Tasks and assignments

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

TASKS AND ASSIGNMENTS

Your Live Website developed Hillside Restaurant’s website. In the next month your team will be organizing itself, fixing bugs, changing content, and adding features to the site.

This project consists of four tasks: organizing a team, installing a development environment, software maintenance and implementing new use cases.


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Project Overview

  • At Your Live Website, teams are highly collaborative so that all of the developers know how all of the code works. To this end, tasks are assigned to pairs of developers and all code written by one developer is always reviewed by at least one other developer on the team.

  • In order for your team to function effectively, first you must agree on some ground rules and make a schedule. This will take up your first week on the job.


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Project Overview

  • All web developers must use a set of tools that will aid in their work. So your second week will consist of choosing and installing these tools and learning how to use them effectively.

  • After you have demonstrated that your chosen toolset works properly on your development machine, you will be assigned a set of bugs to fix in the website for Hillside Restaurant. Finally, you will add two new features to this website.


Task 1 organize your team

HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

TASK 1: Organize your Team

For this task, you organize your team, define roles and work on team dynamics.


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Overview

  • Before you begin, you first have to organize your team and agree on a plan for success. Experience has shown that if you know the details of the product you are developing, and if you get your team functioning properly at the beginning, then you will be on schedule during the whole project. This first week is also critical in order for your team to learn about and take advantage of the skills of each team member, which is required for a team's success.


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Overview

  • Teams only work if everyone does their part. You’ll collaboratively write a contract for your team to decide on how you will work together to deliver the project. Much of your bonus will depend on how you - as an individual - meet this contract, or deliver on your commitments, during this project.


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Overview

  • How is your team going to meet each of the deadlines and submit quality work over the next few weeks? Everyone needs to know what is expected of them and especially when. It is up to the team to decide what schedule will include time for early submittal for the team's review. BEFORE your team submits any work to your director, the work must be reviewed, critiqued and edited by team members.


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Overview

  • Your team's first step is to define key roles, decide who will fill them, and agree on rules of communication, logistics and your project schedule. I’ve detailed requirements to lead your through this process.

  • Keep in mind that at the end of the project, your team will be eligible for a bonus. If your team receives the bonus, you will be asked as an individual to advise me on how to divide the bonus among the team members.


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Deliverables

  • Team Contract, signed by each team member.

  • Team Schedule; your project manager will give you a template. Fill in all but the starred fields. Define roles and tasks assigned to each team member and prepare a work schedule.


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Action Plan

  • Hold a team planning meeting with the following agenda:

  • Analyze your team members' skills

  • Define and assign roles (e.g. manager, time keeper, recorder, presenter, contributor, researcher.)

  • Create the first draft of the team schedule using the template provided.


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Action Plan

  • Hold a team planning meeting with the following agenda:

  • Be aware that to receive full credit, you must use all of your team's resources in all of the deliverables.

  • Think of things that might go wrong and agree on what the team will do to recover.

  • Find a convenient time and location for team meetings.


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Action Plan

  • Write a team contract, and have each team member commit to it by signing it (this can be done by typing your name at the bottom indicating agreement if working online.) This contract delineates good team member behavior with regard to things like attendance at meetings, response to requests, meeting of deadlines, and review of other team members' work.


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Tips for Success:

  • In all team meetings, enforce a 2 minute rule where nobody can talk for more then 2 minutes at a time. Begin by brainstorming everything you currently know about making a hotel reservation. Consider all creative ideas and be as exhaustive and non-judgmental

    • as possible.

  • Move to all items you might not know or understand about website maintenance that may be relevant to this task. Again, consider all ideas as valid and reserve judgment.


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Debrief

  • Did someone on your team race ahead and start working on the project itself without the rest of the team? If so, how did that make the rest of the team feel?

  • What might prevent a team member from attending a future meeting that is currently on the schedule? What can the team do to avoid that happening?


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP

  • Debrief (cont.)

  • How much time does your schedule allow to incorporate feedback from team members into your deliverable before you submit it to your director?

  • What will your team do if one of its team members drops out?

  • How did you enforce the 2 minute rule? Why? Was it worth the effort?


HOME | OBJECTIVES | WELCOME | TASK 1 | TASK 2 | TASK 3 | TASK 4 | HELP
