Managing the supply chain effectively

  • The supply chain is the network of organisations, people, activities and resources that move a product from its basic raw material right through to the final customer

  • It includes:

    • Stock control: planning, implementing and monitoring the movement of raw materials, components, work-in-progress and finished goods

    • Quality control: ensuring output meets standards so that the end product is safe and meets customer expectations

    • Transport networks: ensuring efficient deliveries of good to customers taking account of speed, reliability and costs

    • Supplier networks: developing strong relationships with suppliers willing to work collaboratively to improve quality

  • Global supply chains require these activities to be coordinated across international borders

    • Some stages can be completed at lower cost in other countries

      • E.g. China has a reputation for producing high quality, low-cost electronics components

    • Labour-intensive processing such as clothes manufacturing is outsourced to countries with low labour costs, such as Vietnam

    • Scarce raw materials may only be available in certain countries/regions

Building an effective supply chain

Decision area

What it involves

Make or buy (produce in-house or outsource)

  • Decide whether to produce in-house or buy from specialists

Choosing suppliers

  • Single trusted supplier or multiple back up options

  • Local or global sources

Purchasing approach

  • Bulk buying for discounts, or frequent small orders to stay flexible

Information sharing and use of technology

  • Real-time data, bar-codes, RFID and cloud systems keep production partners fully informed

Logistics structure

  • How many and where warehouses are needed

  • Transport options - use an external haulier or keep control of deliveries

Why an effective supply chain matters

  1. Faster delivery to customers

    • When every link is well-coordinated, products move quickly from factory to shelf, beating slower rivals

  2. Lower operating costs

    • Just-in-time deliveries and bulk purchasing agreements reduce storage, handling and material expenses

    • E.g. Aldi negotiates long-term contracts with a small group of trusted suppliers, helping it minimise warehouse stock and keep prices low

  3. Consistent quality

    • Close, long-term relationships with suppliers make it easier to enforce standards and fix problems early

  4. Greater resilience to shocks

    • A well-planned supply chain includes back-up suppliers and effective data sharing, so business can adapt when something goes wrong

Modern supply chains

  • Modern supply chains stretch across the world, rely on real-time data and face tougher questions about ethics and sustainability

  • Businesses now use digital tools, closer partnerships and greener standards to keep those long chains working smoothly

Ways to manage more complex supply chains

Way

Explanation

Example

Use live data to trace every item

  • Blockchain tracking lets firms see exactly where food comes from and recall only the unsafe batch

  • Suppliers of fresh spinach and lettuce to US retailer Walmart record field-to-store journeys, cutting tracing time from 7 days to 2 seconds

Predict problems with artificial intelligence

  • AI forecasting spots demand changes and machine failures before they hit the supply chain

  • Nike uses AI models to plan materials and shipping accurately

  • As a result, the rate of late deliveries has fallen significantly

Increase transparency for consumers and investors

  • Publicly available supplier lists and interactive maps show where ingredients come from

  • Nestlé publishes downloadable files naming every coffee, cocoa and palm-oil supplier so buyers can see the full chain

Share IT platforms and paperwork digitally

  • Common data hubs cut time spent on shipping documents and customs

  • Shipping company Maersk was able to shave days off global freight journeys for customers such as IBM by using electronic bills of lading to clear customs quickly

Monitor operations with connected sensors

  • Internet-of-Things (IoT) devices flag faults and energy waste in real time

  • Sainsburys' 600 UK stores are fitted with cloud-linked fridge sensors

  • These save nearly £1m in electricity costs each year and reduce stock replacement costs

Influences on the choice of suppliers

  • Businesses often go to great lengths to find suitable suppliers of raw materials and components

    • Factors including the price, quality and reliability of supplies determine whether a business can efficiently produce high-quality products at a reasonable cost

  • There are several factors that can influence the supplier chosen by a business

A range of factors, including price, quality and reliability impact on the choice of suppliers

Factors that guide the choice of supplier

Factor

Why it matters

Quality

  • Inputs must meet exact standards

  • Poor quality travels through to the final product and could damage the brand

Delivery reliability

  • Late or erratic deliveries halt production lines, especially in just-in-time (JIT) systems

Availability and supply security

  • Businesses need certainty that scarce or crucial materials will not run out mid-project

Price and payment terms

  • Competitive unit cost and favourable trade credit terms keep finished product prices low and cash flow healthy

Ethical and sustainability standards

  • Customers and regulators expect fair labour and greener practices

  • Failure risks scandals, fines and lost sales

Relationship & trust

  • Long-term cooperation supports consistent quality and encourages joint problem-solving and cost-saving

Flexibility & responsiveness

  • A supplier able to vary volumes up or down quickly helps the business cope with demand changes

The value of outsourcing

  • Outsourcing is the process where a business delegates specific business activities (IT, customer support, HR etc) to external service providers

    • Businesses choose to outsource these functions to reduce costs, access specialised expertise, or focus on core competencies

Advantages of outsourcing

The advantages of outsourcing include increased flexibility, access to specialised skills, cost savings, and allows the business to focus on its core competencies
Outsourcing and subcontracting offer a range of benefits to businesses 
  • Cost savings

    • Businesses can often reduce expenses associated with operations such as hiring and training employees, maintaining infrastructure and managing IT systems

  • Access to specialised skills

    • External specialists have resources that the business lacks internally, which allows it to benefit from the knowledge and experience of industry specialists as and when required

  • Increased flexibility

    • They can provide greater flexibility to scale their operations up or down based on demand fluctuations, which is particularly valuable in industries with seasonal or unpredictable demand

  • Focus on core competencies

    • Businesses can concentrate their resources and efforts on their core competencies, where they can add value

Limitations of outsourcing

  • Quality control

    • Using external providers makes it harder to ensure consistent quality and adherence to company standards

  • Loss of control

    • Handing direct control over those activities to others outside of the business may be risky

    • Companies must carefully select reliable partners and establish clear contractual terms to protect their interests

  • Data security and confidentiality

    • Sharing sensitive information outside of the business introduces potential risks to data security and confidentiality

  • Communication and cultural differences

    • Using global providers may result in language barriers or problems with time zone differences. Cultural differences may present communication challenges
