4. Do you think that information appliances like PDAs will replace personal computer (PCs) in business applications? Explain.

Handheld microcomputer devices known as personal digital assistants (PDAs) are some of the most popular device in the information appliance category. Web-enabled PDAs use touch screens, pen-based handwriting recognition, or keypads so that mobile workers can send and received e-mail, access the Web, and exchange information such as appointments, to do lists, and sales contacts with their desktop PCs or Web server.

PDAs have some advantages like smaller size, lighter weight and wireless network functions. They are widely used because of their mobility. For example, iPhone is a great product, and a lot of people are crazy about it. Everyday a vast number of people exchange e-mails and access all kinds of information on their iPhones very conveniently and quickly.

However, I do not think that the information appliances like PDAs will replace personal computer (PCs) in the normal business applications. In this contemporary society, personal computers are regarded as formal office appliances because of their powerfulness and versatility. So, PDAs can hardly replace them in a couple of years because of their shortcomings. For example, they still cannot deal with big documents or save huge size information in their data storage. And because of their mobility, PDAs are always equipped with the touch screen without keyboard and mouse. It is kind of difficult for people to type something for a long time on the touch screen. As a result, people can use PDAs to receive or read e-mails and browse the website, but PDAs definitely still have their limitations.

I believe that PDAs can replace personal computers in the future, but not for now. They should overcome their limitations like difficulty in entering data and small data

New System Proposal

...requires an innovative information system proficient in the organization of product sales, which allows management of data by employees from computers and mobile devices. This new system would contain customer records and be password protected for sales agent’s individual accounts and further promote confidentiality of client and corporate data. Information security and carbon footprints will need to be addressed with creation of a new data warehouse. The cloud computing system would be an idyllic system for addressing the needs of Riordan Manufacturing and would be an inexpensive conversion from the old systems. Cloud computing initially evolved from visualization. The use of visualization would allow Riordan to separate its software, business applications, and data from hardware sources that may experience an issue. The cloud offers storage, network, and hardware virtualization. Businesses can set up private clouds as storage warehouses for company information. Information technology virtualization enhances the business’s assets and offers lower administration fees, reduced maintenance, and consolidation of company information for strategic marketing initiatives in one location. With this in place, there would be less risk of possible loss of important and pertinent information. The entire marketing division would be combined into one superior database for easier comparison of information. Switching to a cloud system would allow a speedier return on information requests from different...

Depending upon the source of the information, we would be classifying this into two categories – internal and external.

Some of the examples are -  Sales figures at each store  Customer foot fall at each store  Merchandise wise sales  Enquiries for product line unavailable  Customer Segmentation at each store – by age, gender, personality types  Salesperson wise sales or units sold  Productivity rate i.e. Number of people who bought something vs. total foot fall  Advertising Campaigns/ POS used at each store  Sales increase post advertising , in-store marketing External Source: In addition to the above, it would be essential that the company also gathers data from outside agencies, from secondary sources like research firms, market, Television, competitors etc. Examples of such data and statistics would include the following –  Number of competitor outlets in the region  Total Market Share of Hot Chile in Mexico  Most popular Surfwear store in the region  Sales Trends in the industry  Growth rate expected...

Meaningful Data

...MEANINGFULL DATA AND INFORMATION. Data consist of raw facts, such as customer names and addresses. For data to be meaning full, it must be collected to constitute information. Information is a collection of data or facts organized in such a way that it has more value beyond the individual pieces of data themselves. For example, a set of data of customer names and purchases might provide information on a company's market demographics, sales trends, and customer loyalty or turnover. Every purpose data or collecting data is to transform them to information. Turning data into information is a process or a set of logically related tasks performed to achieve a defined outcome. This process of defining relationships between various data requires knowledge. Knowledge is the body or rules, guidelines, and procedures used to select, organize, and manipulate data to make it suitable for specific tasks for a specific period of time. Consequently, information can be considered data made more useful through the application of knowledge. The collection of data, rules, procedures, and relationships that must be followed are contained in the knowledge base. Companies face increased pressure to provide higher quality information faster and more efficiently. They want more transparent information in less time. There are demands that information must be faster with more transparency and come from every angle meaning they shouldnt be just providing information from one perspective . Many people...

