Process Modeling

Process Modeling

Project development separated into phases which are composed of steps, which are composed of activities.
The purpose of this process is to make the customers understand better about the system.

1st Group Presentation

1st Group Presentation
25/01/2007
Venue: BW-02-06(COIT)

3rd Lecture meeting

25/01/2007
Venue: Lecture’s office

-we did the interview with our portal project customer that is Mrs.Badariah (SE lecture). This interview is to collect requirements from the customer, because it is very important for requirement analysis.
-bellows are some of the questions that we used:

2nd Lecture meeting

17/01/2007
Venue: Lecture’s office

-In our second meeting with Mrs.Badariah, we discussed on what should be updated in the blog and our lecture explained that the main function of the blog is to act as a report for our se-project, and other than that we are also free to publish anything.
-we also asked our lecture to explain on how to create a planning diagram and how should we present the first blog presentation.

1st Lecture meeting

Venue: Lecture’s office
08/01/2007

-In our first meeting with Mrs.Badariah (our se lecture), we discussed on how to create a blog for example what is our blog host and we also talked about the characteristic of a good blog.

5th Group-meeting

22/1/2007
Venue: COIT

-Confirm the interview date & time with customer (lecture) and we finalize the question for the interview.

4th Group-meeting

17/1/2007
Venue: COIT

-In this meeting, we discuss and design the question needed for our interview with the portal project’s customer (Mrs.Badariah) to collect the requirements of our project.
-in designing the questions, we prepared critical questions like what the portal design is for and what function it requires. But we also design questions about the detail requirements such as, colour of the portal and theme.

3rd Group-meeting

12/1/2007
Venue: COIT

Presentation
-we were required to prepare for the first presentation on portal.
-So we discussed and decided witch part of the blog should be presented, for example why we used www.ink2u.blogspot as our url.
-And then we picked tree presenter to present the blog and every presenter will present different part of the blog.

Process module
-Lecturer, Mrs. Badariah gave each group a transparency OHP paper to draw the tracking progress of the portal project.
-On the OHP paper we need to create the phases, steps and activities regarding the portal development which is part of the planning and managing project.
-Somehow, only few groups manage to present as madam didn't satisfied with the progress requirements.
-So all groups including ours, submit the OHP so that madam may correcting and suggest the new phases, steps or activities.

2nd Group-meeting

22/12/2006
Venue: COIT

-In the second meeting, we validate and submitted the url and group members of our blog to Mrs. Badariah, our software engineering lecture.

1st Group-meeting

20/12/2006
Venue: COIT

-The first group meeting was to discuss about our first assignment in SE, which is to create a blog.
- In our meeting agenda, we discuss about choosing the blog host, the name of the blog, URL, page elements, contents and other additional features.
- As the result, we had chosen blogger.com to be the blog host and www.ink2u.blogspot.com as our url.
- From this task also we start to add blog post and learn something about the blog itself from this assignment.

5 Important Things wee need to do before headin' to madam's class

There are 5 important things we need to do, before headin' to Madam Badariah's class

• make sure you had your breakfast.
• understand all previous chapters
• make sure u brought along some sweets(if possible bring some Karipap so that that u can share with your friends)
• Your notes. (make sure u bring all chapter, In case madam would ask a question which may came from previous chapter)
• Make sure that you are ready to be asked by madam. (Famous word that will come out from madam's mouth, QUESTION???)
  

Waterfall Model

-Works for well understood problems with minimal/ no changes in the requirements.

-Simple and easy to explain to customers.

- It presents a very high-level view of the development process.

-Each major phase is marked by milestones

Ariane 5 Inquiry Board Report

Some excerpt from the report for Ariane 5 failure;

3.2 CAUSE OF THE FAILURE
The failure of the Ariane 501 was caused by the complete loss of guidance and attitude information 37 seconds after start of the main engine ignition sequence (30 seconds after lift- off). This loss of information was due to specification and design errors in the software of the inertial reference system.
The extensive reviews and tests carried out during the Ariane 5 Development Programme did not include adequate analysis and testing of the inertial reference system or of the complete flight control system, which could have detected the potential failure.

In details the full report by the Inquiry Board;

Ariane 5 Flight 501 Failure

Flight 501, which took place on June 4, 1996, was the first test flight of the Ariane 5 expendable launch system. It was not successful. Due to a malfunction in the control software the rocket veered off its flight path 37 seconds after launch. It was torn apart by high aerodynamic forces which caused the onboard computer to trigger self-destruction.
The breakup caused the loss of the payload: four Cluster mission spacecraft, resulting in a loss of more than $ 370 million.
It is one of the most famous computer bugs in history.

The Ariane 5 software reused the specifications from the Ariane 4, but the Ariane 5's flight path was considerably different and beyond the range for which the reused code had been designed. Specifically, the Ariane 5's greater acceleration caused the back-up and primary inertial guidance computers to crash, after which the launcher's nozzles were directed by spurious data. Pre-flight tests had never been performed on the re-alignment code under simulated Ariane 5 flight conditions, so the error was not discovered before launch.

'WoW' Windows Vista

Windows Vista, Microsoft's latest OS was officially launch in KL Convention Centre for preview to the business and corporate leaders yesterday (which is Saturday Feb 3) and for public release and viewing in Low Yat Plaza starting today. (Let's go!)

Windows Vista, along side with Microsoft Office 2007 and Exchange Server 2007 promises a core platform which enables business to reap the benefits of Internet-based software that offer balance of control, convenience, increase productivity and of course greater security and entertainment.

Windows Vista ships in six editions. All editions except Windows Vista Starter support both x32 and x64 processor.

Now, it makes our XP looks obsolete. ^^..
