Should all managers know how to create a strategy?

Managers should know strategic planning to solve problems in their day to day jobs. However, ability to create company strategies comes with maturity, experience in relevant field...

Yes Manager should implement the strategy by day to day and also his subordinate also.

Not anly managers. We all need to be able to build our own strategy, not only at work, but also in our personal life.

It is very important to define clear goals for your team and to have a good plan of how to get their.

Yes ofcourse

Agree with the answer given by  Salauddin Mohammad  ,Sr. Project Manager

Yes all manger should be able to create the strategic plan, vision and mission as well, most of the people are creating strategy in their personal live, and it is very important to implement controlling function to see if their is any deviation to be fixed. 

yes it is, being a manager, strat plan is important.

On the question, I would like to state that:

* All employees should be performing in accordance to company's strategy

* All managers should provide guidelines and supervision to their departments to ensure the implementation of company's strategy. 

* All managers should report and feedback to senior management about the implementation of strategy.

* Senior management is responsible for monitoring the external environment (competitors, market, clients, government, laws, ..etc) and guide/supervise broadly the internal environment, also to create and review company mission/vision. Based on these inputs, plus required knowledge and experience, senior management will be able to CREATE/UPDATE company's strategy. 

** Many multinational companies require all senior managers to obtain a formal education (like MBA) that ensure that each holds required knowledge of strategic planning among other things, regardless of the company core business or each individual background.

All managers should implement the strategy,by deploying all company resources to achieve and translate these strategies into actions 

some talented managers could create create the strategy

A Strategic Planning or Master Planning is a backbone of Management. You can't simply order your team to perform, you have to give them goals and also define paths to achieve those goals.
