EXECUTIVE INFORMATION SYSTEM (EIS) & WORKFLOW MANAGEMENT SYSTEMS (WMS)


EXECUTIVE INFORMATION SYSTEM (EIS)

EIS was developed in the mid-1980s with a primary goal of enhancing the strategic planning and control processes of executives through the provision of quality, timely, accurate and accessible information (O’Brien 1991).

Provided a broad understanding of company information by summarizing large quantities of data and allowed the user to drill down to different levels of data to gain insight into the detail of information.

One dilemma facing the high-quality information requirements of EIS is the fact that data is often input using unskilled and untrained operatives, which may lead to gross errors and misleading analyses.

Careful consideration must be taken to avoid dangers of ‘garbage in, garbage out’ syndrome and potential risk of making the wrong decisions.

Research on the effective implementation of EIS has found number of factors that linked with continuous improvement that can increase the EIS -à
  • Need for a committed executive sponsor to drive project and provide feedback on the product quality and expectation
  • Need for a pro-active operating sponsor, to act as market researcher with the executives, confidence builder, product designer and operational line manager
  • The bringing together of business knowledge and IT skills through framework
  • Coordinating systems and processes lower in the organization with EIS to ensure alignment of effort
  • Visually attractive graphics


WORKFLOW MANAGEMENT SYSTEMS (WMS)
  • One of the ideal tools in business process re-engineering
  • Part of enterprise resource planning (ERP) and consider as the back-office integration processes in organization.
  •  An important function of WMS is the modelling of workflows. WMS can be seen as repositories of an organization’s procedures and process.
  • They are predominantly suited to the efficient processing of a large number of ‘cases’ within a small number of predefined process.
  • With a separate workflow defined each case more likely to occur in future developments of WMS
  • Example cases; customer orders, insurance claims, university application and tax returns. However, each cases has a unique identity and a limited finite lifetime.
  • Task in a WMS are logical units of work such as writing reports and assessing candidates, and can be manual, semi-automatic or automatic.
  • The combination of a task and a case is termed a work item and the application of a task on a case is seen as an activity. Besides that, there are number of ways that a case can go through a process and this determines the nature and order of the tasks to be performed.
  • This routing of a case may be   à

-          Sequential
-          Parallel
-          Selective

There are traditional and formal analysis of processes is use of ‘PETRI NETS’ – enables processes to be described graphically and is composed of places and transition.




This to ensure precise definitions of processes and prevent ambiguities.
Circle – places indicate states within a process
Rectangle – transition may denote different activities between states
*Places and transitions often linked together using arcs shown by the arrows

Besides that, to develop standards with the multitude of WMS, the Workflow Management Coalition (WFMC) was set up to define terminology and provide standards for exchange of data between different systems. The WFCM has produced a workflow reference model as a general description of architecture in WMS. 

In addition, there are different aspects of WMS:
1. Workflow enactment service
2. Process definition tools
3. Workflow client application
4. Invoked application

5. Administration and monitoring tool




There are 2 methods of developing WMS using business process re-engineering (BPR) or rapid application development (RAD).

1. BPR – aims to discover the most efficient and effective business processes without resource to existing processes. 
However, BPR lifestyle is initiated by senior management and contains 4 phases:
1. Diagnosis
2. Redesign
3. Reconstruction
4. Operations

2. RAD – uses more evolutionary method for developing WMS and has a strong emphasis on user participation. 
The RAD approach comprises 4 phases
1. Requirements planning phase
2. User design phase
3. Construction phase
4. Delivery phase
