From ages human error studies/ research have proved that there is generally no way to remove the

Two computer systems that will be considered are McKesson and Epic. In this scenario the facility is using paper charting for documentation. I have worked at a facility with this type of charting. While we had paper charting, we had a computer system for lab results and radiology reports. This computer system was McKesson. Therefore I will use this example for my project.

Options A, B, and C. This chapter has three options depending upon your previous experience with a manual version systems project called the Systems Understanding Aid, written by the same authors as this computerized project. Option A is for students who have not used the Systems Understanding Aid before. Option B is for students who have completed the Systems Understanding Aid before using Transactions List A (Document No. 1). Option C is for students who have completed the Systems Understanding Aid before using Transactions List B (Document No. 1).

This section gives the details and specification of the hardware on which the system is expected to work.

As the information system is designed, implementation decisions describing how the system will work are made. Data flow diagrams offer those implementation details, including data stores that refer to files and database tables, programs and human actions that perform processes. The automated parts of the system are differentiated from the manual parts by the human-machine boundary (Dennis, Wixom,

Using the tables from Task 1, design and implement suitable data entry forms which incorporate features to ensure the validity and integrity of data. You must include the following:

Spreadsheets – displays data in a grid of columns and rows, with the capability of easily recalculating numerical data.

Make sure I understand what the user intends to do and what version of Excel the customer is using.

| * Customized user interface with table inputs * Custom-designed parameter screens * Automatic model creation from external data sources (e.g. Excel spreadsheets, databases, or ASCII text files) * Software execution from another application * Model building via programming

23) __________ systems integrate data from a variety of sources, process that data, and produce and deliver formatted reports to users

According to Wikipedia….. “A formal written test-case is characterized by a known input and by an expected output, which is worked out before the test is executed. The known input should test a precondition and the expected output should test a post condition.

➢ Diagrams the functions of the existing system necessary for the development of the new system.

Each step is addressed completely before moving onto the next step, and once in a given step of the process, there is usually no going backwards. This method favors a disciplined approach to development,

The interview session has been done by include an open-ended and closed-ended question which are related to the implemented project. Next, sampling technique is executed by system analyst who does evaluation to the current system or prototype. These processes give feedback in evaluation form that filled after tested the system. Lastly, observation is performed by using questionnaire form. According to Burch (1992), the questionnaire is analyzed and transform into structured form that easy to understand. After all information has been collected, structuring of system requirement takes place. It focused on development process modeling which perform “graphically representing the process, or actions, that capture, manipulate, store, and distribute data between a system and environment” (Hoffer, George, & Valacich, 2012, p. 182). In this step, Data flow diagram (DFD) is structured by system analyst using special tools and techniques to create a decision table. According to Hoffer, George and Valacich (2012), decision table is a “diagram of process logic where the logic is reasonably complicated” (p. 200). This table is useful to help system analyst to make a decision toward the project. Then all information’s gained from this phase are documented in System Analysis Report (SAR) that acts as a guideline or reference to the future system development project (Burch, 1992).

Writing efficient software to accomplish a given task is only half of the battle. What might not be obvious at first in the software development process is the time it takes to fully test your software. It is almost impossible to write a piece of software that is completely bug-free. Code gets complex very fast, as more and more dependencies and control flow paths are added. This report will cover the extensive testing and debugging process in detail for a small data entry program.

This process is carried out to test the application has the required user functions. For this test, I
