SNHU Standard Object Quality of Te Product Discussion Business Finance Assignment Help
Define quality in your own words. Considering your definition and the materials you reviewed this module, why is quality so important to an organization?
Find an example of a company that has experienced a quality problem and describe the situation and its ramifications. Was the problem ever fixed?
In response to your peers, discuss an alternate solution that could be employed to resolve the issue.
Peer1: Hello everyone,
When I think of the word “quality” I think of something that is made up of or made with the highest standards. It is a distinctive characteristic that makes a person or thing stand out from others. Quality is important to an organization because it can help increase sales and reduce an organization’s costs, which in turn can increase profitability. An increase in sales often leads to an increase in production, an increase or lowering in selling prices, and an improvement in reputation.
One company I know who has failed in the last few years in quality is Johnson & Johnson. As a top baby product company, they have been good for the most part in the past few decades. Recently Johnson & Johnson had been forced to recall majority of their products from Baby Shampoo’s, Baby powder, and even Tylenol. Tylenol was recalled from Johnson & Johnson due to being laced by cyanide. The children’s and toddlers Motrin were recalled due to having small particles of plastic in it. These are just a handful where the quality was poor within the company. J&J wanted to remain on top and to be one of the best in the industry and started cutting corners, due to their cutting corners and mistakes they have had multiple million-dollar lawsuits and lost customers across the globe. “Johnson & Johnson is the world’s largest health care company. It is also the highest paid drug company in the world. J&J remains at the top of the Big Pharma list of powerful corporations. It is well known for consumer products like Band-Aids, Johnson’s Baby Powder and Tylenol. Its drugs, devices and products have led to scandals and lawsuits”. (Compton, 2019) “Last year, J&J recalled around 33,000 bottles of baby powder in the U.S. after the Food and Drug Administration said they found trace amounts of asbestos, a known carcinogen, in a bottle purchased online.” (CNBC) I believe J&J has tried to fix their quality issue, but they have already made enough of a big dent that they have lost customers. Yes, there are many people who still are true believers and continue to purchase products but there are many who refuse to purchase anything with their initials or logo.

Peer 2: Hi all
In my words, Quality is an indicator and measurement of companies performance in any business. Quality creates customer value. A high-quality product or services offered by any company lead to a positive impact on the company.
I am a loyal brand person. I have been using Samsung smartphones for almost seven years, and my favorite phone is the galaxy note. In 2016 I had galaxy note 4 when Samsung Electronic company launched galaxy note 7. a few days later, we saw in the media that galaxy note 7 was having an issue with its battery as it was exploding. Videos of Galaxy note 7 on fire were posted on youtube showing explosions. I was worried about my safety as I had galaxy note 4. I thought it might happen to me.
As for galaxy Note 7, this was a quality problem. Battery malfunction damaged Samsung electronics company’s reputation. The sales went down, and its share fell in stock markets. Samsung electronics were very honesty as they took responsibility for what has happened. They became proactive and took action to fix the problem. When they found the issue and solution, they come out to the public to announce a quality assurance program and other safety issues. In doing so, they brought back our faith and confidence in its product. The following year I bought galaxy note. After Samsung has addressed the issue, They come back to recover all customers they lost. Indeed, quality control plays a big role in business success.
Thanks
Wilson

Dallas College University of Texas Arlington Website Visual Analysis Discussion Humanities Assignment Help
Visual analysis of a website. My Website is UTA (The University of Texas at Arlington). You will investigate this website using specific criteria to develop an opinion on the site. No personal statement. 4 pages including works cited, MLA format.
Content criteria for analysis:
1. AUTHORITY
Authority reveals that the person, institution or agency responsible for a site has the qualifications and knowledge to do so. Evaluating a web site for authority:
Authorship: It should be clear who developed the site.
Contact information should be clearly provided: e-mail address, snail mail address, phone number, and fax number.
Credentials: the author should state qualifications, credentials, or personal background that gives them authority to present information.
Check to see if the site supported by an organization or a commercial body
2. PURPOSE
The purpose of the information presented in the site should be clear. Some sites are meant to inform, persuade, state an opinion, entertain, or parody something or someone. Evaluating a web site for purpose:
Does the content support the purpose of the site?
Is the information geared to a specific audience (students, scholars, general reader)?
Is the site organized and focused?
Are the outside links appropriate for the site?
Does the site evaluate the links?
Check the domain of the site. The URL may indicate its purpose.
3. COVERAGE
It is difficult to assess the extent of coverage since depth in a site, through the use of links, can be infinite. One author may claim comprehensive coverage of a topic while another may cover just one aspect of a topic. Evaluating a web site for coverage:
Does the site claim to be selective or comprehensive?
Are the topics explored in depth?
Compare the value of the site’s information compared to other similar sites.
