The problem

Though the basic need for Investment Appraisal Process was addressed by number of Excel spreadsheets and templates, it was not a sustainable solution for a big business.

Navigator Case Study - Problem

Critical issues

  • Error prone process of collecting project financial data with Excel sheets
  • Lack of transparency in e-mail and Excel based “workflow”
  • Insufficient calculation speed of project and portfolio KPIs
  • Labor intensive calculations of portfolio KPI’s with Excel
  • Very slow and complex investment project portfolio analysis
  • Hard to control underlying project assumptions like oil/gas prices or resources

Growing volume and complexity of projects magnified them and motivated stakeholders to look for better solution. They decided to move the process to fast and easily accessible web application without compromising flexibility of analysis.

The Solution

From business perspective the solution required detailed analysis of existing process and designing it into web application. Scrum based approach helped us a lot with that task.
