These software types depend on the type of your project. For example, in case you're managing a software project, then I can think of 3 software products that can help the quality management of the project:
- Bug tracking software: A software were bugs are reported, tracked, and then resolved.
- Collaboration software: A software that team members and the project manager use in order to exchange information about the project, and where team members facing challenges on their tasks can ask for help from other team members, or where team members building upon code that is written by other team members can inform the latter about errors in their code, or where testers can inform developers about their bugs. (in the latter two cases the collaboration software will act as an expedient bug tracking tool)
- Automated testing software: While there is no substitute to human testing to ensure a very stable end product, automated testing can weed out the most obvious/common bugs and will make the human testing less stressful.
I don't know what software products are used in other industries (such as the healthcare industry) to assist in quality management. I hope someone else who does answers your question as well.
