6. Business Environment Analysis

7. Value Net Model Competition Pricing strategies- competition can play hard ball in charging customers for products. After sales service quality can have a effect in what GIKA can provide. Customers “Consumer is King” - they have a high bargaining power, enabling them to chose and play GIKA and other competitors against each other. The solution enables them to have a lot more channels of distribution and cost cutting methods. Suppliers Suppliers bargaining power can be argued, this is because firms want to sell cheaply, they can be looking out for more options and better cost cutting relationships with them. GIKA Influencers Product sales can be influenced by organisations that review products, use of interior designers, etc. This can directly influence the stocks, designers and brands supplied to customers. Word of mouth in services and product ranges can also influence.
