If the cost of fixing a defect in the requirements phase is 1 what is the relative cost of fixing a defect in the Testing Phase?
It is safe to estimate that the cost of fixing a problem increases by roughly an order of magnitude in each phase of development.requirements phase (cost 1)preliminary design phase (cost 10)detailed design phase (cost 100)coding phase (cost 1000)testing phase (cost 10000)So as an estimate if a problem is not found until test phase it will cost roughly 10000 times as much to fix as it would if the problem had been found in the requirements phase.
How do you hook up a 3 phase water heater to a 3 wires 1 white 1 black 1 bare copper ground?
In order to answer your question, firstly, we have to accurately establish your supply.Is it 2 phase or 2 wire?2 phase is two active conductors, i.e. 2 live wires with reference to neutral or ground2 wire is single phase, an active and a neutral conductor.2 phase supply is uncommon.Single phase (2 wire) is the more common supply and for installations with large loads three phase, or, more appropriately 3 phase and neutral (4 wire) is used.Please confirm your supply so that a detailed answer can be provided.
Why do you have voltage to ground but not voltage phase to phase?
There is phase to phase voltage in 3 phase system.AnswerYou don't get voltage 'phase-to-phase'; it's 'line-to-line'!
What are the three types of phase on its final phase?
single phase, double phase & three phase
How can i Obtain 3 phase secondary service from single phase primary from the utility?
Often the advantages of three-phase power for motors and other 3 phase equipment make it worthwhile to convert single-phase to three phase power. Rural business or farm properties, and urban residential area power consumers, may not have access to a 3 phase supply, or may not want to pay for the extra cost of a 3 phase service, but may still wish to use three-phase equipment. Some of such 3 phase converters may also allow the frequency (see also frequency converters) to be varied allowing for different equipment frequency requirements (50Hz, 60Hz, 400Hz, etc.) and also for motor speed control (VFDs). Some locomotives are driven by 3-phase motors with 3 phase converters converted from the incoming supply of either DC or 1 phase AC. The two main types of 1 phase to 3 phase converters are Rotary Phase Converters and Static Phase Converters. Read below for more about 3 phase converters.There is a big difference between phase converter types available on the market today. Most 3 phase converterssold by companies today do not produce actual balanced 3 phase power. This is why is very important to select a 3 phase generating phase converter which will run on single phase power and generate true balanced smooth 3 phase power. Below is a comparison of several technologies available today.3 Phase Converter Types and Comparison Good old fashioned research will help guide you to make sure that you are able to get the proper product to give you balanced 3 phase power. The US Phase Converter Standards Organization has some excellent guides to help choose the appropriate technology for your need comparing them side by side. Check out their Phase Converter Type Comparison Chart to read about the strengths and weaknesses of each type side by side with their ratings on quality, durability, safety, and 3 phase power quality produced.
Which phase of the system development life cycle generates a detailed plan for programmers to follow?
During the DESIGN PHASE of the SDLC or "System Development Life Cycle" is where a detailed plan for programmers to follow is developed.

Britain focused their full attention to the United States.
Does the moon phase effect the stock market?
No. Those are just rumors, the moon phases do not affect the stock market.
What does market moving sideways mean?
A sideways movement is the movement of prices between a strong support and resistance. This is called a consolidation phase. During this phase the supply and demand are tight. The market tends to consolidate during this phase before it starts to make a movement higher or lower.
How does cnc machining process fit in the new product development phase?
market analysis phase information is gathered by surveying the customer or clients such as feasible study of new products.Specification phase can be collected either from the customer or within the organisation in the form of requirement, technical, pass design or pattern standard.Design/Development Phase Ideas or market requirement are given specific physical form- initial sketching or conceptual design through prototype development to detailed drawings and specifications needed actually to make the product. CNC machining could be used in producing the model of the prototypePreparation phase generally groundwork preparation of tools in making the productManufacturing phase start up of the manufacturing of the product. manufacturing can be done using cnc machine tools if needed.Involves marketing, sale and delivery of products.Bring to customer phase
How LASER radiation is different from ordinary light?
It is coherent: all the same frequency, all in phase, does not disperse as fast (stays focused).
What are the phases of fast methodology?
FAST methodology typically consists of four phases: Focused, Agile, Simple, and Timely. In the Focused phase, the team identifies the key elements of the project. The Agile phase involves quickly developing and testing potential solutions. The Simple phase focuses on simplifying the solution to its most essential components. Finally, the Timely phase ensures that the project is completed within the expected timeframe.
