Additionally, to integrate the org.scavino.jtwain and meet the requirements, we needed a plan. We applied the Rational Unified Process to subsystem development. Writing our use-case and flows before coding helped us imagine our goal first. Once we created the flows, we designed the API. We wrote the interface to support the steps in our primary flow—no more and no less.

Further enhancements should follow the same process. Given additional requirements, I would write additional flows and see what part of the org.scavino.jtwain API I could reuse and what parts I need to update. This iterative process will allow for managed growth, with each iteration meeting the intended goals.
