The short answer to your question: Yes. You can use "to" instead of "in order to." But the expression "in order to" is more specific. The word "to" has many different uses. Consider how 方（ほう） can mean direction (空間方向) as well as method (方法) . . . "To" can mean へ、に、方、ために, etc. (direction, purpose, etc.) "In order to" is more specific and only means ために (for the purpose of . . .) I hope this helps. I hope I didn't make it more complicated. （笑！）

Yes, 'in order to achieve" and "to achieve" are both fine. 'in order to' means 'with the aim of' or 'with the objective of" "Team management is the ability to organize and coordinate a group of individuals with the objective of achieving a desired outcome, goal or task." You can simplify and just say 'to achieve', and the meaning is similar, BUT not quite the same. With your version there is less stress on intention or goal or aim because you are omitting the 'in order..' You are still saying you will achieve, but you are not saying there is a goal/aim to achieve. There's a difference.

“To” is used with the base form to form the infinitive — it can be used in many contexts: Like to, want to, have to, be going to, etc. “In order to” has a specific meaning: For the purpose of (doing something). It is common to leave out the “in order”, simply using “to”. There’s nothing wrong with it, but your meaning will have to be understood in context. If you know there’s enough context that the reader can figure it out without undue effort, then fine. If you’d like to be clearer, then you can use the full phrase “in order to”.

Thank you, Andrew. I appreciate your answer.

Generally "in order to" and "to" can be used interchangeably. In your example above, this is the case - using either "in order to" or "to" are both fine and mean the same thing. Occasionally there are cases where "to" could be ambiguous, and "in order to" would clarify the meaning. For example "I need Bill to beat the video game." could mean "I need Bill himself to beat the video game" or "I need Bill with me so that I myself am able to beat the video game." If you use "I need Bill in order to beat the video game", then it's clear that the meaning is the latter.
