!!Do It Once, Do It Right
This is a significant determining factor in Return On Investment.
Maximising the lifetime of the system provides return over a longer period.\\
Minimising the cost of change lengthens the lifespan and minimises maintenance costs.\\
Minimising the cost of change allows you to start with a small working system,\\
responding to requirements and feedback in steps towards the ultimate goal.\\ \\
%%columns
We have seen (as anyone relying on complex systems does after a time) that smaller efforts and working systems (as opposed to big specifications and long timeframes) provide faster, more certain returns, and are not so prone to issues like requirements change or platform evolution (or worse, platform end of life).
\\ \\
The issues with platform evolution (changes to the stack over time) and eventual end of life are critical to tackle if you want to maximise return on investment in business systems software.
\\ \\ \\
The service lifetime of a software program depends on:
* choice of platform (every element of 'the stack' is important)\\
* prioritising future maintenance as highly as feature creation.

%%label-warning A team sport ('the stack')/%
%%quote
Technology - especially software, is a team sport. A software program relies on a 'stack' - other programs and hardware it requires in order to run properly. For example, a complex Excel Spreadsheet is at the top of a stack, requiring a particular version of Excel, a compatible version of Windows to run Excel on, and a compatible PC or Laptop or Tablet to run Windows on. If any of the levels in the stack fail or become incompatible, the program doesnt run anymore - and needs to be maintained or rewritten for the new stack. /%

\\If you do it right, it is possible to avoid the trap that most software falls afoul of - the inability to adapt. \\ \\Requirements change constantly. Software has to keep up or it has to be replaced.
----
%%label-warning Adapt or Perish.../%
%%quote
If the future maintenance of the system is of lower priority than features, the costs per adaptation increases exponentially over the software's lifetime, until the software cannot be economically adapted and must be replaced (the end of returns on that investment).
