c$)$ You are asked to design the wall mounted matt finish bathroom mirror cabinet $453615cm$ white PPCP $($see Figure $1).$ This mirror unit contains $5$ screws, $3$ ancher and $1$ cabinet. Each part of the chair is manufactured within the tolerance of $+-0\mathrm{.}1cm.$ Apply system engineering approach $($three parameters design$)-$ identify and sketch the elements under each design parameter. $[$Hint: list the bill of materials$]$

Then justify how scalability, reliability, availability, and maintainability are addressed for the system approach.
