How much can a manager learn from management books?

Thanks for the question.  In fact going to books is something good yet practical and in-house training is a better chance to learn how you can be a leader or a manager at certain times.

Thanks to the invitation, reading specialized books in management can benefit a person a lot but the extent of this interest depends mainly on the desire of the manager and his ability to learn from these books

Thanks for the invitation!

Management books are good to read but a manager can learn more when he is handling a situation,when he is doing work practically, he can learn more as compare to reading books only.

Thanks 

As much as he needs and wants!  

no books might solve a problem it's all about falling and rising.

Thanks for the invitation, 

There is no limitation, once we are ready to learn reference will be more helpful.

The Manager should always walk through in a challenging path. if he doesn't  have that much experience reference will be helpful. and he will get a mental strength while he goes through the management books who share their experiences and be an inspiration.

Moreover, it will be applicable only for those who are ready to learn 

and it will be a supporting material in his practical strategy 

It all depends on the quality of the book and not the quantity. And each of us has his own fault and quality so you have to look for books that work with your quality and flaws. I personally read a book in French (management for the draw) of bob nelson and peter economy and (on becoming a leader) of warren bennis  . essential What you benefit from the books you want to read

Thanks for the invite !!!

I would say about 20% is what can be learnt from books, rest  80% will be learnt when the manager is given a practical exposure.

According to the Director's readiness for education. The subject is not in books but in personal abilities

that based on his learning skills
