i am guessing that the quesitonaire you are giving is to measure food safety culture. I have set action level for each question. if the score falls below that level you can / should develop improvements that can be made to raise that particular score. You can also increase the action level as you improve. my plants struggle with questions regarding employee recognition, so we have developed some things to try and improve in this area.
like soup said, the objectives that you develop are also a way to improve. IMO these objectives should be developed for items that your plant struggles with (internal audit scores, first time pass, cleaning completion rate, complaints etc).
you could develop a program where you evaluate different programs each year and research best practices. for example automated continuous monitoring instead of manual (like weight control, time and temp monitoring, vision technology) , improved training and monitoring , increased environmental monitoring / better zoning, etc
you could also research Kaizen, 5s, poke yoke, etc and see if those make sense in your organization.
