Create a report for your Manager on Information-Gathering Techniques.

Gathering information for a new system is important and sets the tone of the development cycle. If not done thoroughly, the project could be a failure before it begins.

You are the Project Manager of XYZ Enterprises. Your manager gives you the task of researching the different techniques used to gather information as the company is going to replace their Case Management System. He would like a report of all the different type of information gathering listed below. For each technique, give reasons to use it and the best ways to accomplish using each information-gathering method.

Interviewing users and stakeholders. Distributing and collecting questionnaires. Observing and documenting business procedures. Collecting active user comments and suggestions. Researching vendor solutions.

This course requires the use of Strayer Writing Standards. For assistance and information, please refer to the Strayer Writing Standards link in the left- hand menu of your course.

w06a1 - Human Computer Interface (HCI)

Summary

Click the linked activity title to access this assignment.

Text

Everything we touch that is electronic has a Human to Computer Interface (HCI). Some companies put a lot of effort into the user experience; some, not so much. Some are very complex with enormous functionality (computer operating systems and smartphones) and some are much simpler (ATMs, gas station pumps, lottery ticket machines, movie dispensing machines).

For this assignment, choose either a simple interface (one with a few options) or a singular function of a more complex item (like a singular function of your smartphone, such as to create and send an email). Remember that there are several options for many of these. Visit the interface that you chose.

Note: Keep your selection to something simple, as you will find there are many options even in a simple task.

Write a paper in which you address the following:

1. Research history and background of the HCI (just a few of paragraphs). 2. From your chosen HCI, describe all the steps and options that are available to use and complete the task. 3. Build an Activity Diagram such as those on pages 138 Figure 5-5 and 139 Figure 5-6 of the textbook. Use Visio, MS Word, or your choice of program

that can create an activity diagram. You need to create the diagram, not take one from the internet. 4. Reflect on the experience. Do you feel the process you chose was well designed? Do you think it can be improved? 5. Use at least two 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 left- hand menu of your course.

Include charts or diagrams created in Visio, Word, or an open source alternative to create the diagram. The completed diagrams or charts must be imported into the Word document before the paper is submitted.

The specific course learning outcome associated with this assignment is:

Evaluate the efficacy of the design of a human computer interface.

Considering that enterprise system implementations fail 40 percent of the time, there is substantial risk involved—risk that, in many cases, can put a company out of business.

Research project risk and feasibility. For each of the following risk categories, discuss:

1. What the type of risk is. 2. Ways to help mitigate the risk category.

Examine your current place of work, or an organization of your choice, and write a paper in which you discuss:

Organizational Risks. Technical Risks. Resource Risks. Schedule Risks. Use at least three quality resources. Note: Wikipedia and similar websites do not qualify as quality resources.

w10a1 - Technical Paper: Proof of Concept (POC)

Summary

Click the linked activity title to access this assignment.

Text

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 (see page 353, Figure 11-18 in your textbook) 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.)

Paste the diagram into the created report.

USE CASE ACTOR

Order Food Waiter, Patron, Chef

Serve Food Waiter 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 (see pages 138 Figure 5-5 and 139 Figure 5-6 in the textbook.)

Paste the diagram into the created report.
