Explanation:
The score of Sachin in consecutive five innings at 80, 90 ,100, 100 and M respectively.

There is often confusion on what good engineering managers and leaders should do. Engineering Management is sometimes conflated with architecture and code delivery, where communication, people and culture take a backseat. Engineering Management is NOT about architecture and implementation. While the engineering team proposes, influences and evolves the architecture of products that deliver to a Company's vision, the true ownership of the architecture and implementation lies with the Company. It delicately rests on the fabric of communication between the various functions within the Company such as Sales, Sales Engineering, Support, Services, Product, Operations and in some cases Education Services and Community Enablement.
