Design Assumptions. The basic wireless model that we assume for our analysis and design comprises of a source host which is connected to a base station by a fixed wireline network, and a wireless host, which is just a single hop from the base station. We also assume that the mobile, wireless host receives all its packets through...
design How to handle assumptions while designing any
Usually, overarchitectural design introduces unnecessary complexity to the project. The rule of thumb while designing a software, with premature requirements and assumptions, is to keep it simple. There are number of posts on this topic that combined in a famous phrase YAGNI! In another words, best design patterns to stick with are KISS and YAGNI !
A Project Assumption is stated without any empirical evidence. All Project Assumptions are potential risks. Assumption Analysis is one of the important techniques for Risk Identification. Project Assumptions should be well Documented and well Communicated. Poor Communication of Project Assumptions can, sometimes, lead to Project Failure.
1.2 Assumptions Only authorized individuals can perform change management functions, as explicitly outlined in the proceeding change management policy. In the absence of specific requirements thereunder, no undefined action may be taken without prior approval from the Service Transition Process Manager/Change Manager.
Assumptions and constraints form a foundational basis for project planning, filling in the gaps between known proven facts and total guesswork. Each assumption is an "educated guess", a likely condition, circumstance or event, presumed known and true in the absence of absolute certainty.
ENGINEERING ASSUMPTIONS: REASONABLE DILIGENCE AND BEST JUDGMENT AT ISSUE. Valid assumptions can be made when the engineer has either worked through the numbers on enough occasions to know what effect the assumptions will have on the analysis, or the assumptions are so basic in nature there is no question of their validity.
Often assumptions are used as a starting point for a course of action or reasoning. The reliability of the result depends on the reliability of the assumptions. Design decisions are usually influenced by a lot of information. Some of it is given in the problem.
The 4 Design Assumptions Costing You Money Usability Geek
Design Assumption 4: Users Use Your Site Under Ideal Conditions This is especially true with your mobile users devices. Whether its having to turn down the backlight on a mobile device or laptop to conserve power, or using the device in direct sunlight, there are many different instances when your users wont be viewing your site or app under ideal conditions.
bounding assumptions and associated data in order to bracket the solution. The key is to recognize the characteristics of a situation and to apply a model that is neither unnecessarily complicated nor one that is oversimplified. That boils down to applying only assumptions which are known to be valid so that the results will be reasonably accurate.
