Q:Q: (Initially posted on 8/5) FROM MENTEE LAUREN S. IN CT
I was on a programming team for my FIRST robotics team, and I saw how much work and how much time can be put into just to make a light blink on and off regularly. So, how long does it take for someone experienced to program a computer, never used, to operate?

Good question, Lauren. When something is being programmed for the first time,
it DOES take a long time to make sure it works in all situations. These days,
once a new concept is developed, it is patented and often sold as a package.
That way, it doesn't have to be "re-invented" more than once! Most companies
create new products combining third-party software (software written and sold by
another company) unless the company wants to improve on the functionality. If
there is a new feature to be added, this takes time to write requirements for
the feature (EXACTLY what should this new functionality be - should the light
blink in patterns, or be changeable by the user? and how does a user change how
it blinks? Is performance important? what color?), write the design ( what kind
of computer should the software work on? what language - Java? C++? what
should the software interfaces be?), program the code, test it thoroughly, test
it again. And again. Test until everyone is satisfied that this new feature
meets the requirements. Then, package it and patent it and sell it! Depending
on the size of the new feature, this could take anywhere from 1 week (maybe the
feature demands a very small change ) to 1 year or more (maybe it's a brand new
computer that has multiple new features or enhancements)! Normally, new
features and new functionality is created by more than one person. So, one
person does not have to have expertise in all areas. There is a systems
engineer who writes the requirements, an engineer who writes the design and
codes the product and tests it, another engineer who may test it and pass it on
to another tester. Meanwhile, someone is patenting the concept. Another person
is creating the packaging and the marketing strategy. Some of these roles are
occuring in parallel so that the feature gets to market as quickly as possible.
