Question 23

RECYC Ltd is a medium sized recycling consultancy firm, which is currently experiencing rapid growth. This is evidenced by increased turnover. It has been able to develop a range of new consultancy and specialist business advisory services that it offers to its growing customer base. To cope with these developments, several organisation-wide initiatives have been launched over the past two years.

The existing financial systems are struggling to cope with these developments, but replacement software is due to be installed within the next six months. The new system was justified partly because it could reduce costs, although precise details have not been given. The application software selected does not fit existing business processes exactly. However, it has the clear advantage of giving RECYC access to an industry best practice system and is identical to that used by all its main competitors and some of its clients.

A three-person Project Steering Group has recommended that a phased approach to introduction should be used and has undertaken most of the project planning. A programme of events for implementing the system has been agreed, but is not yet fully operational. This group has not met for a while because the designated Project

Manager has been absent from work through illness. You are Head of RECYC’s Central Support Unit. You also serve on the Project Steering Group.

A Directors’ meeting is due to take place soon. The firm’s Managing Director has asked you to prepare and present a PowerPoint presentation to the other Directors on project management and implementation issues. You understand that the Directors are conscious that system implementation represents a form of further organisational change. They are asking questions about the approach that will be taken to the introduction of the new system, likely changes to practices, critical areas for success, system testing, support after implementation, system effectiveness, etc.

REQUIRED:

(a) List and describe the project management activities and variables addressed by your steering group. (8 marks)

(b) Describe the available options for the systems implementation and explain why a ‘phased’ approach to introducing the system is, in this case, more suitable. (7 marks)

(c) Name and describe the methods you are using to evaluate this information systems project and outline the limitations of financial models for establishing the value of information systems. (10 marks)

Question 24

A teacher training college in the UK has recently expanded very rapidly, introducing a number of programmes and increasing student intake capacity. It has also recently computerised its teaching and assessment processes based on a customised version of some off-the-shelf software. The Library had already been computerised a couple of years ago using a highly functional library automation system that includes multiple catalogs, authority control and so on. Accounts and payroll are handled by computers in the Finance and Accounting department, using popular accounting and payroll software packages.

In order to achieve further improvements in efficiency, the college’s management board asked a team of consultants to assess the suitability of its existing technology infrastructure and information systems to meet its strategic objectives. The consultants advised that the college is burdening itself with too many independent information systems. They strongly favoured an integrated information system on the lines of an enterprise resource planning (ERP) solution for a business organisation.They were concerned that adequate consideration may not have been given to all the areas of operation of the college, or to the strategic oversight of these. In particular they were concerned about the lack of automated procedures for the procurement of everything from laboratory equipment to travel tickets; the lack of integration of the Student Records department with Finance & Accounting (especially in relation to fee payments); and the marketing of the college to potential new students.

The consultants’ report also noted that the directors of the Finance and Accounting department and the Library were both reluctant to change from their existing information systems. The directors highlighted the fact that their departments had recently spent time and money investing in systems that were perfectly adequate for their needs and suited their operating practices.

While the college’s Information Technology department are technically capable of implementing an organisation wide ERP system, they are under-staffed and are highly dependent on key individuals. Management in the department are also concerned that they do not at this time have an adequate hardware infrastructure to support uninterrupted, secure operation of the options being proposed. In fact there has been a history of service outages over the previous six months, all of which were caused by technology failures and some of which resulted in data loss.

Given that management identified 24 hour online access to library resources, e-learning hubs, email and other services, 365 days a year, as essential in the increasingly competitive third level education sector, these outages are particularly worrying.

REQUIREMENT:

You are asked to address the following, based on a critical analysis of the above case study.

(a) Outline the main benefits and challenges for the college and, in particular, the Finance and Accounting department in implementing an ERP system. (8 Marks)

(b) Explain the advantages of using cloud computing services to implement an ERP system for the college. (8 Marks)

(c) Describe the core activities (stages) involved in a project to select, implement and deploy an ERP system in the college. Identify the main issues that need to be addressed during each activity/stage. (9 Marks)

Question 29

Hibernia Ltd., a steel manufacturing company, purchased an information systems package over a decade ago.The system focuses on daily transaction processing of stock, sales and purchasing and provides regular usersummaries. Unfortunately, the output does not provide much of the necessary management information and asa consequence a Co-ordinator downloads output onto spreadsheets which are then manipulated, enhanced andemailed to users. Managers and Senior Managers often complain that even this information is inadequate for theirneeds. In response, Hibernia has employed a business information consultancy firm to conduct a review of itsinformation requirements. The consultancy firm reported that the existing system is outdated and much lessfunctionally rich than more recent software on the market. The main issues and recommendations aresummarised as follows:-

Purchase a new system

Hibernia should purchase a system (called InfoTek) which provides more complete, relevant and timelyinformation. The InfoTek system is easy to understand and navigate and would offer a more comprehensiveanalysis than the existing package provides, including historical statistics and comparison to prices charged bycompetitors. InfoTek also offers potential for further customisation to local needs through its display functions andflexible formats. Users (Senior Managers, Managers and Others) would be able to use the software efficientlystraight away without additional training. Daily transaction processing routines would remain unchanged.

Implementation of the new system

The system should be implemented by direct changeover because Hiberniaʼs network servers have insufficientcapacity to support both new and old systems. The installation should take place over a weekend to minimisedisruption. Once installed, systems maintenance should be minimal.

Redesign of Co-ordinatorʼs role

This role should be redesigned so that the existing post-holder becomes responsible for validating InfoTek output,co-ordinating information enhancements and providing support and advice to users.Hiberniaʼs Managing Director is familiar with InfoTek through past working experience and agrees that it is aworthwhile package. She is, however, unhappy about how the consultants have conducted their review. Inparticular, she is concerned that very few Managers, Senior Managers and other information users have beeninvolved in discussions. She also believes that any job design needs to concentrate on the characteristics of thepost in order to gain maximum motivation and job performance. She therefore treats the findings andrecommendations of the consultants with caution. A fellow Director has advised her not to implement theconsultantsʼ recommendations without further reference to the workforce as this might lead to staff resistance.

REQUIREMENTS:

(a) Discuss the reasons why there may be user resistance to the introduction of the new system and explain thetypes of support that could be organised to help users utilise InfoTek efficiently. (7 marks)

(b) Explain the issues Hibernia should consider before successfully implementing the recommended system. (9 marks)

(c) List and describe the options Hibernia has if they choose not to develop their software in house. (9 marks)
