis and classification
The first step is to comprehensively analyze the consumption data: Which goods were procured in which period and at what price? Clear classifications can be made on the basis of this data.
| Tool / Method | Purpose |
|---|---|
| 1. ABC analysis | Categorization by value share |
| 2. pareto principle | Focus on the 20% of product groups that account for 80% of costs |
| 3. volume-value matrix | Combination of consumption quantity and monetary volume |
This systematic classification creates a sound basis for further measures.
4.2. Use of digital tools
Digital solutions play a central role in modern product group management. This is because they help to automate processes, carry out classifications and enable effective controlling at the same time.
Examples of tools and applications:
- ERP systems such as SAP: Automated data analysis and product group assignment
- Cloud platforms such as BME: collaboration, benchmarking, reporting
- SaaS solutions such as SC-Manager: support for analysis, planning and reporting through interactive dashboards
Training and webinars should also be offered to ensure that the tools can be used effectively
4.3. Tasks of the product group manager
The product group manager is a key figure in purchasing. Their main task is to develop, implement and continuously optimize a sound strategy for each product group.
Its tasks include, among others:
- Analysis and strategy development per product group
- Collaboration with demand carriers to clarify requirements
- Supplier management: selection, development, evaluation
- Monitoring and reporting of target achievement, savings and risks
5. typical product groups and categories in product group management
Depending on the industry , the product groups sometimes differ considerably. Nevertheless, many companies follow established classification logics to ensure transparency and comparability.
5.1. Classification important for product group analysis and strategy
A tried and tested approach to classifying product groups is to divide them into A, B and C goods, supplemented by D goods
| Category | Description | Focus |
|---|---|---|
| 1. a-goods | Strategic, high value, low number | Intensive support, central control |
| 2. b-goods | Mean value and volume | Regular review |
| 3. c/d goods | High number, low individual value | Standardization, automation |
This categorization helps to deploy resources in a targeted manner and at the same time to manage the workload sensibly.
5.2. Categorization in the purchasing system for product group management
In digital purchasing systems, product groups can be specifically mapped and simultaneously used for control purposes.
Important aspects here are:
- Uniform designation and numbering
- Clear reporting structures for measuring success
- Possibility of automated assignment with the help of machine learning
This ensures that information flows correctly and that decisions can be made on the basis of reliable data.
5.3. Product group management Examples from practice
Practical example 1: A mechanical engineering company defines “hydraulic components” as a strategic product group, analyzes its supplier structure and concludes group-wide framework agreements.
Practical example 2: A group with decentralized units bundles the procurement of office supplies via a central e-procurement system. As a result, savings of over 20% are achieved through uniform categorization and price negotiations.
Practical example 3: An automotive supplier manages its most important product groups via real-time dashboards and measures key figures such as on-time delivery, availability and price trends – this enables risks to be identified at an early stage and measures to be initiated quickly…
6. strategic application in product group management
The full benefits of strategic category management can only be realized when it is transferred from theory to practice. It is therefore crucial to consistently implement the findings from analyses and strategic considerations. Defined strategies, high data quality, a clear governance framework and suitable digital tools play a key role in this. Close cooperation with the specialist departments is just as important, as this is the only way to effectively anchor measures and achieve operational success.
6.1. From product group analysis to implementation
The transition from analysis to implementation requires a structured approach and the involvement of relevant stakeholders. First of all, suitable strategies should be selected on the basis of the product group analysis – data-based, targeted and at the same time realistically implementable. The next step is to define action plans, clarify responsibilities and set specific time frames.
It is particularly important to actively involve all relevant stakeholders: The requisitioners, purchasing management and related functions such as controlling or technology. Training and joint workshops help to create a common understanding and thus ensure the quality of implementation.
Important implementation steps at a glance
- Action plans with clear responsibilities
- Timing, e.g. pilot phases
- Training for employees involved
- Regular performance reviews based on defined KPIs
6.2. Using strategic levers in product group management
In order to achieve the strategic goals efficiently, various levers can be used in a targeted manner. One of the most effective is the conclusion of framework agreements in combination with volume bundling. This not only enables better conditions to be achieved, but also reduces administrative costs.
