CS 250 Module Two Assignment Guidelines and Rubric
Overview
As the Scrum Master for the Agile team responsible for the product development, you will develop an Agile team charter to help your team be more effective. You will also reflect on a sample Daily Scrum meeting, considering its format and effective practices.
Directions
Before starting this activity, review the Required Resources for this module. You will find additional information specific to this assignment in the Supporting Materials section below.
Use the template provided in the What to Submit section to write a cohesive Agile team charter that briefly describes the SNHU Travel project and suggests some behaviors and communication practices for your team.
Note: Normally, this type of document would have input from the whole Agile team. For the purposes of this class, you will fill this out on your own while reflecting on the perspective and potential input from each role in the Scrum team.
Review this sample Daily Scrum Meeting video. (https://scrumtrainingseries.com/DailyScrumMeeting/index.html) Reflect on the format and effective practices of a Daily Scrum by addressing the following:
What are the key questions that can be used to frame a Daily Scrum meeting? How do they help the team achieve their goals?
How does the Scrum Master help facilitate the Daily Scrum throughout the video? Consider both the Scrum Master’s own updates and times when she responded to team members.
How effective were the actions taken by the Scrum Manager? How could she improve? 
What to Submit
Submit your completed Agile Team Charter Template and a Microsoft Word document containing your reflection on the importance of the Daily Scrum. Your reflection document should be 1 to 2 pages in length. Your work must be your own original effort created specifically for this assignment. Support your work with a minimum of two academic or professional sources published within the last five years (peer-reviewed journals, books, technical reports, government publications, expert industry sites, and so on). All sources used should be cited according to APA style.
Supporting Materials
The following resource supports your work on this assignment:
Presentation: Initial Client Meeting Animation (https://snhu-media.snhu.edu/files/course_repository/undergraduate/cs/cs250/storyline/mod2/story_html5.html)
This presentation describes the Scrum Master’s initial interactions with the Product Owner of the software project for SNHU Travel. 

Find an opensource tool for system or memory analysis. Describe the tool and how it can be used for incident response. Include a link to the tool.

The attached picture is the assignment details and the attached file is where this assignment should be added to. Update the table of contents also.

OVERVIEW
Based on the information you have learned about user interface design so far, interview a person
about a task he/she performs on his/her job. The person can be a parent, spouse, friend, or
colleague—anyone you choose. Your goal is to ask questions that would enable you to design a
system to automate a task he/she performs. Ask this person a minimum of twenty questions that
will help you perform a task analysis.
NOTE: Only questions pertaining to the automation of the task should be included.
This analysis will become part of a requirements document (a document that will guide a
developer in producing the system to automate). Such a document describes the requirements of
the system, which includes an algorithm (i.e., how the task is to be performed), the number of
expected users, the characteristics of the users (i.e., age, expertise, educational level, attitudes
about automation, etc.), the hardware/software needed to accomplish the task, security concerns,
location/setting of the system, connectivity, platform, etc.
Next, observe the user performing the task and identify any gaps or inconsistencies between
what you observed and the descriiption initially given to you in the interview. Were any
differences noted? If so, what do you think accounts for them?
INSTRUCTIONS
In a Word document, provide the following items:
Section 1: List the questions you asked your interviewee and include his/her answers.
Section 2: In a minimum of 150 words, describe what you observed when you witnessed
your interviewee actually performing the task. Note any differences between the
information you gathered in the interview and your direct observation. If differences were
observed, indicate why you believe they occurred.
Section 3: In a minimum of 250 words, describe the task to be automated (task analysis).
Note: At this point, you do not have to describe how your system will automate the task.
You are only gathering information about the task itself at this stage.
Section 4: In a minimum of 100 words, describe your user base (i.e., number of expected
users, age, gender, experience/knowledge about performing the task, etc.).
Note: Your assignment will be checked for originality via the Turnitin plagiarism tool.

Your post must be at least 200 words.
NOTE- 1) APA format
2) NO plagiarism
3)NO AI generated text
4)write reference
5)What ever written in questions i need like same answers No extra NO missing
Your post must be at least 200 words.
Please include:
For the duration of this course, you will be the Chief Data Officer (CDO) of a fictional firm of your choice.
You have a data enterprise that contains structured and unstructured data
As the CDO, you built your company’s first data warehouse or a data lake