Meredith Knows Women - Case Study

...Chapter 4 Case Study Meredith: Thanks to Good Marketing Information, Meredith Knows Women 1. Meredith’s marketing information system really focuses on women. Their target market is women and it is obvious in the way they cater towards women. Some of their strengths include they cater to a woman’s progression throughout life, they have studied their customers so greatly that they have over 700 data points on each one, and they have even segmented each individuals interests in order to better serve them. Not only that, but they have so much data on their customers that they can now sell their information to other businesses. As print is a declining business, Meredith has also ventured into the online and television world and is making their presence known. They are not simply looking at the present but are also setting themselves up for the future. A weakness of Meredith is that preferences can change over time. They need to keep up with the changing interests of their customers and make sure their data points are not just a storage bin full of outdated information. Another weakness is that it is only providing to women through magazines and television shows. With all of the information they have gathered, they should be able to reach out to women in other forms such as clothing, exercise equipment, gardening tools, or even cookware. The information that they have accumulated could be used for another business venture. 2.Through impersonal...

There are advantages and disadvantages of easily obtainable information, just like there is advantages and disadvantages to social media, and knowing these advantages and disadvantages may very well alter the way one uses social media. Believe it or not there are advantages to easily obtainable information. One of which is expediency, it is convenient for people to be in one place and catch the hottest news, listen to fresh top songs on the billboard charts, watch and share music videos to those songs, while at the same time holding a conversation through chat multiple friends instantly. It is easier than reading the newspaper, watching TV, listening to the radio, and talking on the phone all at once to achieve the same thing. One can multi-task and do these things efficiently while conforming to society’s intolerant nature. A disadvantage of easily obtainable information is identity theft, which is where critical or sensitive information is available when it shouldn’t be. Another one is the unintentional discovery of finding out a family member perishing in a car accident or some other drastic way before the information is able to be properly delivered. There are many different advantages and disadvantages of social media. Everything in excess is bad. Social media is not...

Using Information

...making takes place within the guidelines set by the strategic plan. Data and information Tactical information will be mostly internal with a few external sources being used. Internal information is likely to be function related: for example, how much ‘down time’ a production line must allocate for planned maintenance. Tactical information is used by middle management (employees) when managing or planning projects. The timescale is usually at least between 6 months and 5 years (depending on the scale of the strategic project). Circumstances vary but a small project may have a tactical timescale of between one and six months. Tactical plans have a medium level of detail and will be very specific; they deal with such matters as who is doing what and within what specific budgets and timescales. These plans have medium scope and will address details at the operational level. They will generally have specific objectives and be geared towards implementation by operational level employees. Operational information The lowest level is operational and operational planning takes place based on the tactical plans. The lowest level of management or workers in an organisation implements operational plans. These may be section leaders or foremen in a large organisation or workers such as shop assistants, waiting staff, and kitchen staff, etc., in smaller businesses where there is no supervisory layer.

Information Use

...Information Use Information Use Information can be used in a variety of ways in today’s world. Companies use it to track profits and losses others use it to see into future trends so they can make informed decisions about where their business should be in a certain market. According to Opara (2003) “Information is the life blood of modern organizations.” Without information organizations would be making decisions blind. Information in a modern organization flows in a circular motion. For an example of how a major car dealership uses information it gathers. A customer who is prospecting for a new vehicle enters a car dealership not sure of what kind of vehicle he or she may want. An associate greats the new customer and asks a few question to discover what the customer is looking for. This would be the input information that the associate will use to enter into an information system (IS) from this system the associate can help the customer choose what vehicle he or she may be looking for. The information is presented to the customer, after looking at the information the customer chooses a vehicle he or she wants to purchase.

The information is used by the finance department to set up the financial obligation that the customer will have to pay.
