Perhaps you can share your experience with others here, explaining how you do it...with all your experience. That is the idea of this forum, after all?
i am sure with all your experience you could put your 2 cents in as well,
but in the mean time
how to follow multiple open orders,
1- get professionally trained in "order flow management"
2- get professionally trained in "time management"
3- get professionally trained in "project management"
*the above should take you 6 years full time if your good longer if not
5- then open your own business and run that for a minimum of 5 years
6-bringing us roughly too 11 years to complete, if your fast.
7- after you have completed the above successfully you would have gained the experience and knowledge you require to track multiple open orders.
I suppose it's a good analogy, useful too with transferable skills; but not essential for success in respect to that it must be done. At the end of the day everything here is open to interpretation, and it's the qualuty of the interpreting that makes the difference.
