FAQPage Schema
How do I calculate NPV and ROI to build a business case for a project investment?

To build a business case, identify one-time and recurring costs, map benefits to objectives, and calculate NPV, ROI, and payback. This structured cost-benefit analysis determines financial viability and justifies the investment with a defensible recommendation.

What is the best way to categorize benefits when doing a cost-benefit analysis?

The best way to categorize benefits is mapping every identified benefit directly to a business objective using Winter's Benefits Map. This ensures your cost-benefit analysis remains strategically aligned and defensible when justifying project investments.

How do I determine the payback period and total cost of ownership for technology initiatives?

Determine the payback period by identifying and categorizing one-time and recurring costs to establish total cost of ownership, then weighing those against mapped benefits. This calculates when the investment recovers its costs and yields structured ROI metrics.

Can I use a cost-benefit analysis for both process and product project decisions?

Yes, you can apply cost-benefit analysis to project decisions across product, process, and technology initiatives. It systematically weighs costs against benefits to provide a structured recommendation on whether to proceed in a given business context.

When do I need a formal cost-benefit analysis for investment justification?

You need a formal cost-benefit analysis when justifying investments by determining their financial viability and strategic value. It is required when you must outline costs, categorize benefits, calculate ROI, and present a defensible recommendation to stakeholders.

Why does my project business case fail to show clear financial viability?

Your business case may fail to show financial viability if it lacks a rigorous cost-benefit analysis. Without identifying total cost of ownership, mapping benefits to objectives, and calculating NPV and payback, the investment justification remains undefensible.
