Project Progress Summary

Main wiki page

Mid-term wiki page

Project Highlights:

Changes in Application

  • Synchronous to Asynchronous

This is a major change occurred in system architecture after midterm stage. When the application was first designed, the components and functions of the application had been set to work synchronously with each other due to the interdependence of the outcomes between them. This system design caused a lot of issues on the performance and usability of the application. So we decided to change it to work asynchronously without waiting for the results of other components. A lot of logical changes have been done and when the components are able to work asynchronously, there is a massive boost in performance as we expected.

Changes in Scope

  • Function Dropping

We dropped the function "Friend Stream" which we assigned as optional feature in our proposal. The reason is mainly due to the existence of serious performance issue in the application. The application's failure to run seamlessly during midterm period caused a setback in team progress. So we decided to drop the non-compulsory function "Friend Stream" to focus more on the quality attributes such as performance, reliability, etc.


Project Achievements:

  • Schedule

When we were scheduling our project, we tried to plan it in such a way that the coding of functional requirements could be finished as early as prior to midterm presentation. We pushed all the bug-fix and performance-tuning tasks of each function to the iterations in post-midterm period. This approach clearly helps us in preventing our team from using "Waterfall Process" involuntarily in which we might never re-visit or revise it again when we finished a feature. The agile methodology we used not only forces us to go over to the features we previously developed for bug-fixing and backward compatibility checking but also gives the stakeholders (sponsor and users) an overview idea of how each of the features works and interrelations between them.

  • Metric

We also used a metric called "Workload Value Point" among team members. We assigned each task a value point based on the difficulty and time consumption of the task at the beginning of an iteration and those value points were given to the persons who worked on the tasks. This metric reminded every team member if he/she shared equal workload and kept the pace as other team members. Every team member had a chance to make up the amount of effort he/she lacked in one iteration due to several possible reasons in another iteration by looking at the numbers of this metric. It is especially useful for projects done by students like us because everyone has different time schedules and not everyone can commit all of his/her effort on one project all the time.

Project Management

Provide more details about the status, schedule and the scope of the project. Describe the complexity of the project.

Project Schedule (Plan Vs Actual):

Compare the project plan during midterm with the actual work done at this point. Briefly describe a summary here. Everything went as plan, everything has changed and the team is working on a new project with new sponsors or the supervisor is missing. A good source for this section comes from the project weekly report.

Provide a comparison of the plan and actual schedule. Has the project scope expanded or reduced? You can use the table below or your own gantt charts.

Iterations Planned Actual Comments
1 Customer CRUD 1 Sept 2010 25 Aug 2010 Fiona took the Sales CRUD as well.
Trend Analytic 1 Sept 2010 15 Sept 2010 Ben is too busy and pushed iteration 1 back
2 User tutorial 1 Oct 2010 Removed proposed by Ben
Psycho analysis 1 Oct 2010 New module proposed by sponsor

Project Metrics:

Summary of analysis for the metrics collected. You may refer to another page for the details about the metrics and how it is collected.

Technical Complexity:

Describe and list the technical complexity of your project in order of highest complexity first. For example, deploying on iPhone using Objective-C, customizing Drupal with own database, quick search for shortest flight path, database structure, etc.

Quality of product

Project Deliverables:

List the artifacts produced for this project. The entire deliverable can be submitted in a separate thumb drive, web repository or place in the IS480 team wiki.

Deployment Diagram instructions

Not all parts of the deliverables are necessary but the evidence should be convincing of the scope.

Quality:

Explain the quality attributes (non functional) of your project deliverable. Have you designed the architecture, use a design pattern, etc? Does your architecture address scalability, performance, reliability, availability, fault tolerance, usability, etc. Does your design address maintainability, flexibility, configuration, etc. Be brief here but you can link to diagrams or code detail pages. Do not repeat the technical complexity part, link to it if necessary.

Performance and Scalability

Although it is a web application, 3DSocializer does most of its functions at client side using client side scripting technology such as Javascript. So the major part of application will not burden much on the server resource which adds scalability in terms of server resources. However, it has a limited scalability on the number of tweets that it can handle in a period of time. The issue is identifiable when a large amount of tweet feeds are returned from twitter in a very short period of time, the application in user's browser will have some slow responses. This scalability issue is mainly due to processing in some resource intensive components such as 3D which is not easily solvable by the team.

Configurability

Some of the configurable parameters of the application are defined in an XML formatted config file.

Maintainability

A code organization guide is documented for easier maintainability of the source codes in the future.

Deployment:

Application has been deployed at 3DSocializer

Testing:

Describe the testing done on your system. For example, the number of UAT, tester profile, test cases, survey results, issue tracker, bug reports, etc.

Reflection

Compile common lessons and reflection for the team and for each team member. Be brief.

Team Reflection:

Key lessons learned – indicating where the team improved, or would do things differently next time. You may refer to the learning outcome summary in your proposal. A very short checklist style will suffice. It would be very convincing if the knowledge is share at the wiki knowledge base and linked here.

Individual Reflection:

Describe in a paragraph, the key areas of learning or improvement. These should be personal areas of growth or learning. Each individual should list his/her effort, responsibility, actual contributions and personal reflection. Do not repeat team project contributions or member roles. Link if necessary.

Sometimes, the client writes a report to feedback on the system; this sponsor report can be included or linked from here.
