1ISM 6121
- Justifying IT Investments
2Productivity Paradox(Roach, 1987)
- Delivered computing power in the U.S. has
increased by more than two orders of magnitude
since 1970, yet productivity, especially in the
service sector, seems to have stagnated
(Brynjolfsson, 1993) - Returns to IT investments are solidly positive
some have spent vast sums on IT with little
benefit, while others have spent similar amounts
with tremendous success (Brynjolfsson and Hitt,
1998)
3Technology Issues for Financial Executives (Just
released!)
- A small minority, about 10 , believed they were
getting a high return on their technology
investments. - 33 technology was a source of competitive
advantage but also a core competency of the
organization. - 33 technology was neither a source of
competitive advantage, nor a core competency. - 33 viewed IT as a competitive advantage, but
didnt find it a core competency.
4Productivity
- Amount of Output Produced per Unit of Input
- Old Economy
- Output has been measured in terms of Quantity
- Input has been measured in terms of Labor Hours
- New Economy
- Output should be measured in terms of Value Added
- Input should include quality of equipment,
training, supplier relationships, investment in
new processes
5Level of Observation
- Aggregate IT Spending
- Economy Level
- Industry Level
- Findings No Productivity Improvements
- Aggregate IT Spending
- Firm Level
- Mixed Results
- Disaggregate IT Spending (Rai 1996, 1997)
- Software
- Hardware
- Budgets, etc.
- Mixed Results
- Application Spending
- Mixed Results
6Can IT decrease productivity
- Your work will expand according to the time
allotted to do it (Grauer, my entire UG
edcuation!)
7Possible Paradox Explanations
- Mis- measured / Wrong Definitions
- Benefits might be redistributed
- Intra- or Inter- Organizationally
- Passed on to Consumers
- IT does not exist in a Vacuum
- IT spending ALONE may not create Productivity or
other Performance gains - Costs and/or Benefits are Hidden from analysis
- Sociotechnical and Technical Systems are not
Jointly Optimized
8Encouraging Signs
- Brynjolfsson and Hitt (1998)
- Firm Level Data
9Firm Level Analysis
- Increased Sample Size
- Allowed for proxy measurements of Intangibles
- Revenue Increase
- Results
- Spent on IT -gt Revenue
10Lets Analyze the Results
- Revenue Increase is NOT just a result of IT
investment - IT does not exist in a vacuum
- Training
- Process Re-Design
- Organizational Changes
- 50 of IT Effect was firm specific
- Due to Unique Firm Characteristics
- Some have it
- Some Dont
11Organizational Factors
- Costly Time Consuming
- Is NO Instant Gratification
- Returns are not just from IT but
- Systems of IT and Organizational changes
- in IT invested, in Organizational changes
12Summary
- IT Linkage with Firm Productivity
- Computer Investment is Coupled with
- New Strategies
- New Business Processes
- New Organizations
13Mixed Encouragement
- Rai, Patnayakuni Patnayakuni (1997)
- A look at Disaggregated IT Investments
14Measures of IT Investment
- Overall IT
- Capital Stock
- IT Budget
- Client/Server
- IT Infrastructure
- Hardware
- Software
- Telecommunications
- IS Staff
153 Measures of Productivity
- Firm Output (traditional measure)
- Labor Expense
- Total Sales
- Business Results (ROA ROE)
- Intermediate Performance
- Labor Productivity
- Labor Expense / Total Employees
- Administrative Productivity
- Labor Expense / IT Budget
16Results
- All IT Investment Types were related to Firm
Output (Labor Expense Total Sales) - Only IT Capital and Client/Server were related
to Business Performance (ROA) - Cumulative Investments may be reaching critical
mass - Knowledge of use of IT is catching up
- Overall most IT Investments were related with
Labor Productivity - Thus IT reduces Labor Costs and leaves workers
more productive - Overall Most IT Investments were related to
Administrative Productivity - Bad Managers or Bad Decision Making are not
helped by IT - Automated Dysfunctional Management Processes
- Reduce Management Flexibility to Change
- Key
- Redesign Management Processes in Conjunction with
IT Investment
17Wrong Definition
- Thatcher and Oliver (2001)
- Productivity has been confused with
- Production Efficiency
- Improving Product Quality
- Increasing Productivity
18Production Efficiency
- IT enables production of a given product or
service (of given quality) with fewer resources
(Thatcher and Oliver, 2001)
19Quality Improvements
- IT leads to the creation of new products, or new
features for existing products, which directly
increase human desire to consume those products
