Project #77096 - IT-210 (3 paragraph discussion)

Good evening scholars, 

I am needing my discussion post completed; due date is 07/23/2015 (Thursday) by 6pm Pacific Time. 

Here is the topic for the discussion question which needs to be a minimum of 1 paragraph (2 paragraph max)

 

“Developers use the system development life cycle to map out a project from the planning phase to maintenance. In information systems, change is required to implement new software or hardware. How can the system development life cycle be used for changing from a brick-and-mortar store to creating an online presence?

A project manager can use project management to create a plan for change. What are some of the reasons a project may fail or succeed? What steps can be put into place to ensure success and limit failed attempts? Provide specific examples from the textbook or other sources to support your answer.

In responding to your peers, consider how the seven phases of system development life cycle and three software development strategies can minimize the risks of change. Provide specific examples from the textbook or other sources to support your answer.”


If needed, here is a link for the seven phases of system development life cycle http://petersheehan.blogspot.com/2009/01/seven-phases-of-systems-development_11.html

Software development strategies http://www.informit.com/articles/article.aspx?p=605374&seqNum=2



Next, you will need to reply back to these user’s discussion posts as well (minimum of 1 paragraph) (2 paragraph max)

 

#1 (planning for change)

   The system development cycle can directly correlate to a physical building transferring to an online presence. Both require the planning phase, when a business initially looking at e-commerce options they need to do extensive planning to ensure success. Analyzing and designing both correlate as exact copies. Testing and eventually maintenance are valid steps to creating an online presence too. When implementing an online presence, it is important to test it thoroughly before releasing to the public.

Projects can fail for a large amount of reasons. I think the biggest cause for failure is poor planning. I have seen many projects and have had many of my own projects fail because of poor planning. Just like a house a project needs to have a strong foundation. Team conflict can be a big cause for failure as well. If a team cannot function together properly then the project is in danger of failing. Although there are many other reasons I believe these are the two most common reasons a project fails.

 

 

#2 (Planning for Change Part I)

A System Development Life Cycle (SDLC) can change a brick-and-mortar store into an online presence through planning, analysis, design, development, testing, implementation, and maintenance. Through the first stage of planning, a company can determine what the business needs are and allocate funding for the development of a new information system. Return on Investment (ROI), competitive advantage, and risk management are three factors to consider during the planning stage. Financial, technical, and legal needs must also be explored. Once the planning and analysis phases are complete, the project can move into the design phase of the project.

Depending on whether the company choses to build or buy, the next process may differ. Generally, a prepackaged software should meet at least 75%-80% of the requirements. Building a new software system involves architectural design which includes software development and hardware. Service Oriented Architecture (SOA) is growing in software design. Data models and database design shows how the how the components will work together to achieve the goal, Database schema will show details for database tables and its fields along with the relationships between tables. Use case diagrams show how each user will interact with the new system. Designers may use Unified Modeling Language (UML) to create visual models and blueprints to document the system components as well as record performance behavior. Once the design phase is completed, developers can move into the development and testing phases.

The design is then converted into an operational information system. Developers may use software such as version control software to track versions of codes and prevent other developers on the project to write over another’s file. Likewise, project and issue tracking software helps developers keep track of the project, upload diagrams, report bugs, describe challenges, request assistance from other developers, and checks for security vulnerabilities in the codes. Moving to the testing phase, testing consists of several steps that include unit testing, system testing, stress testing, parallel testing, integration and acceptance testing and involves end users, IT staff, and developers.

The final phases are implementation and maintenance. There are three choices for organizations to implement the new IS:

Parallel implementation is when the new system is launched while the old one is still in use- this option can be costly, however, it is only in place for a short period of time.

In phase implementation, the new modules are launched in phases (e.g. one department at a time). This option may require temporary interfaces to the old system.

And finally, direct implementation, which switches the old system off and launches all of the modules of the new system. This option works well for small systems and is not recommended for complex software that involves thousands of employees.

 

The final phase is maintenance. Maintenance includes support for first few weeks to fix any glitches, issues, and ensure that employees have access to the need functions. Once this process is completing the regular help desk support staff can take over. Maintenance is also required for bug fixes and change requests, as well as supporting changed in requirements, integrating data in the event of a merge, changes in government regulations, and keeping the system up to date and secure.
