Chapter-12 Fit Criteria and Rationale
FORMALITY GUIDE
Horse ventures need to have an exact and effectively shareable comprehension of the significance of necessities. It has been our experience that when the task has numerous partners—which is the standard for horse ventures—various partners relegate various implications to prerequisites. Including a reason and a fit basis to every necessity implies it is for all intents and purposes inconceivable for errors to happen. We prescribe that pony ventures incorporate both of these in their necessities.
Elephant ventures must utilize methods of reasoning and fit criteria. These tasks are compelled to deliver a composed determination to be given on to some other gathering, either another piece of the association or an outsourcer. Having a detail containing just unambiguous, testable necessities is pivotal to elephant ventures on the off chance that the other party is to comprehend and, at that point convey the right item
Scale of Measurement
Any prerequisite can be estimated: All you need to do is locate an appropriate scale with which to gauge it. The size of estimation is the unit you use to test the conformance of the item to its necessity. For instance, in the event that the prerequisite is for a specific speed of activity, at that point clearly the scale is time—microseconds, minutes, months—to finish a given activity or set of undertakings. For an ease of use prerequisite, you can gauge the time expected to get familiar with an item, or the time taken before accomplishing a specific degree of skill, or maybe even the blunder pace of the work done utilizing the item. Sizes of estimation exist for a wide range of characteristics. Shading can be estimated by determining its part hues as a level of cyan, red, yellow, and dark. Clamor and delicate quality of sound are estimated as far as decibels. A measure of light is estimated in units of lumens. Typefaces can be estimated by face names and point sizes. Actually, there is a size of estimation for nearly everything.So far, the only thing that your authors have not been able to find a scale of measurement for is love—we cannot find any way of measuring how much you love someone. Readers are welcome to send suggestions.

DERIVING FIT CRITERIA
ReplyDeleteTo come up with the appropriate fit criterion, start by analyzing the description and rationale you have established for the requirement.
Now you know the requirement is about speed—which is fairly easy to quantify—and awkwardness—which is about complexity and perceived ease. For the speed component, imposing a time limit for a search is appropriate. Suppose your market research personnel tell you 10 seconds is the limit of the target audience’s tolerance; to be better than the competition, you are shooting for 6 seconds for your own product.
In terms of the awkwardness component of the fit criterion, your ergonomics personnel and market research both say that buyers must be able to find a piece of music in no more than three actions (an action here means a click, a gesture, a menu selection, voice command, or
any other conscious action on the user’s part).
Your measurement for these things would be this fit criterion:
Fit Criterion for Functional Requirements
ReplyDeleteA functional requirement is something that the product must do an action it must take. The fit criterion specifies how you will know that the product has successfully carried out that action. For functional requirements, there are no scales of measurement: The action is either completed or not completed. Completion depends on satisfying an authority that the product has correctly performed the action. The authority in this case is either the source of the data or the adjacent system that initiated the action.
Functional requirements can be written for different kinds of action. For example, if the action is to record something, then the fit criterion is that the recorded data complies with the data as known to the authority. For example:
Description: The product shall record the weather station readings.
Rationale: The readings are necessary for preparing the de-icing schedule.
Fit Criterion: The recorded weather station readings shall be identical to the readings as recorded by the transmitting weather station.
When requirements are measured it helps to disclose its importance, or sometimes non-importance. As mentioned before by my teammates, fit criterion is the measurement of the requirement. When a system has a requirement regarding its performance to some function, testing will tell you if the product does indeed perform or possess the desired property. To carry out tests, the requirement must have a benchmark so tester can compare what is delivered versus the original requirement. The benchmark is the fit criterion, "a quantification of the requirement that demonstrates the standard the product must reach".
