Know your sheep by name; carefully attend to your flocks.
If Proverbs 27:3 was written in modern times, it would read "Be meticulous in the execution of your assignments or job".
Being meticulous implies showing great attention to detail or being very careful and precise. It is taking or showing extreme care about minute details. The shepherd, though he may have many sheep, is expected to know not just the general state of his flock but also the state of each sheep in his sheepfold. He is to attend to their varying needs.
O how many have gotten themselves into a fix because they did not bother to read the details of the agreement/contract they signed. Some have run into financial loss because their business plans/ideas were not meticulously prepared. Unchecked bugs in a segment of codes have led to the hours of avoidable debugging of the complete (or combined) set. Confidential documents have fallen into the wrong hands because the person saddled with the task of keeping it safe was careless. Many machines or device are misused and destroyed because its user considered the manual boring.
I recall the story of a satellite that drifted into space, on its launch, instead of moving along its intended orbit, because one of the scientists in the team (carelessly) sent approximated values to the construction team. This simple mistake led to billions of dollar loss. Now our jobs may not have zero error margins like the satellite launch event. Nonetheless, we must be meticulous. We must present data and information as accurately as possible. Put in the effort to know the statistics or reports on what matters at work.
We must integrate redundancy in our designs (where feasible). We must have a fall-back plan if things go awry. A perfect example is how we back-up our data on other independent storage devices as a way of guaranteeing damage/corruption or inaccessibility of our data would not lead to downtime. Also, whatever we do, we must think of all possible challenges that we may face and have a plan to mitigate or eliminate it. The little details matter! Things do not take care of themselves automatically. Leave nothing to chance!
Being meticulous may require more effort and resources (time inclusive), but its gain is unquantifiable. As the scriptures point out, the careless would become poor but the meticulous would get richer (Proverbs 10: 4)
Proverbs 22:29 Seest thou a man diligent in his business? he shall stand before kings; he shall not stand before mean men
Exodus 25: 9 According to all that I shew thee, after the pattern of the tabernacle, and the pattern of all the instruments thereof, even so shall ye make it.
