i have done with assignment 1A but i need assignment 1B and i provided you everything about assignment 1A what i have done and what tutor gave me ffedback now you just need to do 1b.

I’m working on a computer science question and need a reference to help me learn.

The request is to refer to strong papers and try to gather information about smart cities development. Then compare some factors in a table.

for example: the application domain (health, learning,…), impact on society (low, medium, high), cost for government, cost for citizen, …… etc.

1. Discuss what ethical leadership is and how it impacts the organizational culture.
2. What are the various dimensions of ethical leadership?
3. Note some failures in ethical leadership, please find an example, explain the failure and note possible solutions to fix the issue with leadership.

Explain the differences in charismatic and transformational leadership and how both leadership styles impact organizational effectiveness.  Please note how these leadership styles affect implementing new innovative technologies.

1. Review table 8.1 in the reading this week, note the work characteristics and the traditional versus high-performance focus, note which focus is best for strategic decisions and which is best for operational decisions.  Please explain.
2. Please be sure to answer all the questions above in the initial post.
3. Please ensure the initial post and two response posts are substantive.  Substantive posts will do at least TWO of the following:

Cyber Security and Risk Management

Be sure to go to the top of the page and look at both data and map.Discuss how risk management comes into play here. (200 words)

Your company is a 4-year-old startup called XYZ Software Enterprises. XYZ produces a point of sale system and was awarded a Proof of Concept (POC) to one of the largest and oldest restaurants in the industry (you know, the ones in the commercials all the time). The restaurant wants XYZ to prove that the software will do what the sales people said it could do.

Your Proof of Concept will include four parts:

Part 1: Gantt Chart.

Part 2: Testing and User Acceptance Report.

Part 3: Use Case Diagram.

Part 4: Activity Diagram.

Part 1: Gantt Chart

A Gantt Chart needs to be created for the entire process of the Proof of Concept. There is a two-month deadline from today to complete the POC. Using Visio or Excel, create a Gantt Chart that includes all of the items listed below and adds five more tasks minimum from the concepts learned from the course:The initial meeting—today. Should appear as the first line. Teams selected to participate in the project (1 week).

Information gathering (add the information gathering methods you will use and how long each will take).

System configurations based on information gathering methods (2 weeks).

Create Activity Chart based on information gathering (information to create chart supplied).

Create Use Case Diagram based on information gathering (information to create chart supplied).

Show the finished configurations to the team and get feedback (1 day).

Make changes based on feedback (3 days).

Install the system in the test store (2 days).

Train staff (1 day).

Run a live test of POC (2 weeks)

Note: The five or more additional tasks can be sub-tasks for information gathering methods as well some other sub-task or major task not in the initial list. You may add items from the SDLC, specific item or items on testing, or any other concept you think should be part of the POC process learned in the course of this semester.

Note: Remember that events in a Gantt chart can happen at the same time as other events. Some items also cannot start until others are completed. Everything has an estimated time frame and it is displayed in the chart.

Part 2: Testing and User Acceptance Report

As part of the expected documentation in the POC, XYZ wants a report on Testing and User Acceptance. Your manager is asking you to research the testing criteria they listed in the POC documents. The POC document states that they are looking for the following:

System and Stress Testing.

User Acceptance Testing (UAT).

For both categories, research and report on the following:

1. What these tests are.

2. Why the industry leader would want these particular tests.

3. The best ways, in detail, to accomplish the tests so that your company meets the criteria they are looking for. These items can be added to your Gantt Chart (Part 1).

Part 3: Use Case Diagram

The restaurant, as part of the information gathering, outlined a use case in a chart, which is below. Your manager assigned you to create the Use Case Diagram using Visio, MS Word, or any other software. (See the diagrams on Page 84 and 85 of the textbook.)

USE CASE	ACTOR
Order Food	Waiter, Patron, Chef
Serve Food	Chef
Cook Food	Chef
Pay for Food	Waiter, Patron
Eat Food	Patron

Part 4: Activity Diagram

As a part of the information gathering process, a chart of items was provided by XYZ. Your manager has asked that you use Visio, MS Word, or any other software with which you are familiar to create the Activity Diagram

PROCESS Activity Diagram Host or Hostess seats patron Server takes drink order Server opens order for table in POS system Server places drink order in the POS system System sends drink order to the Bar Bar makes drinks Server brings drinks to table Server takes food order Server adds food order in the POS system Order goes to kitchen Chef and staff cook the order Food Runner brings food to table Server takes dessert order Server adds dessert order to POS Chef and Staff create desserts Food Runner brings desserts to table Server creates check in POS Server collects payment and enters it in POS Server adds tipped amount to POS Server closes table in

Additionally, you must do the following: Use at least 3 quality resources. Note: Wikipedia and similar websites do not qualify as quality resources. This course requires the use of Strayer Writing Standards. For assistance and information, please refer to the Strayer Writing Standards link in the lefthand menu of your course. The specific course learning outcome associated with this assignment is: Develop a proof of concept of a software system for a potential customer.
