Importance of IT performance measurement
“If you cannot measure it – you cannot manage it. Without systematic
measurements, managers have very little to guide their actions other than their own experience and judgement”
10
Enterprise Systems – Horror stories
• Geneva Steel declared bankruptcy after going ‘live’ with a 8 Million SAP system
• FoxMeyer ‘invested’ USD 65 Million on SAP and declared bankruptcy
• SAP implementation at HERSHEY (project cost – USD 112 Million, 19% loss of production and delays during the Halloween season). 2000-Q3 profit increased by 23%
11
Importance of measuring IT performance
1. It is the most important question for IT executives?
2. It’s a BIG investment
A typical ERP installation has a total cost of approximately USD 15 Million
By 2006 ERP market = USD 70 Billion
12
Importance of measuring IT performance
3. Despite the big investments, there are drawbacks of ES
• Deloitte Consulting (Survey of 100 companies)• The study identified that about one third (37%) of the
companies reported significant and quantifiable benefits from their ES investments. 15% of the companies studied, believe that they have received ‘nothing’ out of their ES. 25% of the organizations have received modest results of the ES, and they are not positive about gaining higher benefits. The remaining 23% had been unable to report any specific benefits
13
Importance of measuring IT performance
4. Allocate future investments in Information Technology(Do you need to upgrade – do you need to reengineer business process)
5. Understand stakeholder needs and perspectives(Way of grouping people in the organisation)
7. Simply to understand the benefits of IT (ES)
14
Measuring ES Success / Performance
ES generate Financial (Quantitative) and
Non-Financial (Qualitative) results, making it
difficult to clearly see the gains of the
system, thus a comprehensive measurement
method is needed, to evaluate the
performance of the ES
15
2 Methods of measuring ES success
• There are two main methods• Objective measures
Mainly based on financial indicators Examples: Return on Investment, Net present Value
• Perceptual measures Based on attitudes, perceptions of individuals Examples:, Accuracy of Information, Individual
performance improvements
17
Cameron and Whetton 7 questions of evaluating ES success
• Cameron and Whetton (1983) identified 7 questions that need to be answered when evaluating ES success and organizational effectivenss. These questions are:
1. What is the perspective? 2. What is the domain of activity? 3. What is the level of analysis? 4. What is the purpose of evaluation? 5. What is the time frame employed? 6. What types of data are to be used? 7. Against what referent is effectiveness to be judged?
18
Q1. From whose perspective is effectiveness being judged ?
• Independent stakeholder • Individual user • A group of people• Project manager• IT management • Owner/senior management• Society
19
Q2. What is ‘the system’ being evaluated?
• part of an information system (e.g., GUI)• one particular system (e.g., the HR module)• a type of system (e.g., ERP)• all IT applications in an organization• an inter-organizational information system • an IT implementation process (e.g., ASAP)• the IT function in an organization
20
Q3. What is the level of analysis?
• Organizational level analysis and/or• Functional level analysis
22
Q5. What is the time frame is employed?
• Short term (e.g., “on time and within budget” for implementation projects)
• Long term
23
Q6. What type of data to be used?
• Objective measures Tangible figures that can be measured using formulas
or calculations Mainly based on financial indicators Example: Cost - Reduce errors
• Subjective measures intangible measures They are evaluated through methods such as
interviewing staff for their opinions and views of the system.
Example: Staff Dissatisfaction - Customer Satisfaction
24
Q7. Against what referent is effectiveness to be judged?
Compared to: • some other organization (benchmarking) • some ideal level of performance • past performance of the organization• other desirable characteristics
26
Enterprise Systems success models
• IT Balanced Scorecard
• Delone and McLean (1992) IS success model
• Shang and Seddon ERP Benefits framework
• Organizational performance frameworks• Malcolm Baldridge National Quality Award• European Foundation for Quality Management• Deming Application Prize• IT Capital gain using Tobin’s Q
Balanced Scorecard
• The Balanced Scorecard (BSC) is a technique developed by Kaplan and Norton (1992).
• Balanced scorecard – A strategic planning and management system enables organizations to clarify their vision and strategy and translate them into action
Balanced Scorecard
• Balanced scorecard views the organization from four perspectives Financial Customer Internal business process Learning and growth
The Original Delone and McLean’s IS Success Model
• In 1992, DeLone and McLean proposed a model of IS success as shown below:
The Original Delone and McLean’s IS Success Model
• McLean’s IS success model identified six interrelated dimensions of IS success: System Quality: measure of the information processing system
itself
Information Quality: measure of information system output
Information Use: measure of recipient consumption of the
output of an information system
User Satisfaction: measure of recipient response to the use of
the output of an information system
Individual Impact: measure of the effect of information on the
recipient
Organizational Impact: measure of the effect of information on
organizational performance.
The Updated Delone and McLean’s IS Success Model
• As the IS success model that was originally proposed needed further validation, DeLone and McLean also proposed an updated model.
• The six dimensions of the updated model were1. System quality2. Information quality3. Service quality4. Intention to use, Use5. User satisfaction6. Net benefits
The Updated Delone and McLean’s IS Success Model
The differences between the two models
• The primary differences between the original and updated models included:
1. They have added the service quality variable to show
the importance of service.
IS move from production function to production & service
function => importance of service quality
2. Adding a measure for user attitude, i.e. intention to use
3. Impacts on whom? Individuals, groups, org., industry,
economy => Net Benefits dimension with contextual
definition
