Digital Strategy: formula sheet

Key formulas

Digital strategy (definition)

Digital strategy = business direction + digital technology + data + customer value

Use as a one-line definition. It is a business plan, not a technology list.

Digital transformation (definition)

Digital transformation = changes in processes + people/culture + business model, enabled by technology

Stress that technology alone is not transformation.

Key contrast

Digital strategy = business-led, 'what and why'; IT strategy = technology-led, 'how to support'

The most-asked difference. Back it with points such as scope, ownership, focus and time horizon.

Business model components

Business model = Value proposition + Customers and channels + Operations and resources + Revenue model

Use these four parts as a checklist to describe any digital firm.

Value creation for the customer

Customer value = Benefits received − Cost to the customer (price, time, effort)

Digital tools raise benefits (choice, personalisation) and reduce cost (time, effort, price).

Network effect

More users on one side → more value for other side → more users

A reinforcing loop. Applies to platforms, not to every online business.

Main digital revenue streams

Sales, commission, subscription, advertising, freemium upgrade, transaction fee, data services

Link each model to its revenue stream in answers.

CIA triad

Confidentiality + Integrity + Availability

Use it to classify any cyber threat and to structure the control you suggest.

Risk = Likelihood × Impact

Risk level = Likelihood of event × Impact if it occurs

A common way to rank risks. It is a prioritisation idea, not an exact money figure unless values are given.

Risk response options

Avoid | Reduce | Transfer | Accept

Reduce means controls and training. Transfer means insurance or outsourcing. Avoid means not doing the activity.

Control types

Preventive | Detective | Corrective

Firewall and access control prevent. Monitoring and logs detect. Backups and incident response correct.

People-process-technology

People + Process + Technology

A safe frame for challenges and mitigation. Cover all three to avoid a one-sided answer.

Quick revision

• Digital strategy is the plan; digital transformation is the organisation-wide change that delivers it.
• Digital strategy should support business strategy and not sit as a separate IT plan.
• Digital business models create value through data, platforms, convenience and network effects.
• Platform models connect two or more groups, and value grows as more users join.
• Each emerging technology should be remembered with its use, benefit and limitation.
• Strategy formulation starts with understanding the environment and setting digital goals.
• Implementation needs leadership support, skills, process change and budget.
• Monitor results against set measures and adjust the plan.
• Cybersecurity risks include data breaches, malware and phishing; controls include access control, encryption and staff training.
• Resistance to change and skill gaps are common people-side challenges.
• In MCQs, read all four options; no negative marking, so always attempt every question.
• In written answers, use headings, short points and one example to earn step marks.

Common mistakes

• Treating digital strategy and IT strategy as the same thing Fix: Remember that IT strategy supports the business, while digital strategy shapes the business model and customer value.
• Defining digital transformation as just computerisation Fix: Always mention processes, culture and business model along with technology.
• Treating every online business as a platform. Fix: A platform connects separate user groups and relies on interaction between them. A firm selling its own goods online is direct e-commerce.
• Naming a model but not the revenue stream. Fix: Always add how the firm earns: commission, subscription, advertising, transaction fee or sales.
• Only defining the technology and not linking it to strategy Fix: After every definition write 'so the firm can...' and name a strategic gain such as lower cost or better customer experience.
• Mixing up big data analytics and AI Fix: Remember: analytics finds patterns in data to inform human decisions; AI learns from data and can predict or decide on its own.
• Treating digital strategy as buying software or an IT plan. Fix: Always state the business goal first, then the technology that serves it.
• Not showing alignment with corporate strategy. Fix: Write a line for each initiative saying which corporate objective it supports.
• Treating digital risk and cyber risk as the same thing Fix: State that cyber risk is a subset. Digital risk also covers failed projects, vendor dependence, data quality and change resistance.
• Listing risks without mitigation Fix: Write every risk with a paired control. Use the preventive, detective, corrective split.

Exam tips

• Expect 'distinguish' and 'short note' questions; prepare a ready comparison with at least four parameters.
• In MCQs, watch for options that reduce transformation to tools only; these are usually wrong.
• Always give one Indian example, such as a bank app, e-commerce or a manufacturer using data.
• Link the answer to competitive advantage, since this is a strategic management paper.
• Keep definitions in your own words and in the first two lines.
• Always give the model name, the revenue stream and an Indian example. These three earn most of the marks.
• For MCQs, look for the key signal: two connected user groups means platform; recurring fee means subscription; free plus paid tier means freemium.
• In long answers, use short headed points: value proposition, technology, revenue, challenges.
