What Is a Business Case?

BUSINESS CASE: FINANCIAL CONSIDERATIONS

Measuring Financial Consequences

Return on Investment (ROI) // Kapitalrendite

> Measuring how much of your invested „money“ you get back in return.

Net-Present-Value (NPV) // Kapitalwert

> Sum of all revenues and payments including interests.

Break-even-Point // Gewinnschwelle

> Point in time when accumulated costs and revenue are equally large.

Example Case – New Car-Insurance Inventory

Ricola Insurance creates new Car-Insurance Inventory

Project duration: 12 months

Project costs: 5.000.000 SFR

Earnings after launch:200.000 SFR each month

Project lifespan: 5 years

Agile As In Scrum

Relevant for financial

consideration

> Iterative and incremental

development (Sprints)

> Prioritized requirements

(Backlog)

Agile As In Scrum

Not considered with potential positive impact

> Higher team productivity (intrinsic motivation, self-organisation, …)

> Reaction to changes

> Including new ideas

> Stop project in time (all features implemented; cancel project)

Possibly neutral through automation

> Frequent migration & deployment

Not considered with potential negative impact

> Impeded productivity through frequent releases (for users)

> More trainings

> Higher operating costs through running systems in parallel
