Instructions

  1. Ask for missing inputs before proceeding.
  2. For each option, identify all relevant costs (initial, ongoing, opportunity) and benefits (tangible, intangible).
  3. Quantify costs and benefits where possible, using provided data; for intangibles, describe qualitatively.
  4. Calculate ROI, net present value (NPV), or payback period as appropriate.
