Does R&D efficiency mean local efficiency?
What does local efficiency mean? A department should improve efficiency, test efficiency and development efficiency. Local efficiency improvement can not fundamentally improve the delivery speed. If you want a requirement to be delivered quickly and smoothly, you need to shorten the blocking time of this red part when considering the efficiency of R&D, that is, shorten the cooperation time between various functions. Therefore, it can be seen that the improvement of R&D efficiency does not only refer to the improvement of local efficiency.
Does R&D efficiency mean efficient delivery?
If the technical ability can't keep up with the engineering ability, then the efficient delivery may face worse and worse software quality, more and more technical debts, breakdowns or system crashes at any time, which is not the efficiency we pursue.
Does R&D efficiency mean continuous and efficient delivery?
There seems to be nothing wrong with it. Continuous and efficient delivery means that my technical ability has improved and I have achieved real fluency and efficiency. In addition to continuous efficiency, we also need to pay attention to whether the delivered content has commercial value and whether the business is successful.
To sum up, what needs to be improved in R&D efficiency is the ability to deliver effective value continuously, steadily and with high quality.
