Ready to get started? Task 1 is waiting for you!

TASKS AND ASSIGNMENTSAs you know, our consulting firm has been selected by the

client, the College’s HR Department, to design and implement a rewards program that will reward college employees with

cash reward for being is good physical shape.

Please complete all the steps to the tasks, and refer back to your Working in Teams and Working with Tasks overviews if

you run into any obstacles.

TASK 1: RESEARCH AND ANALYSIS

For this task, you will determine the list of items on which the employees will be rewarded

and the value of those rewards.

OverviewYour first task is to develop and deliver a list of items on which employees will be rewarded and the amount of reward for each item. You must do this by suggesting ideas as a consulting team. More specifically, discuss the items which you know can be used to determine how physically fit an employee is, what you don’t know, what you need to know, and how to fill the gaps and then organizing those ideas into a brainstorm document.

Overview (cont.)The categorized brainstorm must be submitted to the client within the client’s timeline and delivery method, for their review and approval.

Deliverables1. A brainstorm document listing the items

that will be used to evaluate and reward the fitness level to the client for potential further research and exploration to address the client’s needs. All the ideas from the brainstorming session must be logically placed in general categories that can be easily understood by the client.

2. Definition of roles and tasks assigned to each team member and a work schedule

Action Plan1. You must begin by brainstorming

everything you currently know about being physical fit. Consider all creative ideas and be as exhaustive as possible and non-judgmental.

Action Plan (cont.)2. Next, move to all items you might not

know or understand about physical fitness that may be relevant to this task. Again, consider all ideas as valid and reserve judgment. Definition of roles and tasks assigned to each team member and a work schedule.

Action Plan (cont.)3. Then, begin to identify the gaps

between what you know and what you don’t know. The client asks you to be thorough. Be sure to consider what else you might have missed.

4. Take a look at the results and notice the repetition of words or ideas. Begin to sort and group logically these ideas into a few descriptive but broad categories

DebriefReflect on what we've learned from this task by discussing the following questions with your colleagues and manager(s):1. Did you find and learn medical

vocabulary related to physical fitness that you were not familiar with?

2. Was your research thorough and uncovered details?

Debrief (cont.)3. Is your proposal addressing the

needs of the user?

4. How did your team reach consensus on their job roles?

5. Did you develop a schedule that would meet the client request?

Debrief (cont.)Also reflect on what we've learned from this task by discussing the following questions with your manager and team:

1. How successful was your team at following the work plan you created for this task? What have you learned about each other as teammates? How can you use each other’s strengths to work more effectively in the next tasks?

Debrief (cont.)2. Do you feel like the team’s plan for

uncovering details was efficient and well thought? Do you feel like you contributed too much, too little, just enough? Did you learn something new about the process of discovering threats in a computing environment?

Debrief (cont.)3. How did the team prioritize the

needs and resources differently? How did they justify their choice? Do you agree with them? Did you feel the team worked like a real-world team would? How you re-prioritize the needs based on their presentations?

Your team is doing well. It’s time for your next task.

TASK 2: GUI DESIGN

For this task, you will design the user interface for the application to be developed.

OverviewYou are working together great so far. Your completed research proposal has been reviewed by the client and they satisfied with the proposed list of categories and the reward associated with each category.

The next step is to design GUI for the application to be developed using established GUI design practices. The developed GUI will be presented to the client for feedback. The feedback then would be used refine and polish the final GUI.

GUI Principles*The structure principle. Your design should organize the user interface purposefully, in meaningful and useful ways based on clear, consistent models that are apparent and recognizable to users, putting related things together and separating unrelated things, differentiating dissimilar things and making similar things resemble one another. The structure principle is concerned with your overall user interface architecture.

*Constantine L., and Lockwood, L. Software for Use: A Practical Guide to the Essential Models and Methods of Usage-Centered Design. Reading, MA: Addison-Wesley, 1999.

GUI Principles (cont.)The simplicity principle. Your design should make simple, common tasks simple to do, communicating clearly and simply in the user’s own language, and providing good shortcuts that are meaningfully related to longer procedures.

The visibility principle. Your design should keep all needed options and materials for a given task visible without distracting the user with extraneous or redundant information. Good designs don’t overwhelm users with too many alternatives or confuse them with unneeded information.

GUI Principles (cont.)The feedback principle. Your design should keep users informed of actions or interpretations, changes of state or condition, and errors or exceptions that are relevant and of interest to the user through clear, concise, and unambiguous language familiar to users.

GUI Principles (cont.)The tolerance principle. Your design should be flexible and tolerant, reducing the cost of mistakes and misuse by allowing undoing and redoing, while also preventing errors wherever possible by tolerating varied inputs and sequences and by interpreting all reasonable actions reasonable.

The reuse principle. Your design should reuse internal and external components and behaviors, maintaining consistency with purpose rather than merely arbitrary consistency, thus reducing the need for users to rethink and remember.

Deliverables1. A preliminary GUI design which should follow

the GUI Principles

2. A survey for client feedback

3. A refined GUI based on client feedback

Deliverables1. A preliminary GUI design which should follow

the GUI Principles

2. A survey for client feedback

3. A refined GUI based on client feedback

See document “Task 2 Resources” for reference.

Debrief1. Does your questionnaire include enough

thorough questions that you would need to ask your client in order to refine your GUI design?

2. Did client request major revisions to your GUI design?

3. Is the client satisfied with your revised GUI design?

Nice job! You’re set to move on to the

next task.

TASK 3: CODING

For this task, you will provide the functionality behind the user interface design.

OverviewThe client is exceedingly happy with your revised GUI design and has approved the GUI. Excellent job! We are now ready for the next stage of our project, providing the functionality behind the design GUI. The code should follow clean coding practices. See Resources for a guide to clean coding practices.

It may also be beneficial to revisit Working with Tasks and Working in Teams before you start developing the application.

Deliverables1. Implement and integrate all aspects of the

deliverables of Task 1.0 with the developed GUI.

2. Develop a user manual for the application.

Action Plan1. Ensure all aspects of the application are

working properly.

2. Write the application user manual.

3. Make sure that you have a back up of all your work.

Debrief1. What elements of other teams’ solutions

did you particularly admire? Why?

2. Do you have a better understanding of software development process?

3. Do you have a better understanding of how to write clean code?

Good work developing. You’re ready to move on!

TASK 4: TESTING

For this task, you will test the application you’ve built before sending to the client.

Deliverables1. Create a document that details plan to

test the application for correctness and accuracy. Define testing strategies for each area and sub-area to include all the functional and quality (non-functional) requirements.

2. Divide deliverable of Task 1.0 into testable areas and sub-areas. Be sure to also identify and include areas that are not tested.

Deliverables1. Define bug-tracking procedures.

2. Identify testing risks.

3. Provide testing schedule.
