In short:
It’s easy to share to a wider community.
It works well on mobile and adapts to any screen size unlike documents and presentations.
It’s fancier than a deck and you can make it more interactive.
It’s the start of a communication plan as you're building an information hub that you can re-use in the future
It’s easy to share
The beauty of a website is that you have just a link and everyone can access it easily. No need to think: do people have access or not? Do people need an account to view the document?
For workshops where the results can be shared to a wider community a website makes it very easy to touch anybody.
It works well on mobile
Most documents are made for desktop. A word document doesn’t look great on a smartphone, a slide deck can be viewed on mobile but you’re forcing people to turn their phone to view the content.
With a website people can simply scroll as they are used to and the content adapts to the size of their device. It looks great on mobile, tablet and desktop.
This is especially important when you share the workshops results with a wide community. The wider the community is the more chance there is that people will check the content through there smartphone.
It’s fancier than a deck
Having a little « wow » moment after the workshop is a welcome touch. When people expect to get a word or PowerPoint document and you send them a full website it’s definitely surprising.
Depending on the project you might want to finish with a wow effect and a website helps for that.
It’s the start of a communication plan
Some workshops have a huge impact on an organization and therefore are the start of a wider communication campaign. For example when a workshop sets a new strategy for an organization, you know that this strategy will have to be communicated with a wider community and that a full communication plan and campaign will come after the workshop.
By having a workshop report that is a website you are helping kickstart that communication plan by giving something that is pretty easy to share and that you can share fast while in parallel people work on the long term communication plan.
You can communicate right after the workshop about the workshop results with a wide community without having to wait weeks or months for all the communication plan to be finalized.
