The following steps will allow you to determine optimal concrete mixture proportion values:

1. Specify Responses -- You specify the responses and desired performance criteria for your project.

2. Specify Mixtures -- You specify the factors (mixture components) to be varied, their ranges, and material properties needed for mixture proportioning (e.g., specific gravities, absorptions, etc.)
   After Steps 1 and 2 are complete, COST will automatically generate a set of trial batches (an experimental plan) for you.

3. Run -- You run the experiment (batch, fabricate, and test) according to the plan generated by COST.

4. Input Data -- When the experiment is finished, you enter the results into COST.

5. Analyze -- After you enter the experimental results, COST will analyze the data for you.

6. Summarize -- After analysis is complete, COST will summarize the main conclusions of the analysis and provide optimal mixture proportions for you.
