Andy1968,
First, tacking on to an old thread is not the best way to get quick help. You could have started a new thread and then referenced this thread as one approach.
But down to your call for help: The truth is that Access isn't ALWAYS the correct solution. In some cases, other utilities might be better. EXCEL isn't bad. Tedious, maybe, but not terrible. Having said that, it is possible to do this with Access but you will most likely only be able to use a limited subset of the power of Access for organization.
For the columns where you have risk choices like None, Low, Medium, High, Impossibly High, etc., you can use a combo box to fill in such things. I see several other columns where you appear to have some kind of drop-down selector, so you can streamline the choices and normalize the dataset to isolate the various lists of choices from the main body of the individual risk table. That normalization will help shrink the amount of data to keep per risk entry and will allow you to build reports that are either project-centric, risk-type centric, or frequency-centric.
Much of what you are going to have to do is to manage text-oriented data entry for the detailed description columns or select options for each header you need to track. Normalization will help with the select process. Text data entry? You're on your own for that part.
You also need to define your end goals for this project. To do any serious computations, your bosses or your actuaries will have to assign risk levels to the the choices for that column. You should be able to search the web for "risk analysis" and "risk mitigation" as topics. TRUST me, there is wealth of data out there in the web. The U.S. Navy used this heavily for new project analysis and, since we were a hosting site, new service analysis.
If you are heading towards doing what the Navy did, you have a list of risks. You need to identify for each one the kind of risk (and you have several check-boxes for that), probability of risk (you call it priority, I think), detailed nature of risk, actual dollar value of risk IF IT HAPPENS, frequency of risk (one-time or recurring and if the latter, how often), cost of mitigation, effectiveness of mitigation, cost of ignoring, effect of ignoring, etc.
From such things you can compute what each risk costs you to ignore or to mitigate after-the-fact or to partly or completely prevent (if possible). If this is like any of the risk matrices I have seen before, your goal will be to roll up or otherwise summarize the project risk as an annual cost/benefit ratio so that you can assign a budget to a mitigation staff or in some other way refine the overhead costs of taking on certain types of projects. Which means your business sales group can "sharpen their pencils" to better estimate overhead costs on future projects.
I have worked with this kind of analysis but this is usually something more oriented to a project manager type to define the terms and assign values where possible. I had to sit in on some new-project initial risk assessments which is why I know as much as I do about it but I expressly DO NOT claim to be an expert on the subject.
