how to better manage people, sort of is THE question of business.....with graduate degrees and lifetimes of experience and practice its still foggy and a probability exercise at best. Sort of a study in group psychology....and we know how good psychologist are at even figuring out one person.
The task is really to bring out the best in each person. Some random thoughts....
Anecdote. Yesterday morning started riding with a tow truck driver. Chatting and answering questions I explained I had this business, blah blah blah. Later, I had a call with a Sr Project Manager about getting an quote done right away. He saw his day filled with higher priorities. I listened to his concerns and told him stuff he didn't have visibility on came up with a plan. The tow truck drivers says, "you're the boss, why didn't you just tell him get it done". The answer is I need to listen to them as it might be really important and secondly, more importantly I have to treat people properly, listen to them, so that 1) the feel confident to challenge me (that is BEST for the organization) and 2) they feel respected and an important part of the process and company (which they are) So suggestion 1, treat each of your people with respect and listen to their ideas, its how you bring out the best in them.
Are you familiar with the Hawthorne experiment? Its a famous industrial psychology thing on productivity from the '20's - they gradually turned the lights up and found productivity went up. Later when the lowered the lights again, they found to their surprise productivity went up again. At the end of the experiment productivity sagged. The Hawthorne effect then is just the fact that the interest shown in productivity and their environment was the real cause of the gain.
The take away is you being interested, reading and learning and taking an active role in trying to make your management and organizational better, will get noticed and have a positive effect. The Hawthorne thing suggest that ultimately that is more important than what you do - you don't have read the single one 'right book', you just need keep reading and learning so there's a flow of ideas.
So the key is not one course or seminar, but ongoing, read, be interested etc.....better managing is a process not an event. Within business Organizational Behaviour is subject area, there's an endless parade of books on it and management.
Here's the most important bit. Ego. A great manager has a servants heart, which is why there are so few of them. All people have ego needs, to feel good about themselves etc. Because being a manager gives one authority or potential power over others, its the ego's seductive den of iniquity. Maybe the most common flaw of business people. Your ego (sub conscious) wants to look at the mirror in the morning and ask "what can they do for me today". You have to try and force it down and silence it and ask "what can I do for them to day.
Post the stuff you learn so we can too can do better
