Hello Everyone,
In our current project we are 6 developers and do absolute time based estimation i.e. 2 SP is one day and Sprint duration is 4 weeks(20 business days). So we plan approx. 200 SPs (according to calculation 240 = 2*20*6) with 40 SP with buffer. But we are noticing from last two Sprints that we are able to finish approximately 160 SPs and now the Product owner wants to know the reason for decrease in the output for the last Sprints as it is clear that even with buffer we should be able to achieve minimum or approximately 200 SPs. How do i handle it?
