WHAT IS THE ONE MOST IMPORTANT FACTOR IN ANY SUCCESSFUL BUSINESS ?1.KNOWLEDGE 2.LUCK 3. CHANCE 4. RESOURCES 5.TACTICS 6. MANAGEMENT ?

All these factors have their due value but I believe in present scenario Knowledge is most important which acts as a lever to other factors.

Out of six mentioned here,, Knowledge is the most important. Knowledge helps me to utilize resources effectively and tactfully, which leads to successful management. By doing all the three successfully, opportunity (chance) and Luck automatically follow me.

I would add Leadership and put them in order as mentioned below:

1- Leadership

2- Knowledge

3- Management

4- Tactics

5- Resources

KTM : Knowledge Tactics and  Management are the most important

 All the mentioned factors  are important but I will vote for management .Although Some people will say if you are lucky you will get all the other factors

Great Question

I would like to choose management first with tactics industrial engineering techniques because only management can run the good business with all tactics, knowledge and manage available resources or produce required resources for successful business. 

All of the above apply, but the most important is the KNOW-HOW. Knowing to use and combine all the above is the key. 

Knowledge and management

using knowledge and tactics to manage the given resources for taking chance with luck.

Knowledge definitely... Luck is not infinite and runs out :)
