How to approach this question:
- Definition of Inventory Management System - a system, usually a piece of digital software, that helps an organisation manage their inventory. It oversees the process of ordering stock, receiving it, storing it and converting it into finished goods. Used predominantly in manufacturing organisations. MRP and ERP are types of IMS.
- MRP - Material Requirements Planning- this is a planning, scheduling, and inventory control system used to manage manufacturing processes. Most MRP systems are software-based. The aim is to automate and improve the efficiency of ordering and processing raw materials.
- ERP - Enterprise Resource Planning - this system uses MRP but also includes other operations such as finance, so allows for budgeting and forecasting, and customer relations. ERP gives an organisation a more holistic overview compared to MRP which just focuses on manufacturing.
- When they are used - predominantly in the manufacturing industry for the ordering of goods. Not used for services. Used when there is a lot of maths involved in figuring out how much of something to order and when e.g. a chocolate manufacturer who needs to produce 50,000 chocolate bars a day. MRP / ERP helps the organisation know what to order, how much and when. It helps achieve the 5 Rights of Procurement.
- Advantages - the advantages of MRP and ERP are very similar and in most cases the same: more accurate than manual processes, quicker response times, automated process frees up people to complete more added value tasks, flexibility, has real time information to inform on decision making, improved responsiveness to customers, improved supply chain management, reduction in costs.
- Disadvantages - expensive, complicated, can break down or be hacked (as they're digital systems), only as good as the information put into them. training required to use.
Example Essay:
IMS
An Inventory Management System (IMS) is a software application or set of tools designed to oversee and optimize the management of a company's inventory. The primary goal of an inventory management system is to maintain an accurate record of stock levels, streamline the procurement process, and ensure efficient order fulfilment. This system plays a crucial role in supporting businesses by helping them avoid stockouts, reduce excess inventory, and enhance overall supply chain efficiency.
Inventory Management Systems have the following functions: demand management (which assists with forecasting, and helps the avoidance of overstocking), helps to control stock levels (by stating minimum and maximum levels), replenishment of stock in line with policies, allows automatic reordering when stock levels get low, tracks stock movements (e.g. around a warehouse), allows communication with suppliers and end users, and helps increase safety by ensuring stock isn't damaged or deteriorating.
MRP
MRP stands for Material Requirements Planning, and it is a computer-based inventory management and production planning system used by businesses to optimize the management of materials, components, and finished products in the manufacturing process. MRP is a key component of Enterprise Resource Planning (ERP) systems, focusing specifically on the planning and control of materials and production resources.
MRP systems uses 3 main modules: 1. Master Production Schedule- information on customer orders, forecast orders, customer requirements and stock orders 2. Bill of Materials - the recipe / breakdown of components of the finished product and 3. Inventory Status File - tells you the current stock levels.
How MRP works- For example, a customer wants to order a new sofa. 1. input the customer order into MRP 2.
Check finished stock and if there's a sofa, give the customer that sofa. If there isn't a sofa in stock, the MRP system will look at the Bill of Materials- looking at individual materials needed to make the sofa and will order these, factoring in lead times 3. confirm to customer what the lead time is on getting their new sofa, based on delivery time of materials and time to make it.
MRP is a simple system - it doesn't take into account other business processes and can go wrong due to inaccurate or outdated information.
Advantages of the MRP process include the assurance that materials and components will be available when needed, minimised inventory levels, reduced customer lead times, optimised inventory management, and improved overall customer satisfaction.
Disadvantages to the MRP process include a heavy reliance on input data accuracy (garbage in, garbage out), the high cost to implement, and a lack of flexibility when it comes to the production schedule.
ERP
This is business management software which is used to collect, store, manage, and interpret data from many business activities. It uses MRP but also includes other operations such as finance, HR and customer services.
Therefore it's more powerful than MRP. Where MRP can tell you how much of something to order and what the lead times are, ERP can also consider how many staff are available each day (by looking at holidays and sickness) and factor this into the manufacturing process. It can also produce accurate financial data, manage customer and supplier relationships.
ERP facilitates information flow between all business functions and manages connections to outside stakeholders. SAP and Oracle are examples of ERP systems. There is also ERP II - this extends the system to include links with suppliers and supply chain stakeholders One of the primary advantages of implementing an ERP system is the integration of information across various departments. By providing a unified view of an organization's operations, an ERP system ensures that different functions work with synchronized and consistent data, fostering improved decision-making and collaboration.
Operational efficiency is another significant benefit of ERP systems. Through the automation of routine tasks and streamlined processes, organizations can achieve greater efficiency, reduce manual errors, and enhance overall productivity.
However, one of the primary disadvantages is the high initial implementation costs. Organizations must invest in software licenses, training programs, and customization to align the ERP system with their specific needs.
The complexity of ERP systems and potential customization challenges can pose difficulties, requiring expertise and resources for successful implementation.
Resistance to change among employees is a common hurdle when introducing ERP systems. Employees may be hesitant to adopt new processes and technologies, leading to a slower transition period and potential inefficiencies during the learning curve. Organizations also become dependent on ERP vendors for updates, support, and maintenance, and switching vendors can be disruptive and costly.
