From ancient times, it has been important to deal with all kinds of unforeseen circumstances and act quickly. Even with a long and elaborate plan, sudden changes can occur.
The emperor was surprised by many enemies during his lifetime. He was forced to respond flexibly many times.
He admits that the empire was dangerous if he made a mistake. With that in mind, he made Snork create a flexible and agile organization. Being smaller than it was in the empire was convenient in that respect.
Consistently from the time of the empire, it was important to achieve the emperor's orders accurately and quickly. However, once the content was announced, it could not be easily changed. The emperor relied heavily on Lord Vader each time, but Vader was also limited. This is why Lord Vader was removed from the ranks of the empire and made objective.
In particular, the slow destruction of the Death Star frustrated the emperor. Despite the tremendous cost of completion, there was clearly a problem with agility. Addressing this issue was an urgent task for the empire. How good would the empire be if the emperor could easily switch to destroy the planet!
The root cause may be that the rule structure became fixed as the emperor continued to take full control. Besides, the size of the organization was too large and there was no opportunity to reform the control structure later.
The solution was for the emperor to disguise his death and have Snork reorganize the empire as a first order.
With the latest technology, we have adopted a flexible system that quickly shifts the chain of command. I'm assuming that Snork is dead or even unforeseen. He made him anticipate the contingency in every respect than the empire. This has significantly reduced the probability that the First Order plan will fail. Transfer command from Snork to Kylo Ren. In the old empire, it's a dysfunction.
All systems that make up the First Order can be switched instantly. In other words, there is no clearly pure concept of a single command tower. All ships are linked at a high level. Complement each other and do each other. Especially the evolution in communication systems and sharing of weapons was tremendous.
Even if it was damaged by an external attack, it was dispersed, so it had the advantage of being able to be quickly minimized. Minimizing damage is important for small troops. Even if Premacy is destroyed, it is possible to quickly migrate the system to Stedfast.
Since it has a small number of weapons compared to the empire, it is a benefit that a high cost can be spent on each battleship. If it is lost or destroyed, it will be a big blow, and each ship is valuable. The loss of the Starkiller base was serious.
Snork carefully devised a Starkiller destruction order and an invasion plan, but was forced to change the timing shortly before. It was the moment when the flexibility of the first order was demonstrated.
