Action item should be agreed between customer and PL WIKI Meeting Task List or Task Management System Register action item to Task Process

Module 1. Task Management Task Management ,[object Object],[object Object],[object Object],[object Object],[object Object],[!] Requirement can be separated into more detail sub requirement System Task Sub Task Description Requirement N/A Detailed functional requirement. Requirement cannot contain any child requirement. It is leaf node of requirement tree. Name of requirement has to have number to provide traceability. Ex) 2.1.1 Logging inbound transaction WorkingItem Working items for developer. Eg. Coding,debugging etc. Documentation Write deliverables as document on wiki or document Test Develop and execute test of “ Requirement ” . It includes implementing Unit Test,design, execute etc. Meeting Meeting about specific issue Bug N/A Bug reported by somebody(not a author) after every internal release phase.

Module 1. Task Management Task Management ,[object Object],[object Object],Open Scheduled In Progress Resolved Closed ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],PL PL PL PL Customer Based on technical use case. Extract Child requirement and register it into JIRA Scheduling child requirement based on iterative development. It is linked to WBS in this phase In Every iteration, when the requirement related sub-task is started, change status to In Progress After finishing all of sub tasks for the child requirement. Change the status to “Resolved”

Module 1. Task Management Task Management ,[object Object],[object Object],Open Assigned In Progress Resolved Closed PL Need more Information Postponed PL creates detail task for developer. Task is usually finished 1~4 day. (1~2 days are recommended) Discuss with developer and estimate time. Assign the time to task Developer Developer Developer Developer PL PL Developer discuss with PL PL lets developer to postpone the sub task. The postponed task should be finished in same iteration phase. Or closed
