Here are 3 principles from my list of 12. Number 1: test early, test often. Before you do anything, write down the tests for yourself to pass, then test yourself weekly. Write tests for what you are expecting from a class. Make sure that what you are expecting is both In line with the laws of the place you pay Tax and international standards of operation, as explained in the ISO9000/90001 family of specifications. #2, Don’t wait to communicate. Keep asking Good questions both here and on quora about every step of the way. #3, remember “Quality MVC! M is for model, it describes the how to. V is for view, which means the report of execution of that model. C is for control. It’s a record of the controlled execution of your model. Make sure that going forward, you break down your thoughts and actions into Quality MVC, so you can make sure to test against the model in a report that execution was as planned. For more study, please google plan do Check act cycle. Read on lean and six sigma, and be prepared for constant improvement. No matter what classes you take, these three principles will guide you on the path to repeatable, testable, reportable success, beyond a reasonable doubt. If what I say resonates with you, add me, I lecture weekly on business governance and quality control for FREE. I help introduce how to model in standard UML and BPMN, super stupid white board 5th grade simple, and business theory with lots and lots of practice. I sincerely wish You sustainability and lots of good time with your family, cus that’s what matters most.
