Chapter 12 Implementation

1. Chapter 12Implementation

2. Learning outcomes • Produce a plan to minimize the risks involved with the launch phase of an e-business application • Define a process for the effective maintenance of an e-business system • Produce a simple web page with links to other pages • Create a plan to measure the effectiveness of an e-business application.

3. Management issues • What actions can we take to minimize the risks of implementation? • How do we achieve transition from previous systems to a new e-business system? • What techniques are available to measure the success of our implementation?

4. Implementation • The creation of a system based on analysis and design documentation.

5. Implementation Activities • The creation of the system modules by coding and scripting • Module integration • Testing and changeover to the live system

6. Maintenance Phase • Commences after system is live

7. Dynamic e-business application • The application is continuously updated in response to competitive forces.

8. Maintenance Activities Involves • measurement of an information system’s effectiveness and • updating to correct errors or • introduce new features necessary to improve its value to the organization.

9. Relationship between analysis, design, implementation and maintenance

10. System implementation issues • Acquisition techniques • Site implementation tools • Content management and updating • System changeover • Localization • Evaluation and monitoring.

11. Figure 12.1Sequencing of implementation and maintenance for the dynamice-business application

12. Acquisition Method • Defines whether the system is purchased outright or developed from scratch.

13. Systems acquisition options • Bespoke development. The e-commerce system is developed from scratch. • Off-the-shelf (packaged). An existing system is purchased from a solution vendor. In the e-business context this approach is often achieved by external hosting via an applications service provider. • Hosted Solution . Standard software that is managed externally on the supplier’s server. • Tailored off-the shelf development. The off-the-shelf system is tailored according to an organization’s needs.

14. Development of web-based content and services • Static web content • Dynamic web content • Knowledge of HTML- creating a simple HTML page • Forms • Page Layout

15. Figure 12.3Possible web page layout options

16. Developing Dynamic Web Content • Scripting Languages • Client side scripting • Server side scripting • JavaScript, VBScript, Perl, ASPs, .Net

17. Figure 12.5Using scripting to produce dynamic web content for form processing

18. Testing Has 2 main objectives: • To check for non conformance with the business and user requirements • To identify bugs or errors

19. Test Specification • A description of the testing process and tests to be performed.

20. Testing

21. Different tasks involved in maintenance • Write • Review • Correct • Publish(to test environment) • Test • Publish( to live environment)

24. Management issues with maintenance • Deciding on the frequency and scope of content updating • Process for managing maintenance of the site and responsibilities for updating • Selection of content management system • Testing and communicating changes made • Integration with monitoring and measurement systems • Managing content in the global organization.

25. Measuring and Improving Performance of e-business Systems • Create performance management system • Define the performance metrics framework • Tools and techniques for collecting metrics and summarizing results

26. Figure 12.8A summary of the performance measurement process

27. Figure 12.9The five diagnostic categories for e-marketing measurement from the framework presented by Chaffey (2000)

28. Figure 12.10Attrition through e-commerce site activities

29. Tools and techniques for collecting metrics • Collecting site visitor activity • Hit • Log file analyser • Page impression • Unique visitors

30. Figure 12.11Examples of different measures of visitor volume to a web site

31. Selecting a web analytics tool • The types of data that need to be integrated within the performance management system: Operational Data Tactical Data Strategic Data • Web Analytics tool should integrate various data sources.

33. Summary • Implementation is an iterative process of managing changes involving analysis, design, testing and review as part of an evolutionary prototyping process. • Maintenance is a continuous process of monitoring, assessing required changes and then implementing them using evolutionary prototyping.

34. s • Simple web pages are developed in static HTML. Most e-business systems require dynamic pages that are implemented using client- and server-side scripting, of which the most popular are JavaScript and ASP.

35. Testing has two main objectives: first to check for non conformance with the business and user requirements, and second to identify bugs or errors. • There are many specialized techniques to test either part of the system or all of the system.

36. Content management requires a clearly defined update process and responsibilities according to different types of changes required. • Measurement also requires process and responsibilities and also a measurement framework.

37. Selection of appropriate web analytics tools is important to assess the effectiveness of e-commerce.
