Knowledge Base - setting up within O365/Sharepoint

Hi Yeow,

One of the third party products i have used in the past is Knowledge Base from Bamboo which is pretty impressive but i think the pricing is a bit on the high end side. 

Anyways, for OOTB Wiki you get three options and its up to you which one to choose from. 

- Site Pages Document Library: For me personally this is the easiest and best way to get started because  you already have a Wiki library on your SharePoint site. If you click on Site Contents and look at Site Pages – you will notice that its a Wiki Library mentioned in the TYPE Column. Now Click on Site Pages and the Home page will come up which is the Homepage of your SharePoint site. Whenever you add or create other pages on your SharePoint site, they all end up in this Site Pages Library. This actually means that can add Wiki or Knowledge Base pages/articles right inside the Site Pages Wiki Library, without creating an extra one. The only difference between Site Pages Library and Wiki Library is that you won’t get Updated Pages section with the Site Pages which is a unique feature of Wiki Library mentioned below as the 2nd option. 

- Wiki Library Web Part: For this option click on Site Contents > Add an App > Wiki Library. Once created, you will see two default pages which appear OOTB and you can create new ones. You will also notice how similar it is from the first option i mentioned above. Try creating some New Pages and add in some stuff like text, pics, vidz, etc and you will notice that the Updated Pages section in the upper left-hand corner shows you the recently updated pages.

- Enterprise Wiki: Now this one is a template which you choose when you create a new site and in a way, you will actually be creating a separate site (subsite) specifically for your Wiki. Please do remember that this Site Template is only available on site collections with publishing features enabled and my two cents would be to play with it before going ahead with the Publishing feature. 

All three options have pros and cons so it all boils down to what exactly do you plan to achieve. Again, i believe that its always a good idea to start small and then slowly build up as Users come with ideas and suggestions. Even if you don't intend to go ahead with OOTB features - at least you will get to know what your Users are expecting and they feel comfortable with. It would be a good approach to see the 3rd party products with your scope / requirements in mind.
