What is the "NeedIt" Application? Why do I actually...need it?

[theseus1817]

I'm studying the "Scripting" section within the ServiceNow > Learn > Training part of the website. The start of these modules has me install something called "NeedIt." I was able to download it and install it. Everything's fine. However, I'm not sure why I had to do this or what the point of "NeedIt" is.

What's the point? What is it's purpose? What is it used for? Why can't I just create a different application and / or scope and create Business Rules (BR) to test and get used to scripting. If the point of learning SN is to understand how SN works, within a SN environment, why use an external demo application to learn how internal SN functionality works? What if there are some aspects of "NeedIt" which don't correspond to how SN actually works? This seems like an added layer of complexity (for training) which is not only unnecessary, but can also cause confusions and misunderstandings about how SN actually works. 

Why not have training which actually works directly within the SN environment?

Hi,

I think the Needit application has been created by ServiceNow guys just for learning purpose, you could use it as a good example, going through the training exercises here:

https://developer.servicenow.com/app.do#!/training/article/app_store_learnv2_buildneedit_jakarta_app...

However, feel free to delete it and create a more "actual" and business-oriented application.

If I have answered your question, please mark my response as correct so that others with the same question in the future can find it quickly and that it gets removed from the Unanswered list.

Thank you

Cheers
Alberto

It is for less experienced users who will follow step by step instructions from Sctipting and other Modules without looking into many details and just focus on specific topics. As Alberto said, you can build your own app and definitely will learn more. In that case those exercises are less valuable.

Good luck.
