I appreciate your comment and your explanation of the considerations. For all of these approaches it is also important to consider the data conversion process as this is a big risk for organizations and can be expensive.

You make a great point on the importance of deployment in phases. With a direct installation, users are truly at the mercy of the new system. Any errors resulting from the new system will have a direct impact
on the users and in some cases how the organization performs its business, depending on the
critically of the system to the organization.

You made some great points in weighing the pros and cons of each installation. As mentioned while parallel has the crucial benefits in regards to risk aversion, it can be difficult to get user buyin in comparison to those systems they are already familiar with.

Thank you for tying the security into existing regulatory requirements. This was very helpful in ensuring security of the applications in the cloud. Especially as this is a key concern of cloud computing solutions, along with reliability and regulation compliance.

Thank you for your feedback. Your list of key things to consider for cloud provider selection is very help. Another key consideration that is often overlooked is maintenance and support of the solution(s).

Thank you for your comment. You provided great feedback regarding how the design of Zymr can meet their pick-up and delivery needs especially related to ensuring Internet design consistency, service management issues influencing customer loyalty, and security.

The University at Buffalo”s Assistive Technology Training Online Project is a great tool to help prototype and assess the usability of your system/software. Your comment also brings up a great point that during the process of designing forms and reports, it is important to consider ‘who will use the form or report’ with an open mind when c…[Read more]

I also found information on visual impairment. You give great examples of systems we interact with daily that would present a challenge. You also bring up a great point that ALL consumers or users should be considered in system accommodation and development. Variations in users (i.e. disabilities like visual impairment) influence the usability of systems.

You bring up a great point, that while this disability may not be extremely prevalent it is important to also consider the severity of the condition for users and how it will effect their interaction with the system.

I appreciate your explanation of the different types of encryption. The type of encryption needed will definitely vary. That is why it is important to have a firm understanding of not only what kind of data will be within the database but its relation to the organization. This requires input from both team members and the database designer to…[Read more]

Your comment was very insightful in explaining all the different roles that should be required in the designing a database. As you mentioned, it starts with gathering requirements which requires a collaborative effort. This can help prevent things like missing essential data in the database. I also agree that the solution should be evaluated on…[Read more]

I appreciate your information on the processes included in database design. I agree that the determination of the data, relationships, and logical structure require input from the team members that will be interacting or using the solution. Thinking through these elements are a critical information gathering experience for both the team and…[Read more]

I agree. It is insightful of you to explain the differences between both the database designer and database developer role. It is also important to consider the database administer when designing a database. They will be responsible for performing the day-to-day task of maintaining the database environment to ensure its availability and that it…[Read more]

Mahugnon you mention an important point that we must make sure the relationships remain the same throughout the different models. This can be a red flag if we notice differences in how the “actors” and “objects” interact with one another as we move into different models.

Ami I definitely agree. It is also important to look at the “old” diagrams to sometimes determine that all of the inputs and outputs of the system are captures. Looking at the “old” can help ensure that our inputs and outputs required by the system are all able to be met. This can make the difference between needed to simply update an existing…[Read more]

Jing Jiang you make an important point that by not cross checking you could potentially decrease the efficiency of the subsequent development process. The goal of UML is to develop models that protected.from variations in the future. Increasing the efficiency during development can help separate those parts of the system that are likely to change…[Read more]

You bring up an important point that while we have many rules for the syntax and design of models it is important to develop this same “attention to detail” in the cross checking rules of various models. I think as auditors, when cross checking diagrams, it is important for us to also evaluate how significant an error found is. For example, is it…[Read more]

You made some great points regarding the benefits of integrated models and the overall purpose of the models. As auditors we need to understand the functional (i.e. use case and activity diagrams), structural (i.e. CRC cards and class diagrams), and behavioral (i.e. CRUD and stat machines) aspects of a system in order to be able to asses the…[Read more]

I agree. You bring up an important consideration that we must also make sure meaningful names related to the attributes. This helps ensure the class diagram is being properly understood because as you mentioned everyone has a diverse perspectives and may interpret a generic attribute name, for instance, incorrectly.

You bring up an important point of making sure we consider the different subsystems as well. This will help ensure all of the data requirements as considered from not sure a high level.
