Evaluation Of A Prototype Model

The first milestone will be concept approval. During this phase, feasibility studies and basic system concepts have been approved by the management. The project is on course to proceed according to the detailed requirements. The next milestone is requirements review. During this stage, requirement specifications are ready, correct, and approved for input to the design. The next milestone will be preliminary design review here the architectural design meets all product requirements. Critical design review will then follow. During this phase, the detailed designs are approved and suitable for the development of test cases. The next milestone will be the test plan review, which involves reviewing the test plan to ensure product features are satisfactory. The next milestones will be tested readiness review, system test review, operational readiness review, and operational product

I. Concept Stage - Client Representative or CEO meets with Product Manager to describe big picture the goals for end product for spec generation.

The primary errand in comprehension an approach to construct a system is procedure what a system is and seeing anyway it's utilized to encourage a business meet its destinations. A system could be a joined grouping of gadgets and completion frameworks, similar to PCs and servers, which will correspond with each other. Systems convey data in numerous mixed bags of situations, together with homes, minor organizations, and tremendous endeavours.

Another way of successfully gathering information is by building a prototype or model of the system, so that users can test or get an idea of what the finished product will be like. With this they can determine issues, problems, or inconsistency with the system. Another important part of gathering information is organizing it so that it can be understood and put to proper use. I propose categorizing the requirements into functional requirements, operational requirements, technical requirements, and transitional requirements. The functional requirements define how the user thinks the system is functioning overall, the operational requirements define what background processes need to be executed in order for the system to work optimally over a period of time, the technical requirements define what technical issues that must be addressed in order to successfully implement the system, and the transitional requirements define the processes or steps needed to implement the system smoothly and successfully. ("Mind Tools", 2012).

These approaches may be used at any stage in the process, although 'discount usability engineering' assumes the existence of a prototype that can stand on its own.

Design of develop – Once the user stores have been interpreted they are translated into either UI or template design by the development team. Quality Analysis – The prototype is subjected to the quality testing procedure that is mentioned in the above chapter to maintain design integrity. Client Review – This task is optional and can depend on the iteration.

For the needs, I had to use many verbs to help describe the issue. For the insights, I needed to dig deeper and think about their feelings and perspective so I have more ideas to create my prototype. The third step of the process is ideate where I needed to think of five different ideas to help solve the problem when I prototype it. The five different ideas that I had were a lie detector, the guidance counselor, a diary, talk to Paloma’s parents, and an apple tart bake sale. Like I said before, I chose the apple tart bake sale. Also, during this stage I needed to brainstorm ideas of how I will prototype it, how it will look, and how it will operate. The fourth step is prototype where I needed to construct a 3D object that would help solve the problem. During this step I needed to come up with different ideas of how to construct my prototype such as the color, size, details, etc. After prototype comes feedback where I would go back to my user and see what I would need to

To accompany the prototype during the presentation, a handout and slide show will be produced. The single-page handout will provide information on the proposed solution and will be distributed during the presentation Although work has begun on the slide show, the presentation still requires practice.

B) The stage gate process is an iterative project management tool in which a project is divided into stages and separated by gates. The rapid prototyping process on the other hand is a product development method that emphasizes more on adjusting/changing the requirements according to the knowledge gained as the project progresses rather than the traditional approach of rigorous planning before the development

Create – During this step you implement your plan and create or build your design. Also during this step, we test and try our

Competitive Prototyping (CP) is a mandatory process in the Department of Defense (DoD) acquisition system in which, two or more competing teams develop prototypes during the early stages of an acquisition or procurement phase for the purpose of comparing then choosing the prototype that best addresses key issues, problems, or challenges. The mandate for CP has its roots in the DoD 5000 series of regulations governing the Defense Acquisition Management System. Prior to 2008, several revisions of the 5000 series periodically included mandates for CP. The latest revision was in 2008, when the Under Secretary of Defense for Acquisition, Technology and Logistics, issued a new DoD instruction (DoDI 5000.02, Dec. 8, 2008) which contains

The current process: In 1990s a development process was entailed which is 60-month-long. Two major prototyping

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).

4. Development: The development stage is where the company 's creates specifications of the product, the design, and prototypes. It is also in this stage that the company considers manufacturing constraints.
