I have a question we have a small company of only 2 QA resource. We follow Agile methodology for QA Testing. For new Clients & enhancements we give the QA estimates and client who are the Pharma company are made aware of the deadlines by the Client service team. In between during the Sprint we get small Adhoc request or Production issues which are for different clients and which are rush item in order to support the current running business. Our current challenge is we have limited QA resources but since the deadline for the new client is not going to be postponed since it was committed and we still need to complete the small adhoc request and production issue.How can we overcome this challenge. I would appreciate if someone can provide a solution. Since this client is a new client we cannot use risk based testing approach.
