1 Introduction2 Website Purpose Before analyzing the quality of Blackberry's website and investigating value creation, it is important to be clear about the purpose of the website. How a company uses its website is part of the business strategy.2.1 Introduction to the purpose of the websiteAccording to Tassabehji (2003-83) there are four main reasons for using a website: dissemination of information, acquisition of data, promotions and marketing and transactions with interested parties. Two of these purposes for a website apply to Blackberry.com. First of all, a company website could guarantee the dissemination of information. The information can target different stakeholders: shareholders/investors and customers (Tassabehji 2003-83). In the case of shareholders and investors, information on the website may include annual reports, company news and business plans. The situation is different when the target is customers, as they will be more interested in product information, support and resolution of questions. Secondly, Blackberry.com also uses the Internet for promotions and marketing. Online promotions and marketing are available in different ways (Tassabehji 2003-91). Tassabehji (2003-91) distinguishes six different ways of online promotion and marketing: banner advertising, affiliate programs, search registration, email newsletters and traditional marketing strategies.2.2 Blackberry.comThe main purpose of Blackberry.com is the dissemination of information, mainly to customers, but also provide some interesting information for shareholders. Blackberry.com provides a lot of information to the customer online, including: product specifications, different types of support, interactive demos, manuals... half the sheet of paper... With these two methods, Blackberry.com encourages its customers to resolve the difficulties themselves, as a result Blackberry can reduce the costs for service personnel. In addition to the online service, Blackberry also offers many services via mobile network operators, as the Blackberry contract is often combined with a network contract. Although the most difficult technical problems will still be solved by the Blackberry factory itself, the simplest problems can be solved by the operators. This again results in cost reduction for Blackberry and could be seen as an efficiency resource.4.2 New4.3 Lock-In4.4 ComplementaritiesComplementarities are created when one resource gains more value when combined with another resource (Zhu 2004). The value of the two resources together is greater than the sum of the two resources separately.
