| Style | Pros | Cons |
|---|---|---|
| Conditions | 1. Nice GUI for creating simple conditions. 2. GUI well documented and understood by support team |
1. Only supports simple comparisons and does not "AND" and "OR" conditions well. 2. Cascading conditions work erratically 3. Slow - database intensive -it can slow down long surveys. 4. Some reported problems with reloading conditions. 5. GUI doesn't scale well when there are dozens, hundreds, or thousands of questions. 6. It could be slow to convert paper-based surveys since it must use SGQA names. 7. Often need a programmer to custom-code logic needed for complex branching. |
| Relevance | 1. Supports very complex logic, including 80+ functions and math/string operators. 2. Perfect support for cascading logic. 3. Fast - no extra database calls, supporting 1000+ question surveys. 4. No problems with reloading logic since it does not require SGQA codes. 5. Syntax-highlighting scales to 1000+ question surveys. 6. Easy and fast to use for groups wanting to computerize existing paper-based surveys. 7. It easily supports semi-structured interviews and epidemiological surveys without needing a programmer. |
1. No GUI for simple conditions - it makes use of syntax-highlighting instead. |