Do the links go to outside sites rather than its own?
Does the site provide information with no relevant outside links?
4. CURRENCY
Currency of the site refers to: 1) how current the information presented is, and 2) how often the site is updated or maintained. It is important to know when a site was created, when it was last updated, and if all of the links are current. Evaluating a web site for currency involves finding the date information was:
first written
placed on the web
last revised
Then ask if:
Links are up-to-date
Links provided should be reliable. Dead links or references to sites that have moved are not useful.
Information provided so trend related that its usefulness is limited to a certain time period?
the site been under construction for some time?
5. OBJECTIVITY
Objectivity of the site should be clear. Beware of sites that contain bias or do not admit its bias freely. Objective sites present information with a minimum of bias. Evaluating a web site for objectivity:
Is the information presented with a particular bias?
Does the information try to sway the audience?
Does site advertising conflict with the content?
Is the site trying to explain, inform, persuade, or sell something?
6. ACCURACY
There are few standards to verify the accuracy of information on the web. It is the responsibility of the reader to assess the information presented. Evaluating a web site for accuracy:
Reliability: Is the author affiliated with a known, respectable institution?
References: do statistics and other factual information receive proper references as to their origin?
Does the reading you have already done on the subject make the information seem accurate?
Is the information comparable to other sites on the same topic?
Does the text follow basic rules of grammar, spelling and composition?
Is a bibliography or reference list included?
Visual criteria for analysis:
#1: Purpose
As simple as it sounds, the most important thing a website needs to communicate is what the website does. There should be clear indications (through text, images, etc.) about what the site is. Is it a news site? A blog? An e-commerce site? Some combination? What industry is it? Mortgages? Pharmaceutics? If a viewer can’t tell within three seconds what the site is, they will probably leave.
#2: Possibilities
Your visitors will want to know what they can do with the site. Can they buy stuff or just read news? Can they comment and post reviews? Can they play games or just learn about them? Visitors also want to know how large the site is. When you walk in a department store, you can get a sense of scale. When you “walk into” a website, it’s sometimes difficult to tell how large it is. Help viewers know if there is a lot to offer by giving them clearly marked sections of the site.
#3: Starting Point
Strangely enough, some websites are hard to figure out where to start. Give your visitors a focal point (or a couple focal points). Don’t let them guess where they need to click first. Visitors have a specific reason for going to your site, so make sure they know where to begin. If they start down the wrong path, you may lose them forever.
#4: Visual Appeal
Aesthetics matter! As much as we would all like to believe that all visitors care about is is the content, it’s not true. The visual appeal of a website has been repeatedly proven to make websites seem more credible. People also believe that the website works better (even if it doesn’t!) if the website looks nice.
#5: Personality
You have total control over your website’s personality. How do you want it to present itself? Informal? Serious? Fun? Excited? Professional? Funny? Every word, image, and color you choose will impact the personality. Keep the personality consistent in your headings, colors, and word choice throughout the entire site. This is an important branding consideration.
#6: Color Scheme
Run your color scheme by a professional designer. Or, at least ask several people what they think (and you can’t ask your spouse or mother!) You shouldn’t have more than 3 or 4 colors dominating your design and all the colors should match. Also, recognize that about 9% of all men have some form of colorblindness, so you may need to accommodate for that, depending on your content.
#7: Welcome Blurb
Similar to a tagline, a welcome blurb quickly (in a sentence or two, or even simple phrases) should elaborate on the tagline. “We don’t just sell baby furniture. We well sell the cutest stuff out there.” DO NOT let your welcome blurb turn into “Happy Talk” (See #29). Welcome blurbs are not always necessary, but they can help clarify the purpose of a website. And they should be very short.
Navigation
#1: A Way Home
I always tell my students: don’t let your website feel like IKEA (or a hospital)! When we walk into most buildings, we know where we are in relation to the front door–IKEA and hospitals are the exception. There is nothing more frustrating than feeling lost. If visitors don’t know how to get back to the homepage, they’ll probably just leave. (If only that were a luxury we could have in IKEA–you can’t just leave until you find the door!
#2: Search
If your website is larger than 15 – 20 pages, you really should have a search bar. Research has shown that about 50% of all web users expect a search bar, and go to it almost immediately on any new site they visit. Don’t count out half of your visitors because you don’t have a search bar. Simple, small sites can get away with not having one.
#3: Page Grouping
The way you group your pages is important. If you sell leather gloves, will you put them under “lawn and garden” or “automotive”? Or both? Make sure the way you group your information is consistent with industry norms and customer expectations.
#4: Organization/Visual Hierarchy
Websites should be organized by importance. Is the most important thing the most obvious? Largest? Highest on the page? Is anything important “below the fold”? (Meaning, is it below the bottom of the monitor, where visitors will have to scroll to see it?)
