The effectiveness of post-bureaucracy

Drawing from any examples from your own
experience, please write a post about the effectiveness of postbureaucracy. You may like to consider the following:
In what ways have these organisations reduced bureaucracy?
Why do you think they have done this? For example, what
problems did they have with bureaucracy, or what advantages
do you think they hope to gain from removing bureaucracy?
How do the organisations deal with specific HR functions such
as pay, performance management, and recruitment and
selection?
Can you see any problems or disadvantages from removing
bureaucracy from the organisations?
Can the organisations completely remove bureaucracy
