identify the methodology(ies) you have observed in the systems development life cycle: waterfall, rapid prototyping/rapid application development, object-oriented system development, and/or dynamic system development method.

In your current practice area, identify the methodology(ies) you have observed in the systems development life cycle: waterfall, rapid prototyping/rapid application development, object-oriented system development, and/or dynamic system development method. Choose one of the systems and apply it to the current system that you are using. Answer the following:
1) Have any of above models been used in your practice area? 2) Have they been effective for planning and implementing new systems? Why or why not?
3) What barriers have prevented successful implementation?
4) Identify a clinical informatics problem in your practice area in need of change.
5) What recommendations would you make?
6) How would you go about implementing this change?

According to Royce a famous computer scientist, original waterfall model, had the following phases in this order:
1.Requirements specification resulting in the product requirements document
2.Design resulting in the software architecture
3.Construction (implementation or coding) resulting in the actual software
5.Testing and debugging
As you think about this model talk about how the systems you currently use might apply to this model understanding that as one moves thru each phase they can only proceed when its preceding phase is reviewed and verified
The RAD (rapid application development) is a model based on the concept that higher-quality products can be developed faster through more expedient processes, such as early prototyping, reusing software components and less formality in team communications. This model works at a higher level has more urgent needs. Does this model apply to your current system.
• This model uses a combination of systems development life cycle and object-oriented modeling and programming.
• Object-oriented modeling makes an effort to represent real world objects odeling the real world entities or things (e.g., hospital, patient, account, nurse) into abstract computer software objects.
• All of the interactions or exchanges take place between or among the objects.
• Is this system similar to the one you are currently using?
