# SCAR Advantage > We find the decision costing an organisation the most money, fix it in 30 days, and make sure it does not come back. SCAR Advantage is a decision intervention practice led by David Maclean and Mike Jansen, based in Cape Town, South Africa, with engagements globally. The practice works on one inherited decision that keeps stalling, escalating or reopening, and measures four things: decision speed, trigger to decision (Day 30), execution speed, decision to completed action (Day 30), executive escalation (Day 30) and financial impact verified by finance (Day 90), baselined at intake with the client finance function. ## Pages - [Home](https://scaradvantage.com/): What SCAR Advantage does - [The 30-Day Decisive Loop](https://scaradvantage.com/30-day-intervention): What the four-week intervention delivers, and how it is measured - [Worked examples](https://scaradvantage.com/results): Case notes across mergers and acquisitions, private equity and business rescue - [Worked example](https://scaradvantage.com/dashboard-example): An anonymised 30-day impact report - [Applications](https://scaradvantage.com/applications): Where the method applies - [Investment](https://scaradvantage.com/investment): Engagement terms and fees - [About](https://scaradvantage.com/about): David Maclean and Mike Jansen - [Gulf](https://scaradvantage.com/gulf): Practice notes for Gulf engagements - [FAQ](https://scaradvantage.com/faq): Common questions - [Contact](https://scaradvantage.com/contact): Bring us the decision - [Terms](https://scaradvantage.com/terms): Site terms ## SCAR Papers - [The most expensive decision](https://scaradvantage.com/paper/most-expensive-decision): Foundational paper on inherited decisions and decision drag - [The deal closed.
