Executive Summary
The Squandered Computer shatters the widely held corporate myth that spending more money on Information Technology automatically results in higher productivity and increased profits. Written by Paul Strassmann, a former CIO of the Department of Defense and Xerox, the book serves as a wake-up call to executives.
Through exhaustive analysis of financial data from thousands of companies, Strassmann argues that there is zero statistical correlation between a firm’s IT budget and its financial success. Computers are merely accelerators: they amplify existing competence or incompetence. To stop squandering capital, businesses must align technology strictly with business strategies and measure success through Information Productivity and Return on Management.
The Core Thesis
IT spending does not equal competitive advantage. Strassmann’s central thesis is that the value of information technology is not inherent in the hardware or software, but in how effectively management uses information to achieve strategic goals.
- The Productivity Paradox: Heavy IT investments frequently yield no measurable financial returns.
- Amplification Effect: Good management uses IT to scale efficiency. Bad management uses IT to generate reports faster while masking systemic failures.
- Alignment over Expenditure: Success is dictated by business alignment, not the size of the IT budget.
Why this happens: Companies often buy technology to fix organizational problems. Putting a new computer system on top of a flawed process only makes the flaw operate at the speed of light.
The IT Spend vs. Profitability Scatter Plot
Strassmann’s data revealed a random scatter: high IT spending does not guarantee high profitability.
Core Pillars & Concepts
Information Productivity
Standard productivity measures, like widgets per hour, fail in the knowledge economy. Strassmann defines Information Productivity as evaluating how effectively management creates economic value above the cost of capital.
Why it matters: It shifts focus from hardware efficiency to human management effectiveness.
Return on Management (ROM)
A revolutionary metric that measures the value added by management relative to the costs of management. If an IT system is installed but ROM decreases, the technology has squandered resources.
Why it matters: It holds executives accountable for IT investments, rather than blaming the IT department.
Business-IT Alignment
IT cannot be an isolated silo. Technology strategies must be a direct derivative of business strategies. If the business goal is customer retention, IT must be evaluated solely on how it improves retention.
Why it matters: It prevents the “technology for technology’s sake” syndrome.
The True Cost of IT
Hardware and software licenses are just the tip of the iceberg. Hidden costs—training, downtime, organizational disruption, and managing complexity—often consume the theoretical ROI.
Why it matters: It exposes the hidden drain on corporate budgets.
The Myth of the CIO
The CIO should not be merely the chief mechanic for computers, but a business leader who understands capital allocation, information economics, and strategy.
Why it matters: It realigns IT leadership with executive business goals.
The Outsourcing Trap
Outsourcing IT to save money is often a symptom of bad management. If a company does not understand its own information processes, outsourcing just pays a third party to mismanage them.
Why it matters: It prevents catastrophic loss of internal business knowledge.
Powerful Analogies & Case Studies
“Paving the Cow Path”
AnalogyThe Concept: If a cow creates a wandering, inefficient dirt path to reach a pond, and a city paves that exact path with asphalt, it has not solved the inefficiency—it has made a bad route permanent and faster.
The Application: Companies do the same thing when they buy expensive IT systems to automate existing, inefficient business processes. Instead of re-engineering the business, they use technology to do the wrong things faster.
Information as Food
AnalogyThe Concept: Consuming massive amounts of food does not make a person healthier; health depends on nutritional value and the body’s ability to metabolize it.
The Application: Generating massive data and reports does not make a company smarter. Information only has value if management metabolizes it into actionable, profitable decisions.
The U.S. Banking Sector (1980s-90s)
Case StudyThe Concept: Banks were among the earliest and largest adopters of computer technology, pouring billions into mainframes and networks under the promise of massive productivity gains.
The Application: Despite leading the world in IT spending, the industry saw little aggregate productivity growth. Technology often cancelled itself out in competitive stalemates, proving hardware investment alone does not generate economic value.
Chapter-by-Chapter Synthesis
A meticulous breakdown of Strassmann’s logical progression, explaining how he builds his case against blind IT spending and constructs a new framework for Information Productivity.
Chapter 1: The Productivity Paradox
Key Concepts: Introduces the Solow Paradox: you can see the computer age everywhere but in the productivity statistics. Strassmann establishes that the assumption “IT = Profit” is flawed corporate dogma.
Examples/Data: Analysis of major companies shows scatter-plot charts with effectively zero correlation between IT budgets and shareholder returns.
Chapter 2: The Illusion of Technology Economics
Key Concepts: Distinguishes Technology Economics, such as MIPS, storage costs, and hardware speed, from Information Economics, which measures business value.
Examples/Data: Judging a business by its technology speed is like judging a taxi business solely by the top speed of its cars while ignoring whether drivers can find paying customers.
Chapter 3: Return on Management (ROM)
Key Concepts: The heart of Strassmann’s financial framework. Because IT is a tool used by management, the only way to measure IT effectiveness is to measure management effectiveness.
Examples/Data: If an expensive ERP system is installed but management’s ability to generate surplus value drops, the system squandered money regardless of how fast it runs.
Chapter 4: The True Cost of Information
Key Concepts: Exposes the hidden iceberg of IT costs. Capital expenditures are only a fraction of Total Cost of Ownership; the real costs include maintenance, training, support, downtime, and disruption.
Examples/Data: A company may buy a low-cost PC but spend many times more over the asset’s life on networking, helpdesk support, and user configuration time.
Chapter 5: Information Workers and Bureaucracy
Key Concepts: Explores how IT often inflates bureaucracy instead of reducing it. Technology lets managers generate endless requests for data and reports that no one reads.
Examples/Data: The “paving the cow path” metaphor captures how technology can institutionalize bureaucratic inefficiencies.
Chapter 6: Aligning IT with the Business
Key Concepts: IT strategy cannot exist in a vacuum. It must be subordinated to business strategy. If the business lacks clear strategy, every IT investment is a gamble.
Examples/Data: IT departments often build elegant technical solutions that solve problems the business does not actually have.
Chapter 7: The Risks of Outsourcing
Key Concepts: A severe critique of outsourcing IT purely to save money. If you outsource a chaotic, poorly understood process, you lock in the chaos with a long-term contract.
Examples/Data: Companies that hand over core data operations can become unable to innovate and trapped by expensive change-request fees.
Chapter 8: Knowledge Capital
Key Concepts: Shifts focus from physical capital to Knowledge Capital: the accumulated know-how of employees. Technology is only a vessel; knowledge generates economic value.
Examples/Data: Replacing experienced workers with software can destroy invisible knowledge capital, creating long-term decline despite short-term savings.
Chapter 9: The Role of the Executive
Key Concepts: Redefines who is responsible for IT failure: not only the IT director, but the CEO and board when they treat technology as “nerd stuff” they do not need to understand.
Examples/Data: Executives can doom ERP implementations by approving technology without changing the incentives of the managers who must use it.
Chapter 10: Remedies and Prescriptions
Key Concepts: Offers a roadmap out of squandering. Stop funding IT projects based on technical necessity alone; every IT dollar must be tied to measurable economic value.
Examples/Data: Technology is a magnifier. Before buying the magnifier, ensure you have something worth magnifying.
Conclusion
The Squandered Computer remains profoundly relevant today. While technologies have evolved from mainframes to cloud computing and AI, Strassmann’s fundamental truth remains unchanged: technology cannot fix bad management, and buying more technology does not buy a better business.
By shifting focus from hardware metrics to human effectiveness—measured through Return on Management—Strassmann provides a timeless toolkit for ensuring that every dollar spent on information technology serves the economic goals of the enterprise.
