Hi,
I could suggest you something for corrective actions coming from audits ( internal-external) but CA can also come from everywhere in an organization.
You can use a dedicated software ( there are lots in circulation) but also xls sheets are usefull to categorize the findings based upon the violated clause ( for example 6.1, 7.5 and so on , related to ISO 9001 or ISO TS ).
You can set a sort of outlook remainder on the mail of the response coordinator that will have ownership to fix and implement action for the realted finding.
Same thing for preventive actions with the same method, also using outlook remainder for decided action of the process owners of the organization , for exampke coming from
FMEA or other risk analysis methods.
In xls sheet you can also have sections for audited processes, monitoring of action completion of the corrective and also to do follow up for effectiveness of the action in a certain time frame.
Anyway lot of software exist and are already programmed for this purpose.
Hope this helps
