Cost benefit analysis
To decide between alternative solutions, cost-benefit analysis can help you make the right decision. It can be challenging to quantify the effect. It requires the ability to see the complete picture and how the change affect the overall business.
Six Sigma focus on gathering neutral information and make fact-based decisions. Six Sigma's problem-solving method DMAIC follows these steps:
- Define: Select the right projects and collect data to understand the problem
- Measure: Map the current situation and baseline the process
- Analyze: Identify root causes and analyze data to prove / disprove them
- Improve the process by implementing and verifying the best solution
- Control the new process by maintaining the solution.
The improve phase of Six Sigma identifies different solutions and calculate the effect of the different alternatives. To make the right decision it is important to evaluate pros and cons and calculate the cost-benefit effect of the various alternatives.
It does not need to be 100% correct, 90% is usually more than enough to make the right decision. Six Sigma includes prioritizing tools and is well suited for cost-benefit analysis.

"We are very happy with the work carried out. We was not very clear what the order was, but with your background and expertise the outcome was what we were looking for and a document we will benefit from in the future"
"We hired Lean Tech to develop monitoring program for air emission. The monitoring program should satisfy requirements from the Norwegian Environment Agency including sampling frequency to ensure representative samples, uncertainty estimates, calculations and preparation of reporting templates, etc. The assignment was delivered with the correct content at the right time. Recommended." 
"Sissels ability to quickly understand the issue, as well as her commitment and expertise is impressive. Her analytical and thorough contribution to our monitoring program has been precise and targeted, and very educational. "
