ACA is software for conducting Adaptive Conjoint Analysis studies over the Internet, or using devices not connected to the Internet (CAPI-based) data collection. ACA is part of Lighthouse Studio. For more general information about ACA, we suggest that you read the "ACA Technical Paper" available for downloading from our home page at www.sawtoothsoftware.com.
ACA is an older adaptive conjoint technique that was quite popular in the 1980s and 1990s, but is not used as often today as CBC or ACBC. Yet, for certain purposes, it is still a useful conjoint analysis method. ACA has its weaknesses, however, and the researcher should become familiar with those weaknesses and the differences between ACA, CBC, and ACBC to ensure proper usage.
A sample ACA questionnaire (tut2.ssi) and supporting files are available within your installation of Lighthouse Studio. You can easily access this example study by clicking Help | Sample Studies. This questionnaire lets you see an example of an ACA survey and investigate how it is set up.
If you know a little HTML (which is not necessary to use ACA), you can employ some "tricks" that will help you customize the look of your survey beyond the standard options provided by the software. By opening the sample study and looking at the settings and text we've used, you can become familiar with some of the possibilities.
