Why grow a business

Why grow a business?

  • Many firms start small and will grow into large companies or even multi-national corporations

    • For example, Amazon and Dell both started in entrepreneurs' garages

Reasons why businesses grow

  • The owner's or manager's desire to run a large business & continually seek to grow it

  • The owner's desire for higher levels of market share and profitability

  • The desire for stronger market power (monopoly) over its customers and suppliers

  • The desire to reduce costs by benefiting from lower unit costs as output increases

  • Growth provides opportunities for product diversification

  • Larger firms often have easier access to finance

Internal business growth

Internal business growth

  • Internal growth that is driven by organic expansion using reinvested profits or loans

  • It is usually achieved by:

    • Gaining a greater market share

    • Product or market diversification

    • Opening new outlets

    • International expansion (new markets)

    • Investing in new technology or production machinery

Examples of internal growth

Business

Explanation

Apple

  • International expansion (new markets): Apple expanded into new markets by opening its stores in new countries, such as China and India, and by partnering with telecom providers to sell its products.

Google

  • Product innovation: Google introduced new products, such as Google Drive and Google Maps, to complement its search engine and advertising businesses

Disney

  • Product diversification: Disney has diversified into several areas, such as theme parks, cruise lines, television networks and movie studios.

  • Product diversification opens up new revenue streams for a business

    • Firms may spend money on research and development or innovation to existing products to help create a new revenue stream

  • Firms often grow internally to the point where they are in a financial position to integrate (merge or buy) with others

Evaluating internal growth

Advantages

Disadvantages

  • The pace of growth is manageable

  • Less risky, as growth is financed by profits and there is existing business expertise in the industry

  • The management knows and understands every part of the business

  • The pace of growth can be slow and frustrating

  • Not necessarily able to benefit from lower unit costs (e.g. bulk purchasing discounts from suppliers) as larger firms would be able to

  • Access to finance may be limited

External business growth

External business growth

  • External business growth is when a business expands by joining with or buying other businesses rather than growing on its own

    • A merger occurs when two or more companies combine to form a new company

      • The original companies cease to exist and their assets and liabilities are transferred to the newly created entity

    • A takeover occurs when one company purchases another company, often against its will

      • The acquiring company buys a controlling stake in the target company's shares (>50%) and gains control of its operations

Vertical integration

  • Vertical integration refers to the merger or takeover of another firm in the supply chain or different stage of the production process

    • Forward vertical integration involves a merger with or takeover of a firm further forward in the supply chain

      • For example, a dairy farmer merges with an ice cream manufacturer

    • Backward vertical integration involves a merger with or takeover of a firm further backwards in the supply chain

      • For example, an ice cream retailer takes over an ice cream manufacturer

A firm can grow through forward or backward vertical integration, merging or taking over another business within the supply chain
A firm can grow through forward or backward vertical integration, merging with or taking over another business in the supply chain

Evaluating vertical integration

Advantages

Disadvantages

  • Cuts production costs by removing middlemen

  • Lower costs increase competitiveness

  • Greater supply chain control and more reliable access to raw materials

  • Better control over raw material quality

  • Forward integration increases profit and brand visibility

  • Diseconomies of scale (e.g. duplicate management roles)

  • Culture clash between merged firms

  • Lack of experience in new business area may reduce efficiency

  • High acquisition cost may take time to recover

Horizontal integration

  • Horizontal integration is the merger or takeover of a firm at the same stage of the production process

    • For example, an ice cream manufacturer merges with another ice cream manufacturer

Evaluating horizontal integration

Advantages

Disadvantages

  • Rapid market share growth

  • Lower unit costs from economies of scale

  • Less competition

  • Shared industry knowledge improves success chances

  • May gain new expertise

  • Diseconomies of scale (e.g. duplicate roles)

  • Culture clash between merged firms

Problems of business growth

Problems of business growth

  • In some cases, growing the size of a business can fail to improve its profitability and can lead to cash flow and coordination problems

Problems and solutions of business growth

Flowchart illustrating problems of growth: larger firms harder to control, poor communication, high costs causing cashflow problems, merger difficulties.
Businesses are often faced with a range of challenges when they grow

Poor communication

  • Longer chains of command and wider spans of control for managers may lead to slower decision-making times and inefficiency

Solution

  • Use the latest communication technologies, such as instant video calls, to improve communication between managers and workers 

  • Decentralisation may help to delegate decision-making

Larger firms are often harder to control

  • As a business grows in size, it can experience diseconomies of scale such as poor co-ordination of resources

Solution

  • Operate as a series of smaller units which allows local or functional area managers to have more control

  • Increase delegation in order to empower workers and get jobs done more quickly

High costs and cashflow problems

  • Expansion can be very expensive as it may involve developing a new product range or buying a new factory

    • High costs in the short/medium term means the business may need additional finance to avoid cashflow problems

Solution

  • Grow slowly using profits rather than loans to fund gradual and less risky expansion

  • Manage cash flow carefully, making use of retained profits and short-term borrowing to counter cash flow shortfalls

Difficulties of mergers and acquisitions

  • A culture clash may occur if a merger or acquisition  takes place between two different firms due to different management styles

Solution

  • Ensure good communication so employees are less likely to be resistant to change

  • Take time to carefully negotiate and plan mergers/acquisitions to reduce 'teething problems'
