# How is "Behind by"/Ahead calculated for iteration plan

 0 Aradhya K (1.4k●4●43●45) | asked Oct 16 '12, 1:25 a.m. JAZZ DEVELOPER  - Create a PA based on Formal process template - User_a's work is allocated 100% to Plan_A - User_a's work from Mon - Fri and 9AM - 5PM - No absence - Plan_A starts from 1/Oct/2012 and ends 31/Dec/2012 = 66 working days - Assign only one WI Task1 to User_a and the estimate time is 180 hours My understanding is that the "Expected work hour" per day is 180 hours / 66 days = 2.727 hours If the spent time of Task1 is 0 hours at 9AM on 2/Oct, the "Behind By" is shown as "-2.75 hours".   If the spent time of Task1 is 0 hours at 17PM on 5/Oct, the "Behind By" is shown as "-13.75 hours". This is what I expect.  Now I changed the work allocation to Plan_A of User_a to 50%.  However the "Behind By" is still shown as "-13.75 hours". While Task1 is 0 hours at 17PM on 5/Oct, if I set User_a's "Scheduled Absence" from 1/Oct until 2/Oct, the "Behind By" is shown as "-8.5 hours". (2.75 h * 3 days = 8.25)    According to my test result, work allocation doesn't affect to "Expected work hours" but "Scheduled Absence" does.  Is this working as designed? Also please let me know how the fraction is treated. (e.g. in the above case, "Expected work hour" per day is 180 hours / 66 days = 2.72727.. hours)
