The phrase means that a work which can be done by one person, if done by a group never ends with a good result.... It always leads to mixture of ideas and acts and thus the thing takes its wrong way...... So a work should be completed by the no of persons needed to do it......
Many women have their own idea of how a recipe should be cooked how long it should be cooked and what ingredients belong in it. So sometimes for example like on holidays or at parties when a large number of people get together and the women gather to cook, it gets confusing.
One person might start cooking something, and then another thinks it needs something added. Then another one gives her opinion, and on and on. Suddenly the original dish is some strange concoction. Thus they say too many cooks spoil the broth. The combined efforts of the group end up with something that is not so peasant to eat.
I think the same term is often applied to situations not related to cooking. In essence often there are too many people telling other what to do, so no one really knows how things are suppose to be.
A good example would be five different people showing a young child the proper way to tie a pair of shoes. Maybe all of them have a way that works for them, but the child might get so confused by the different ways that he or she can not do it in the end.
The complete proverb is "Too many cooks spoil the broth." This means that if you have too many people involved in a project, they will often ruin it. The truth of the proverb can be seen if it is applied to its original subject, cookery: if two or three people each see themselves as being in charge of preparing a particular dish, they will probably each add seasoning, for instance – resulting in an over-seasoned dish.
This proverb contrasts with another, equally famous one: "Many hands make light work." However, they are both true. The problem summed up by the "too many cooks" saying is one of demarcation; who is in charge of what. One person's work is not better done if two people take a hand in it. On the other hand, if you have a large or complicated task, the more people who will help you with it, the better.
Too many cooks spoil the broth means that if too many people try to do the same thing together,they end up ruining it.If you have too many cooks trying too cook one broth or soup,they get in each other' s way and end up adding wrong things.
The old adage that 'too many cooks spoil the broth' can be broadly applied to many areas in life. Too many mechanics, too many workers, too many people with opinions and work ethics, that make decisions complicated. As a cook can have a recipe for an excellent soup, another cook may have their own recipe, however if both put the seasonings in according to their own recipe, the soup will not be good, because too much seasoning has been applied. Too many bosses is also a problem. Each may have a technique to solve a problem, but if there is confusion over the differences, than little will be accomplished, or the result will not be sound. Too many people on a job site, will get in each others way, thus slowing the progress of the project. There needs to be one boss who makes the final decision, that will be clear to the employees, thus avoiding confusion and mistakes. So just as with the cooks and the soup. One recipe, or formula, needs to be applied by a knowledgeable supervisor.