(Thatcher and Oliver, 2001)
20Productivity Improvements
- IT leads to an increase in the ratio of output
value to its related input value (Thatcher and
Oliver, 2001)
21IT improving Productivity Scenario
- Some Definitions (over simplified)
- Demand Price Quality
- Firm chooses PQ to maximize profits
- Cost Indirect Costs Direct Costs
- Indirect Costs (Fixed)
- e.g. Leases, acquiring, implementing, maintaining
IT - Direct Costs
- Design and Development Costs (Fixed)
- RD, prototyping, usability testing
- Manufacturing Costs (Fixed)
- Variable Costs (e.g. labor)
- To Produce a product requires
- Fixed costs supporting general business
- Cost to design Develop product at some quality
level - Per unit cost to manufacture to meet demand
22Costs and Production Capability
- Technology Investments which decrease
- Design Development Costs
- Unit Manufacturing Costs
- Enhance Production Capability
- Technology Investments which decrease
- Overhead / Business Support Activities
- No Effect on Production Capability
23More Definitions
- Revenue Price Demand
- Moderated by Market size, Price Sensitivity and
Quality Sensitivity - Profit Revenue - Cost
- Productivity Revenue / Cost
24Production Efficiency
- Automation of Overhead (Indirect Fixed Cost)
- Payroll System
- Increases Profits
- No Effect on Price or Quality (i.e. Demand)
25Production Efficiency
- Automation of Design and Development (Direct
Fixed Cost) - CASE Tool
- Increases Quality leads to Increased Demand
- Causes Increased Price creating Increased Revenue
- Increased Demand leads to Increased Production
Costs - Finally if RgtC (assumed), Increased Profits
26Production Efficiency
- Improvement in MFG or Service (Direct Variable
Cost) - On-line Support (reduced variable cost)
- Increases Quality leads to Increased Demand
- Causes Increased Price creating Increased Revenue
- Increased Demand leads to Increased Production
Costs - Finally if RgtC (assumed), Increased Profits
27Technology Investment Productivity
- Automation of Overhead (Fixed Cost)
- Since Revenue Increases and Costs decrease
- Productivity Gain (Efficiency Productivity)
- Automation of Design and Development (Direct
Fixed Cost) - Improvement in MFG or Service (Direct Variable
Cost) - Productivity Gain, if Overhead are Large
(relative to market size), otherwise - Productivity Loss
28Summary
- Greater Production Efficiency from Decrease in
Overhead leads to Lower Costs, Unchanged Revenue,
therefore Increased Productivity - Greater Production Efficiency from Decrease in
Development or Manufacturing Costs, Leads to
Greater Quality (Higher Demand), Increased Price,
Increased Revenue and Greater Production Costs. - If Revenue Increase is gt Production Costs
Productivity Gain - If Revenue Increase is lt Production Costs
Productivity Decrease - Depends of Size of Firms Fixed Overhead Costs
relative to Market Size
29Another New Measure
- Lin and Shao (2000)
- Examining Productive Efficiency
30Production Efficiency
- Production Function
- Maximum Quantity of Output based on
- Combination of Outputs
- Production Efficiency
- Distance between Actual and Maximum
31Productivity Growth
- PG Efficiency Change Technical Change
- Increase in PG Does NOT Necessarily mean
- Increase in Efficiency
- PG could be because of Technical Change
- PG could Decline While Efficiency Increases
- Technical Change is Mismanaged
32Results
- More Spent on IT
- More Productive Efficiency
- Gap Between Actual and Maximum is Reduced
33IT and Top Management
- Tallon, Kraemer and Gurbaxani (2000)
- Examines IT investment from a process perspective
and IT value from Executive Perceptions
34Process Perspective
Management Practices
Strategic Intent for IT
Focused Goals
Firm Performance
Value Chain
Unfocused Goals
35Executive Perceptions
- Instead of Actual Performance/Production Measures
- Use Executive Estimates
- IT Value Creation
36Corporate IT Goals
High
O PE R A T I O N A L E F E C T I V N E S S
Low
High
Strategic Positioning
37Hypothesis
- Executives with more focused goals will have
perceive gt IT business value - Higher levels of strategic alignment gt IT
business value
38Results H1
- Across all Value Chain Activities
- Process Planning and Support
- Supplier Relations
- Production Operations
- Product/Service Enhancement
- Sales Marketing
- Customer Relations
- Dual Focus gt Market gt Operational gt Unfocused
- Perceived IT value
39Results H2
- Significant Positive Correlation between
- Strategic Alignment
- IT Value (for all Value Chain Activities)
40Summary
- IT Execs have different Goals
- Is this surprising after last weeks readings?
