someone please answer these questions
You are a financial analyst for a mid-size architectural firm
with some 100 employees located in three cities across the United
States The firm consistently earns over $30 million in annual
revenue by providing engineering and design services that cover a
variety of structures and systems, from building brand new
facilities to renovating and rehabilitating those that already
exist. It specializes in providing exceptional design services for
HVAC, electrical, piping, fire protection, and lighting systems.
The firm currently has a perpetual license for state-of-the-art
computer-aided design and drafting software for its 50 architects
and engineers at a cost of $6,000 for each copy. The software is
periodically in need of software patches to fix bugs and/or
security issues. These are provided at no additional cost. However,
there is a $400/year charge per user for technical support. Patches
are centrally managed and applied each quarter to all copies by a
member of the firm’s IT staff. This typically requires that an IT
support person spend about 1 hour with each user and their
computer. The software manufacturer provides a major new release
every three years at an upgrade cost of $4,000. You have been asked
to evaluate the advisability of moving to a software as a service
solution and paying a monthly fee $300 per user that includes all
technical support, software support, and upgrades to new
releases.
