In context of the organisation I am familiar with, I will discuss Nolan’s six Stage hypothesis (1.2- 1.4-6)and ward and Griffith’s model (1.5 to
1.1 Background - The company I will be discussing is Duboutique. Duboutique is a Big retail fashion store that has ladies Men’s and Children’s department. The retail unit grew from using the old system of manually writing invoice and issuing receipts to customer to using a cash register system. The system duboutique was using was the type that only allow sales items to be typed and the receipt is printed out to the customers like a “type writer”, it is not connected to the computer. The Company introduced a New system called EPOS “Electronic Point of Sale” where data is captured at the time and place of sale. The system is integrated in the computer registers with a bar code readers, optical scanners and magnetic stripe readers for accurately and instantly capturing the transaction, Credit card and debit card transactions that go through a ‘swipe’ machine are dealt with via an integrated EFTPOS. The system is connected directly to a central computer so that they can check the credit of the customer and to update the stock control. The information system covers wide areas of activities in the firm, it, made all activities in the company efficient . The new information system is at the sixth stage on the nolan’s hypothesis (maturity stage)
1. 2 Introduction - I will be discussing in full details with reference to the Nolan six stage hypothesis how the “new point of sales system” was introduced into Duboutique, the stages it went through before it reach maturity stage. I will Show in my discussion that each stage is a learning process and it is used as a planning process.
1.3 The stages - Furthermore, Nolan's six stage hypothesis validates a stages of growth model for the evolution of Information Systems Planning. Nolan suggested that the growth of information system in an organisation can be divided into four stages: initiation, contagion, control, and integration. Subsequently, Nolan added another two stages, data administration and maturity, thereby creating a six-stage model (Nolan, r.l. 1979). The models assume that predictable patterns exist in the growth of organizations Information technology system. The stage hypothesis on the assimilation of computing technology provides one of the most popular models for describing and managing the growth of administrative information systems.
1.4-1 The Initiation stage - The new computerised “check out point of sale system” was introduced into the company at this stage the old point of sale “type writer” system was still in use in the shop by the check out personnel in various departments. The new system was very expensive and it is used by the Top managers of the company, all the sales record collected from the old system is inputted into the new point of sale. Not everyone has access to the use of the technology at this stage.There is an emphasis on functional applications to reduce costs.
