Software Development Review from Niclas Manson B.Kin, MPH, CRSP, CIH, ROH
SDTC has been developing custom software for Manson Methods Inc. They have delivered good products but still required robust testing and fixes due to bugs. SDTC staff are very good at taking informaiton and delivering the vision. There have been times where they delivered feature but did not match our vision. I believe this is a fault of our not being clear enough or providing details or pictures to help with the vision. I also find the delivery times were a littel slower in august and september vs June and July. Overall I am very satisfied and hoping the feedbacks cna be implemented.
