1.    Why is selecting a systems development approach an important business decision? Who should participate in the selection process?

 

Software development approach in information systems is a process of creating or altering information systems, and the methodologies that people use to develop these systems. A system development approach is a framework and guide of all the activities involved in system development, facilitates teamwork, sets expectation and communicates timelines, milestones & deliverables. An organization selects a system development approach based on their size, technological complexity and problem/opportunity the system will solve.

2. Some have said that the best way to reduce system development costs is to use application software packages. Do you agree? Why or why not?

I agree to an extent. Application software packages (ASPs) and fourth-generation (4th-G) tools can be used to reduce costs in certain instances. ASPs are typically designed to handle business functions common to all organizations, and company’s can save money purchasing them instead of trying to develop this software in-house. However, ASPs cannot be customized without great cost and difficulty, and thus are not suitable for functions unique to a particular organization. 4th-G tools allow end-users to develop applications with little or no technical assistance, thus reducing costs for most tasks. However, 4th-G tools are not well suited to process large volumes of data, or to perform complicated tasks. In those instances, it would make more sense, and be more cost effective to use conventional tools.

Here is my response to the 2 questions. Look forward to questions.

1. Why is selecting a systems development approach an important business decision? Who should participate in the selection process?

It is important for businesses to select a system development approach that provides a solution to the problem they are experiencing, such as their current system is not being utilized or performing as expected, new opportunities to upgrade or replace their system that will increase efficiency, save time and reduce cost. The system development decision needs to satisfy their needs, objectives and procedures. The IS Project Manager should include owners and the users of the system in order to find the errors in performance and correct them prior to selecting and going “live” with their chosen system. The users are chosen to participate in the development in order to get their “buy in” with the new system. They know firsthand what has been working, what doesn’t work and will suggest alternatives that they feel will improve the system.

2. Some have said that the best way to reduce system development costs is to use application software packages or fourth-generation tools. Do you agree? Why or why not?

I would have to agree that using an application software package (ASP) with a few simple alternations to fit the businesses requirements would help reduce system development costs because someone else has already paid to develop the system to perform the most common functions and there is no need to re-invent the wheel if a large part of the development is already completed. Fourth-generation tools where developed for those who don’t have extensive technological knowledge but has proven that it cannot process large volumes of information or perform difficult functions. Buyer beware because with some ASP systems it may cost too much to make system changes and therefore an in-house system may prove to be more cost effective and easier to simplify.

You need to have 200 to 250 words in each response.  There is not enough words.