Another lever is supplier development, for example through regular audits, joint innovation projects or partnership-based dialog formats such as the SC Manager’s task management integrated into supplier management. This creates added value beyond pure price optimization.
The strategy is supplemented by make-or-buy analyses, which help companies to make well-founded production decisions. Especially in times of volatile markets, this method can help to reduce dependencies and expand strategic in-house services in a targeted manner.
Strategic levers:
- Framework agreements and volume bundling for price optimization
- Supplier development: from audits to co-innovation
- Make-or-buy analyses: decision on whether to produce internally or source externally
These levers make it possible to make a real value contribution over and above the pure price effect.
7. apply & optimize product group management
Successful product group management does not end with strategy development – on the contrary: it only unfolds its full effect through consistent application and continuous optimization in day-to-day operations and strategy. It is important to establish processes in a structured manner, involve employees and at the same time use suitable tools effectively. External consulting can also provide valuable impetus, for example in the selection of digital solutions or the development of best practices.
7.1. Apply product group management
The introduction of structured processes forms the basis for effective implementation. It is advisable to use tried and tested templates and guidelines in order to minimize the effort involved and at the same time ensure the quality of the measures.
Another success factor is anchoring the strategies in day-to-day business. Training and accompanying change management measures ensure that everyone involved develops a common understanding and actively supports the new processes.
It also helps to use concrete practical examples from your own company or comparable sectors to promote acceptance and motivation. Especially when employees immediately recognize the benefits, the speed of implementation and effectiveness increase noticeably.
Elements of a successful application:
- Introduction of clearly defined processes
- Establishment of regular review meetings
- Integration into day-to-day business (e.g. through reporting)
- Promotion of internal acceptance through training
7.2. Optimization in product group management
Product group management is not a one-off project, but a continuous improvement process. It is therefore important to regularly review strategies and make targeted adjustments where necessary – for example using defined KPIs such as savings potential, process costs or delivery reliability.
It is also worth using digital tools systematically to automate and increase efficiency. Workflow-based tools, dashboards and automatic classification functions make a significant contribution to increasing transparency and controllability.
The purchasing team should regularly approach specialist departments in a targeted manner, obtain their feedback and derive specific optimizations from this. This is the only way to ensure that the strategic guidelines also work in practice and can be continuously developed further.
- KPI-based strategy adjustment:
The aim is to continuously align strategic measures with measurable performance indicators such as savings, delivery reliability or throughput times. - Use of digital tools such as the SC Manager:
The aim is to reduce manual effort, increase transparency and efficiently manage all product group activities via dashboards and automated workflows. - Integration of feedback from specialist departments:
The aim is to ensure the practicability and acceptance of the strategies and to incorporate valuable suggestions for improvement from day-to-day operations. - Benchmarks and external audits:
The aim is to objectively assess your own performance, identify potential for improvement and gain new impetus for further development through external perspectives.
This ensures that product group management keeps pace with the company’s objectives and actively contributes to value creation.
8 Conclusion and summary
Product group management and category management are two complementary methods that bring both efficiency and market orientation to purchasing. While product group management focuses primarily on internal processes, cost optimization and strategic control, category management is more closely aligned with the needs of the market and customers.
The systematic classification of goods, sound analyses and strategic management form the basis for sustainable purchasing success. Supported by digital tools, clear role allocations and continuous optimization, companies can strengthen their supplier relationships and overall supplier management as well as leverage economic potential.
It is particularly important that strategies are not only developed, but also actively implemented – through structured processes, regular reviews and close cooperation with all relevant departments.
If you want to use category management successfully, you should pay attention to data quality, a solid governance model and the right choice of tools. At the same time, best practices, training and external consulting help to turn strategic concepts into concrete competitive advantages. In summary, it can be said that well-thought-out and well-implemented product group and category management is not an end in itself – but a key success factor for modern, efficient and future-proof purchasing.
