Before using data you must make sure it is valid. This is because it is the most fundamental characteristic of data. When you collect data you must make sure it is correct before it is used. To make sure it is correct look at multiple sources (where necessary and if possible) and then you should double check it.
Making sure that information is reliable is the best thing possible. As you wouldn't want to find out that the information you had used was inaccurate. You should use data from a valid source that you can trust. Don't use Wikipedia as information can be changed by anyone there. If you are collecting the data yourself you should check it against someone else's to see if you have similar results. Also always check that data is up to date.
Timely information just means information that was prepared and ready for when it was needed to be used. This could mean an assignment that had to be handed in on a specific date. If you work in a business that requires you to research or find out about data your managers will hold regular meetings to see how you're doing and to see if it is relevant.
Fit For Purpose
When you gather information you need to make sure that it is fit for the task you need it for. It needs to be easily understood by the target audience, it needs to provide answers to the questions asked, it also needs to be descriptive.
It would be pointless to gather research and make a database or a presentation and then make it so other people can't access it . You need to make sure you and everyone else can access it. Especially when you're working in an organisation or a big project.
When collecting primary data the costs can be quite high compared to secondary data collecting. It's probably always best to use secondary data as long as you know it is reliable. Although there will be some circumstances when you will need to collect data yourself.
