Adobe adobe.com Slack assists Adobe with resolving service requests (e.g., customer calls or partner requests on bugs, fixes and other issues). It allows Adobe to track tickets by assigning case numbers to every service inquiry we receive and track the issue to the resolution. It can distribute tickets according to priority and subject matter while giving top-level dashboards and reports on things like overall resolution time and productivity spikes. Adobe customers tend to seek support in a variety of ways (e.g., by phone, email, text, social media messaging or via community platforms). Slack also helps Adobe with omni-channel routing which allows Adobe to filter requests that come in through the different channels and get them to the right customer care support function. To provide these services, Slack may process some limited personal data (such as name, age and date of birth) and details relating to business activities (e.g., the context of the support issue they are helping to route).
