If this is an area that you would like to get in to then it is a really good idea to get on a training course and learn this software.
If you are used to using Microsoft™ products then you will find the basics quite simple but it is a good idea to do a course and find out all about all aspects of it and then you will have the full set of skills required.
It is a very useful software package because it will help you to draw out project plans. This means that you can put in each section of the project and a time scale for each. You can then update it when you start the project as nothing ever goes exactly to schedule and you will be able to amend it as necessary.
Most projects use some sort of planning software like this and so even if you are hunting for a job and not sure what software you will be using, it is a good idea to get trained up in it.
It will still show that you have an ability to use this type of software and most places still use Microsoft™ anyway and so it is likely that it will be the package that you will be using.
Even if you are not actually in the project managers role it could still help the team if you know how to use the software and amend the project plan.
The course could be expensive and if you do not have an employer to pay for it then you may find it difficult to afford but think of it as an investment, especially if you need these skills to secure yourself a job.
