Minor League / Major League.
What I have attempted to show you to date is a significant part of the development cycle. It is all geared to you as a Manager to gather your thoughts and to communicate to you IT Professionals your requirements specification.
But you can do more - you can learn UML and gain a real appreciation of just what is involved when you begin to analyse and develop business processes.
It is my belief that to support your data modelling you should review the UML process and create your own UML Lite to to support your own development.
This is a learning process for myself - during my career in computing I have worked on at least two projects which were a great success due to investing in creating a methodology / documentation process to match the requirements. One was a significant traditional waterfall development where the analyst created diagrams to represent the various transactions which where required - This was an extension of HYPO which was the departments standard. The second example was a set of documents designed to support analysis and programming of a packaged product - with documents closely resembling the development IDE.
UML Lite is an interesting project which you yourself should undertake to improve your communications.
Areas of Learning : SSADM - Structured Systems Analysis and Design / Prince2 (PRojects IN Controlled Environments), could be evaluated and might influence your design.
All of the above is Minor League stuff - you, with a little energy, are more than capable of achieving great things.
The following link is Major League stuff - the realms of highly qualified IT Professionals :
A GitHub - Where you will find program source.
It will take you years of hard work to reach these heights - impossible without support and mentoring.