- Level of Perceived IT Payoffs is Directly Related
to these Goals - Value Chain Activity most related to Goals are
expected to have the Highest IT Payoff - e.g. Market Oriented Customer Relations
- Operations Oriented ProductionOps
- Firms that used Evaluation techniques and
post-implementation reviews had higher perceived
IT Payoffs
41Social Costs and Benefits
- Ryan and Harrison (2000)
- Examines the hidden costs that might explain
the Productivity Paradox.
42Sociotechnical Subsystem
- Employees and their
- Knowledge
- Skills
- Interrelationships
- Attitudes
- Needs
43Technological Subsystem
44Optimization
- To maximize an Organizational System
- Sociotechnical and Technical Interdependency must
be recognized - Each Subsystem must be designed to fit the
requirements of the other - Small Problems can have big negative Results
- Intervention in one system WILL impact the other
system - Steve Alter()
45IT Valuation
- Usually includes TANGIBLE Technological Subsystem
C/B - Needs to include often INTANGIBLE Sociotechnical
Subsystem C/B
46Research Question
- Are there IT Types that maybe more or less
impacted by Sociotechnical factors? - Does the degree of process change from the IT
have differential impacts related to
Sociotechnical factors?
47Innovation Types
- IT Innovation/Investment Type
- Type I Information Core
- support of IS Work
- DBMS or CASE Tools
- Type II Administrative Core
- Business Functions
- Payroll
- Type III Technical Core
- Embedded in IT for producing Goods/Services
- CAD/CAM, ERP
48Degree of Process Change
- None/Low
- Incremental
- Some/Moderate
- Incremental
- High/Great Degree
- Radical
- Extreme/Total
- Radical
49Interview Results
- Social Subsystem Benefits Identified
- Productivity Improvement (69)
- Few attempted to Quantify this (15)
- Quality (25)
- Intangible Benefit vs. Cost of Quality or
Customer Satisfaction indices - Improved Decision-making ability (17)
- Impossible to Quantify
- Labor Savings
- Tangible Benefits usually included in
Cost-Benefit analysis
50Interview Results
- Social Subsystem Costs Identified
- Training Costs (59)
- Vendor, Materials, External Purchases
- Time Lost (generally not considered We had no
idea what it would be) - Change Management (17)
- Planning, Overseeing, Communicating to E-Us
- Learning Curve / Lag (14)
- Amount of Time Until
- rather than Lost Productivity
51What was Missing? or Managerial Issues
- Increased Role Conflict
- Greater Employee Empowerment
- Better Communication
- Enhanced Interaction
- Employees feelings of Loss of Power/Control
- Employee Morale / Job Dissatisfaction
52Research Question Results
- A clear pattern emerged showing an
Interdependency between - IT Type and Amount of Change
- Greater Weight is given to Social Subsystem C/B
as we move from Type I to Type III - Variation within Type is Explained by Degree of
Process Change - Greater Process Change, Greater Weight given to
Social Subsystem C/B
53Other Findings
- Positive Relationship Between IT and Productivity
- Large Variation Amongst Firms
- Some Spend a lot and get a little
- Some Spend a little and get a lot
- Greatest Benefits Realized when IT Investment is
done in Conjunction with Other Investments - New Strategy
- New Business Process
- New Organizations
