BRD, Requirements Document in Agile Scrum?

While comprehensive documentation is valuable, a working software is MORE valuable as per the Agile Manifesto. One of the myth about Agile Scrum is that it promotes no documentation. The fact is that documentation is certainly not a bad thing, but Agile suggests to create minimum required documentation.

So the question is where do you keep user requirements - trying to find something similar to BRD (Business Requirements Document) in Agile?

The answer is rather simple - "product backlog"! Product backlog is only place to capture all the user requirements and as we know these requirements are prioritized by product owner for each release, sprint and is called release backlog and sprint backlog respectively.

Impediment v/s Bug - are they same or different?

Let's understand what is impediment and bug in Agile Scrum. First of all they both are not same, they may be distantly related in some special situations but they are different.

Here are the basic definitions:
An impediment is a situation that is stopping/blocking the completion of work.
A bug is referred to a defect or issue in the work product.
On side notes do you know that the word "bug" was used to indicate an actual bug (fly, moth) on a circuit board causing a short-circuit or other problems. You can read more details here - http://theinstitute.ieee.org/technology-focus/technology-history/did-you-know-edison-coined-the-term-bug

A defect would typically NOT block the completion of work, though in some situations a defect may impede work and also be am impediment at same time. For same reason, a defect would relate to implementation of a work item (user story), where as impediment would block one or more work items (user stories).

Defect and impediments are tracked seperately in defect tracker and impediment tracker. Bugs would eventually be prioritized and added to product backlog and re-prioritized by product owner. Impediments would never be added to product backlog, but resolution of an impediment may be taken out as spike; if some research work is involved and/or a major bloker to work.

While bugs can be identified during development activities (coding, testing etc), and impediment would typically be identified during daily scrums. The scrum master is responsible for helping resolve these impediments to improve team productivity.
