The first step in the usability process is to study the intended users and use of the product. At a minimum, developers should visit a customer site so that they have a feel for how the product will be used. Individual user characteristics and variability in tasks are the two factors with the largest impact on usability, so they need to be studied carefully. When considering users, one should keep in mind that they often include installers, maintainers, system administrators, and other support staff in addition to the people who sit at the keyboard. The concept of "user" should be defined to include everybody whose work is affected by the product in some way, including the users of the system's end product or output even if they never see a single screen. Explain four (4) benefits when know the user

Use the usability criteria you've developed to compare and contrast the two alternative designs. Can your needs really be met? Is it always easy to read the time and other details offered, or do you occasionally have trouble doing so?
incremental developmentIncremental development is based on the idea of developing an initial implementation of the system, getting feedback from the users and other stakeholders, and evolving the system through several versions (increments) with small incremental improvements until the required system has been developed. Incremental development can be plan-driven, agile, or both.iterative developmentIterative development is an approach to software development in which the processes of specification, design, development, and testing are interleaved, repeated, looped, or iterated through multiple cycles as a means of refining the system with each new pass.Incremental development is almost always iterative, but an approach can be iterative without being incremental. Consider the incremental models and the iterative models introduced in this module. Both models provide a great deal of flexibility to accommodate requirements changes. Which one would give you the most flexibility to change…
How important is it to have a consistent user experience while developing the SoS interface? How affordable is having one interface? What elements come into play while making a decision of this nature?
Testing for quality assurance in software is the subject of discussion. Let's say you're helping to build a website for a consortium of universities. Please give comments that are both comprehensive and informative, as well as reasons for the options you've selected. a) Outline which kind of testing strategies are suitable for the project. b) If you were in charge of the testing for the project, why and how would you do it?
Note : Since we only answer up to 3 sub-parts, we’ll answer the first 3. Please resubmit the question and specify the other subparts (up to 3) you’d like answered When a component is reused efficiency is increased as much of the component is already completed, consistency is increased as control and scalability is enhanced on it, testing is reduced as components are already tested, etc. Step 2 a) Three components to be reused can be : Tab control Dialog control Calendar control Other parts maybe of login registration page b) Tab control : For flexible navigation a customized tab control can always be reused in different applications. This will increase efficiency . Dialog control : To manage some kind of action when one exit app or switch between different sections can be reused. Calendar control : This is almost a part of multiple applications and one may use it for interaction with dates. User selects single or multiple dates. A customized component can be reused…
You are eliciting needs for a new version of an existing product that is currently under development. List one elicitation method that would be effective in addressing each of the needs elicitation issues mentioned in the next section (one technique per problem). Explain briefly why this approach is appropriate in this situation. Rather of just listening to what users say they do with the current system, you should investigate how they really utilize the system.To do this, you must first decide which aspects of a new suggested system are the most essential and required.
A new project has an average novelty for the software supplier that is going to execute it. Development flexibility is high, and requirements may change radically. The development team is all located at the same office and the software house as a whole tends to be formal in its standards and procedures. The product should be very reliable, and the algorithms are complex. The supplier would like to reuse the project with suitable modifications on further contracts. Developers are familiar with the platform and they are capable of conducting this specific type of project. The toolsets available to the development team are judged to be typical for this size of company, but schedule pressure is tight to meet a deadline.
Several various techniques are used by those who deal with computers and people to gauge how effectively they complement one another.Usability testing is required.Early on in the process, evaluation takes place.
Examine the two various designs using your usability guidelines as a guide. Is it capable of meeting your needs? Is it always simple to observe the time and any other presented information?
How important is it to provide a consistent user experience while developing the SoS interface? Is it economical to have a single user interface? Do you know what swayed this choice?
When building the SoS interface, how vital is it to maintain a consistent user experience? A single user interface is more cost-effective, but is it worth the effort? When making a decision like this, what factors should be taken into consideration?
When it comes to testing on end users, there are three primary techniques to choose from.
