How can you distinguish between the right decision and the bad decision?

You will definitely realize the bad discussion once you fail to achieve  the goals set (failer)   

Right decisions are the ones taken within the overall policy framework and facilitating continuance of operations to bring targeted resultts.

The secrect of Bad decisions, if taken by Management, should onle be known to the Management and there may not be logical reasons to upheld such decisions.  

To distinguish right and bad decisions is to foresee first the probable results. It is still better to ask those expert people then weight it to which is which is more efficient and effective.

Thanks for asking , as far as I am concerned , the only way to verify the pertinence of a decision is its results but it is possible to ask for advices or opinions of others in order to clarify our idea 

From experience it is always important to try and ask for advice and peoples opinions. Listen to suggestions but as a person you would be able to distinguish the right and wrong.

Example: I am going to buy that BMW next month but can't really afford it because i have a nice car already but still want to be in the picture and my family situation just need to adapted to the new BMW instalment. What do you think ?

Example: Ask yourself if you would be in a situation when you are asked a question from someone in your department and he wants to use tools or need to move a heavy table in the department and you know it can't be done now what would you say Right sounds great or would you say Bad decision for the fact of  improper planning and time.  

Thanks for invitation,

Simply via "feedback" process, for example, if the decision is mainly aiming to solve a problem, I have to collect feedback to be ensure that the problem is completely solved, consequently it is consider a right decision, otherwise it is consider a bad decision and has to be reviewed once more to reach the right one.

Would vote for  Celeste Ann Mascarenhas answer.

a right decision  is decision made and regrate in the end,a bad decision is a decision with regrate in the end. but befor someone makes a decision must think tiwce. 

Thank you for the invitation.

People who never choose because they're afraid of making the wrong choice miss out. Period. There is no such thing as a wrong decision. People who look like they've made the right decision are simply masters at making the most of the decisions they make. Step up to the plate. Get on with your life.

Though there's no sure-fire way to never make a mistake, paying attention to signs we're en route to bad decisions can help us switch course before it's too late. Be prepared to step ... “It takes practice to break the habit of responding right away, but it really is just a habit,” Ryan says. Break it by requesting change.

Making the right decisions brings the best outcome to the problems and a wrong one will not achieve getting the best solution to a problem it will not eliminate it on the contrary it will re-appear after a while and with a worst problem.

Apply these eight rules when weighing your options to ensure that your decisions always play out in your favour or best outcomes:

Pay attention to signs. The first rule asks us to open up to obvious signs. The universe tries to offer guiding signals that we often miss or neglect if we’re not tuned in. Anything can be a sign.

Keep clean your conscience. No decision should stain your spirit. Do your best to act for the good of everyone, not just for your own good. Decisions that hurt others and only benefit you will eventually turn against you. When in doubt, consult your moral code. Keep your conscience clean by making clean choices.

Detach from negative emotions. Nothing keeps us stagnant like our own fear, impatience, and frustration. Moving forward with the right choices means we must eliminate these emotions. If we weren’t afraid of anything, we would act with incredible courage. If we weren’t so impatient, we would wait until the right opportunities rolled around. And if we didn’t become so easily frustrated, we would extend our perception. Understand that these feelings are impediments to the progress of your life and that when you eradicate them, your decisions no longer stem from your ego but from your highest self. Always remember this rule of thumb: never make a decision under desperation.

Know your influences. We often turn to our friends for guidance when we’re confused. Why do we do this, when the right answers are all within us? When we recognize who influences us, we can discern whether their advice is causing positive or negative effects.

Follow your intuition. In the words of Swiss writer Johann Kaspar Lavater, “Intuition is the clear conception of the whole at once.” Our intuition puts into perspective the entirety of a situation: it takes us beyond one moment in time and reveals how things will unfold in the future. The truth is that we already know exactly what we must do and what will happen, if only we follow our internal GPS. Intuition is what feels right inside, and it isn’t just some “gut feeling;” our instincts can reshape our lives. Following our intuition helps us realize that we have the power to make the right decisions.

Don’t cross red flags. Just as much as the universe offers signs, it also puts up red flags. For example, if unexplained “coincidences” are stopping you from doing something, reconsider your decision.

Organize your thoughts Positive thoughts turn on the “possibility” switch: when we think something good can happen, we take the right actions to ensure it comes true.

Put into words the entirety of your thoughts—the good, the bad, and the ugly. Then, jot down your choices and their potential outcomes. Project what would happen if you did one thing versus if you did another. Circle the choice that you believe will lead to your highest good. Organized thoughts lead to wise decisions.

The pressure of making the right decisions can be overwhelming, but acting on these principles, our choices become infallible and our lives more rewarding.

Simple, decision making depend on situation, time, contents etc, if it prove well and in line with yours target objectives (short term and long term) then it is good decision otherwise bed decision, interestingly, when you take decision at the same time must carried out the CBA of the project, of the business.

Thanks
