Organisations without a BYOD policy have the benefit of selecting a small number of devices to support, while organisations with a BYOD policy could also limit the number of supported devices, but this could defeat the objective of allowing users the freedom to completely choose their device of preference.
Do you know that when talking about puppies, most trainers and behaviorists consider a puppy to be a dog that is just born to about 6 months of age? This may be a bit confusing because many of us have been told over the years that a dog is a puppy until about 1 year of age.
Also, the time that a puppy reaches sexual maturity and is capable of reproducing is often considered to be a pivotal age point, but again, sexual maturity does not mean that any given dog should be considered an adult, and they will almost certainly have a lot of growing and maturing left to do.
