The best ways to monitor your Cases are either via Dashboards / Reports, or by using the My Cases Landing Page. You could, for example, create a report that details all the high priority cases that haven't been updated in the last two days, and then put it into a Dashboard, so you can view it easily and in real-time. Alternatively, customise your My Cases Landing Page so that your most important cases are always to hand.
You can record and monitor the relationship third-parties have to a Case, so you can clearly see who's affected by the Case, and therefore share the relevant information with everyone who needs it. You can add relationships from the People and Organisations tabs in a Case record by clicking Add Relationship and then searching for the required record and choosing the relationship from the picklist. You can also define the status of that Person / Organisation (ie, whether they're Satisfied / Unsatisfied, etc).
You can tailor the picklist values to your business needs to maximise the Cases functionality by clicking Start > Configuration > Custom Fields & Picklists > Picklists. The default relationships a Person can have to a Case are:
- Primary contact
- Secondary contact
- Affected user
- Business sponsor
- Third party advisor