In conclusion, while MRP and ERP systems offer numerous advantages in terms of operational efficiency, data integration, and strategic planning, organizations must carefully weigh these benefits against the associated challenges. A well-planned and effectively implemented system can contribute significantly to an organization's success, but the decision to adopt such a system should be approached with a thorough understanding of both its advantages and potential drawbacks.
Tutor Notes
- This is a really hard topic if you don't have a manufacturing background. The way I think about it is this- imagine you're Cadbury's and you're coming up to Easter. How much sugar do you need to buy and when do you need to buy it in order to make all your Easter Eggs? Hard question right? Well MRP / ERP is the clever software that figures that all out for you. It will tell you how much sugar needs to be bought on what day, in order for the delivery time to be right for manufacturing. It will consider storage costs and how quickly Easter Eggs get made in the factory. It's honestly so clever. Feel free to use that example in your essay. Examples like that show the examiner you understand the topic.
- Although they're fabulous systems, using MRP and ERP systems doesn't guarantee success- at the end of the day they're just software- the key to success is in the accuracy of the data that's inputted into the systems and how the systems are used. That would make a strong conclusion.
- This is a good simple video that explains the topic: What is Materials Requirement Planning (MRP)?
(youtube.com) I also like watching How Its Made - a documentary series about factory life. You can find it on BBC Iplayer. If you don't have a manufacturing background it helps give context to some of these dry subjects like MRP and Just-in-Time manufacturing.

How to approach this question
- Sometimes CIPS give you a steer on how to answer the question. My advice is to follow it. The question says you MAY make reference to the following, but I'd use those hints as a guide for content- a paragraph on each and you're done!
- When you've got a 'may make reference to' hint - this means you can completely ignore it and do your own thing and bring in your own ideas. May means it's optional, so you wouldn't be penalised for this. However, you have to consider the examiner's mark scheme- it will detail options of stuff you can write for funding, ownership etc. Then there will be a line at the bottom saying something like 'accept other options such as x and y'. This leaves it up to the examiner to decide whether what you've said is relevant. I'd personally not leave it up to chance you get a lenient examiner. If you write what's definitely going to be on their mark scheme, you're more likely to get more points.
Example Essay
The modern economy is a complex tapestry of various sectors, each with its own distinct characteristics and functions. The three prominent sectors are the public sector, the private sector, and the third sector. These sectors differ significantly in terms of their funding mechanisms, ownership structures, objectives, the concept of shares, and their administration.
Firstly, the public sector is predominantly funded by the government through taxation, grants, and other forms of public revenue. Its very existence hinges on the provision of essential services and the fulfilment of societal needs. These organizations are owned by the government, be it at the federal, state, or local level. Unlike the private sector, the concept of shares doesn't apply in the public sector. Instead, the government allocates budgets to various departments and agencies for public services and projects. The primary objectives of the public sector revolve around the welfare of the citizens, including the provision ofeducation, healthcare, defence, and infrastructure. It is characterized by bureaucratic administration, with decision-making processes subject to governmental regulations and oversight. A prime example is public schools and healthcare systems, which are funded and operated by the government with the primary objective of ensuring universal access to education and healthcare services.
In contrast, the private sector operates on a starkly different paradigm. It is primarily funded by private capital, investment, and profit-seeking activities. Private individuals and corporations own these entities, with ownership shares often represented by stocks. Shareholders invest capital in exchange for ownership stakes and the potential for dividends. The central objective in the private sector is profit maximization, driven by competition in the market. Companies in the private sector are administered by management teams and boards of directors, with decisions guided by market forces. Apple and ExxonMobil are examples of private sector entities, privately owned and publicly traded, with profit motives at their core. Shareholders invest in these companies with the expectation of financial returns.
Lastly, the third sector, often referred to as the nonprofit or voluntary sector, represents a unique economic sphere. It relies on a combination of funding sources, including donations, grants, and earned income, but not taxation. Third sector organizations are not owned by individuals or shareholders; instead, they are governed by boards of directors or trustees. Unlike the private sectors, shares are not applicable in the third sector. These organizations do not seek to distribute profits to owners. The primary objective of the third sector is to serve a social or community purpose, such as addressing societal issues, promoting social change, and providing services that benefit the public. Administration in this sector is overseen by non-profit boards, and it heavily relies on volunteers, philanthropy, and community engagement. For example, the Red Cross operates with the objective of providing humanitarian aid and disaster relief, relying on donations and volunteers to fulfil its mission. Any profits that are made are reinvested into the organisation to further its mission.
In conclusion, the public, private, and third sectors represent diverse economic domains, each with its own funding mechanisms, ownership structures, objectives, and administrative models. These sectors play essential and complementary roles in society, contributing to economic development, public welfare, and social progress. Together, they form the foundation of a balanced and dynamic economic landscape.
Tutor Notes
- I've structured this essay with a paragraph on each sector, but you could have done a paragraph on each theme, thus having 5 paragraphs instead of 3. Either approach works.
- You've got 5 things and 3 sectors, that equals 15 marks. If you give an example of each and a strong intro and conclusion, that's full marks.
- See LO 4.1 p. 203 - there's a cute table with this information on.
