ISYS90038 Chap.2 The IT Value Proposition
The IT Value Proposition
Week 2 asks whether an organisation is able to use IT to its best advantage, and it treats the relationship between the business and IT as part of the answer. The old value proposition, replacing clerical labour with machines, no longer explains modern IT spending, because large investments have no guaranteed effect on profit and IT's contribution is woven through other people's work.
McKinsey's 2017 survey adds that many business leaders now see IT as replaceable by outside providers unless CIOs raise their influence. Value is subjective: executives, operational staff and IT each define success differently, and the textbook asks for win-win outcomes rather than gains for one group at another's expense.
Value also moves through three stages, identifying potential value, converting it through people and process change, and realising it, and it arrives slowly along a W-shaped path over three to five years. Peppard's image of IT as an island, cut off from day-to-day business conversation, is the relationship failure the practice exam asks you to find in a case.
The chapter closes with five principles for delivering value, from portfolio management and small chunks of value to joint ownership and frequent experiments, and a worked case on a hospital network whose new system went live on budget and changed nothing on the wards.
What this chapter covers
- 01
The value proposition: whether an organisation can use IT to its best advantage
- 02
Why the old proposition fails: large investments, indirect returns and the silver bullet assumption
- 03
Subjective value: executive, operational and IT views of success, and the win-win test
- 04
Three stages of value: identifying potential, converting it, and realising it
- 05
Peppard's island: no liaison role, informal links and unreconciled definitions of success
- 06
The W effect: an investment dip, an adjustment dip, then payback over three to five years
- 07
Five delivery principles: portfolio review, chunks of value, holistic view, joint ownership, experiments

Find island evidence in a council's IT unit
- 1Define the island: an IT function with little day-to-day connection to the business, so neither side understands the other's needs.
- 1Check for a liaison role: contact happens once a year through the budget round (P3, L4–6), so no ongoing liaison exists.
- 1Cite behaviour: library staff buying their own software (P5, L2) is the duplicated effort an island produces.
- 1Cite the measure gap: success reported as availability (P6, L9) differs from what service areas need, so value definitions are unreconciled.
Key terms
- IT value
- How useful and how wanted IT is in one specific organisation, closely tied to its business model and judged differently by different stakeholders.
- W effect
- The W-shaped path of value from an IT investment: an investment dip, early recovery, an adjustment dip, then payback over three to five years.
- IT island
- Peppard's term for an IT function cut off from the business, with almost no routine contact with the people it serves.
- Chunks of value
- Smaller, lower-risk projects that return value quickly, preferred to one large transformation.
- Portfolio value management
- A process that reviews IT funding periodically and stops projects that are no longer viable.
- Joint ownership
- Shared responsibility for an IT initiative between business sponsors and IT, including executive sponsorship of major projects.
- Silver bullet assumption
- The discredited belief that technology alone produces immediate business results.
The IT Value Proposition FAQ
Why is IT value described as subjective?
Because executives, operational staff and IT judge success by different measures, from cost savings to ease of daily work to system stability. The textbook therefore asks organisations to define value broadly and to look for outcomes that benefit every group.
How long does it take an IT investment to pay back?
The Week 2 material describes three to five years along a W-shaped path, rather than six to eighteen months. An early rise usually reflects finishing the technical work, and a second dip follows while the business adapts to using the system.
What evidence shows IT is an island?
Look for the absence of an ongoing liaison role, coordination that depends on informal personal contacts, and projects where IT and the business measured success differently without reconciling the two. The last is usually the strongest evidence in a case.
Who is responsible for delivering IT value?
Not the IT department alone. Value comes from people, processes and technology together, so business managers share responsibility, and the textbook expects executive sponsorship for every major initiative.
Exam move
Learn the chapter as a diagnosis kit. For value questions, write down at least two stakeholder views and show a decision that serves both. For island questions, practise the branching structure: check for a liaison role, then cite the strongest evidence, then state the consequence. Sketch the W-shaped curve from memory and label each dip, so you can argue that early disappointment may be the adjustment phase.
Finally, match each of the five delivery principles to a fix you could recommend in a case, such as a relationship manager for joint ownership or a pilot for experimentation.
