Now a days, Chinese authorities are planning to establish strategies for disaster management to counter incidents like coronavirus in the future. They are allocating a massive budget to build automated and semi-automated robotic machines for their hospitals, which can be used by the medical staff to treat the patients with minimum exposure to the fast-spreading viruses. These robots can be programmed to work in the real-time environment for treating the patients carrying deadly viruses. Semi-automated robotic machines can be controlled from the control room by the medical staff. Some high quality software engineering is required to realize these machines so that these can used in the real environment with high precision of control.
Being a software engineer, you are asked to develop a well-engineered software for these machines. If there is a conflict between certain characteristics like Usability, Reliability and Cost of the software; which characteristic will you more prefer for this kind of software? Justify your choice within 4-5 lines with solid reason.
