Part 3  Implementation

     Introduction 

 This chapter reviews new approaches to analysis and design required for  

digital business 

systems

 . It does not aim to explain how to follow  well-  established techniques for analysis 

and design such as data flow diagramming, information flow diagrams and entity relation-

ship diagramming. These have been described many times before, for example in Bocij  et al.  

(2008).     

 The chapter is intended to provide managers with an appreciation of some analysis 

and design techniques for digital business, in particular customer experience management 

through user interface design for desktop and mobile platforms. This familiarity should 

aid collaboration when the managers are involved in discussing the requirements of the 

system with technical staff. It is in two main parts. In the first part we review analysis tech-

niques and in particular process analysis for re-engineering which is important in many 

digital business implementations. We also touch on data modelling and how to manage 

‘Big Data’.

The second part looks at the design of digital business systems. The techniques described 

are aimed at improving the information quality of  end-  users of digital business systems – 

ensuring information is timely and secure, has the correct content in terms of accuracy, 

relevance and completeness, and is in a form that is easy to interpret. The section on archi-

tectural design looks at how systems are integrated to improve flow of information and also 

to achieve timely delivery of information. ‘ Focus on  User-centred site design and customer 

experience management’ demonstrates how using  use-  case analysis and interface design 

guidelines can be applied to produce usable  sell-  side or  buy-  side e-commerce systems with 

good information quality. ‘ Focus on  Security design for digital business’ reviews security 

requirements for the digital business, reviews generic approaches to security and finally 

looks at the current usage of e-commerce security techniques. 

The importance of analysis and design is such that even if an effective strategy has been 

developed, its execution can be destroyed by ineffectual analysis and design. Complete 

Activity 11.1 to review some of the consequences of poor analysis and design.
