  7. 7. Value Net Model<br />Competition<br />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. <br />Customers<br />“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. <br />Suppliers<br />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. <br />GIKA<br />Influencers<br />Product sales can be influenced by organisations that review products, use of interior designers, etc. <br />This can directly influence the stocks, designers and brands supplied to customers. <br />Word of mouth in services and product ranges can also influence. <br />
