Who should be in charge of designing the database – team members, who understand the application requirements, or a database design expert, who may not understand the problem domain issues but does understand good database design?

I believe the database expert would be the best choose for designing the database, so they should be in charge. T…[Read more]

Hi Linlan,

I too agree with you comments about separating the different roles. Segregation of duty is always a great way to protect the integrity of a function. As stated by Xiaomin (above) the differences in roles with regards to a database designer, administrator, developer. each of these roles are defined by their duties (explained above)…[Read more]

Binju,

I truly agree with your comment about understanding what kind of protection is needed based on the sensitivity. It is important and would prove to be more efficient to separate the data out into levels of sensitivity and identifying the data that actually needs encryption opposed to possible encrypting something that isn’t necessary.

HI Karabo,

I agree with your CRUD statement. The CRUD matrix is driven by the use case diagram which assist in identifying and driving the user’s authorization.

What does it mean to have integrated models?

An integrated model is the assessment of several models which combines their activity into a single agenda opposed to measuring each model separately. Thereby identifying inconsistencies, and controlling the accuracy of the information.

HI Hanqing,

I agree. Cross checking will not only reduce the time and cost but will also ensure that the project is successfully completed and meet all requirements.

HI Xinteng,

Great post. Also, when cross checking in not completed it could cause the project to fail because of the continued errors that may occur and the time/money needed to resolve them. If cross checking is preformed it will assist in eliminating these issues.

How can cross checking between models ensure that the requirements are accurate and correct?

Cross checking ensure consistency and completeness between the diagrams, which will result in a quality product. Cross checking between models guarantees that the stated requirements are correct and the information is valid in different diagrams.…[Read more]

Yes, everyone’s diagram will differ because of the difference in interpretation of the reading, as well as some provided details could have been overlooked. However, there should be certain key factors that will not differ too much. The data model reflects the business rule which drives the nature of the organization and the rule outlines the…[Read more]

Hi Arron,

Excellent point. I would think that if a project had a financial asset tied to it that getting it right the first time would be at the top of the list. The risk of data not being analyzed first is too great and could be very costly. I couldn’t imagine completing a project without first analyzing the process in its entirety.

I truly can not think of any scenario where formal data analysis is not needed. However, I am certain that there are cases out there where data analysis was not completed because someone believed that it was not needed. Needless to say, I’m sure the implementation process must have been awful. Data analysis assist in allowing a team to make an…[Read more]

Hi Mengqiao,

I agree. Understanding the company’s strategy, so IT processes could run based on the company’s business processes IT Strategy is about alignment with the business, understanding what the business is all about and will we be ready to fulfill those needs. As well as, understanding the enterprise direction, defining the targeted IT…[Read more]

Pascal,

I agree. IT strategy is about alignment with the business and making sure we understand what the business is looking to achieve and ensure that IT will be ready to provide those needs. IT should understand the direction of the company, and have defined target IT capabilities. As you stated this is an ongoing process, and I believe…[Read more]

Hi Pascal,

Great scenario! This happens often and it is important to keep in mind that IT must align with the business’s objectives. Therefore, if the C-level executives insist on implementing a system that may fail in the near future then we as IT professional must allow them to make the best choice for the organization. However, it is vital…[Read more]

If I were a member of the IT Strategic Development Team for the company, I would align the IT organization’s strategy with this company by first gaining an understanding of what the organization is trying to achieve. IT strategy is about aligning with the business and having a deep understanding of the business, thereby being prepared to fulfill t…[Read more]

Hi Yingyan,

This is a great example of how stakeholders make a difference in completing or not completing a project. I like how you tied in your application process and the success of it relying on the reference letters. Stakeholders can be the driving force behind a project moves forward, so it is important to have stakeholders buy-in early on.

Karabo,

This is a great example of stakeholder buy-in and the impact they have on the system. New technology is always hard to gain buy-in on. The fact the financial institution was able to demonstrate their product this way was allowed them to gain the stakeholder’s (user) approval. Stakeholders sometimes have more of an interest something…[Read more]

Hi Ami,

This is a great example of the stockholder interest in the project, and how their involvement affects the project. I use to live at Red Lion and the Blvd. so I am very familiar with the location you described. They have been going back and forth for years about the reconstruction of Woodhaven Rd. and I never understood why. I can’t…[Read more]

Hi Xiaomin,

Yes, I agree. Time management is a huge risk and the simple fact that both Juanita and Sally are knowingly busy from the beginning it would be in the best interest of the project if they chose other members that weren’t so busy. In Ami’s post above she mentions pulling other store managers from different customer frequency. I…[Read more]

Hi Iyana,

Great point with your comment about managers disengagement. I noticed that as well No one from the management team is participating directly in this project. There is no real true buy-in and in reading both scenarios there are issues that have set this project up for failure and I believe this is also one of them.
