External Components The external components on the front of the computer are shown below. OPERATIONS MANUAL The operations manual is the documentation by which an organization provides guidance for members and employees to perform their functions correctly and reasonably efficiently. It documents the approved standard procedures for performing operations safely to produce goods and provide services. You should include policies for: Administration Sales Customer Service Fulfillment HR Marketing Safety and security Maintenance and repair CERTIFICATIONS The technical expertise in testing and certifying computers and workstations against national and international standards gives the confidence to efficiently bring new and updated products to market. QUALITY STANDARDS Standard is a set of specifications for hardware or software, agreed upon by academic and industry contributors. Common examples of standards include multiple IEEE standards for electrical interfaces (computer cables), ANSI for programming languages, and VESA for computer monitors and video adapters. The intent of standards is to provide at least minimum quality, safety or performance specifications to ensure relatively uniform products and performance, and to remove ambiguity as to the suitability of certain commercial products for applications. 1. HARDWARE It covers all parts of a computer that are tangible objects. Personal computers, laptops, monitors/displays, circuits, power supplies, cables, keyboards, printers, scanners, video, camera and mice are all hardware.  Factors that help determine hardware needs: - PURPOSE OF THE USE OF THE HARDWARE – single user, instructional use, lab work, will the hardware be reused or is it disposable, who are the users (tech savvy or novice), are there infection control issues if used for patient care, etc. - SPECIFIC APPLICATION OF THE HARDWARE – helps you determine the type of hardware, the size of the operating system, need to share resources - BUDGET – how much money is allocated for purchase - MAINTENANCE - who will maintain the hardware, how much maintenance will be needed, who will install updates, etc.  SOME ASPECTS TO CONSIDER WHEN DETERMINING HARDWARE NEEDS: WORKSTATION HARDWARE NEEDS-what type of monitor and keyboard, wall mounted, desk type or mobile. processing power, memory, storage needs, audio and video needs. SERVER HARDWARE NEEDS type will depend on the use, and must consider the size of application, printing, storage NETWORKING-RELATED ISSUES, Ethernet, cables, hubs, switches PRINTING AND OTHER PERIPHERALS (scanners, imaging, video, audio, printers, speakers, headsets, webcam, etc). Type of printers, color, laser, size of paper, number of users that can and need to access printing capabilities. POWER NEED, how much power, via outlets or power strips ERGONOMIC NEEDS of users, accessibility needs, special equipment for monitor glare, special keyboards, adjustable height of equipment FUTURE UPGRADES, how will upgrades be handled, and who will install them LAYOUT OF ROOM OR LOCATION OF HARDWARE-How many users will be using hardware, is there enough room, how should the hardware be set up what is the layout 2. PRODUCTION PROCESS In production process, checking of quality assurance must be highly considered. Quality assurance covers all activities from design, development, production, installation, servicing and documentation. A. FAILURE TESTING A valuable process to perform on a whole consumer product is failure testing, the operation of a product until it fails, often under stresses such as increasing vibration, temperature and humidity. This exposes many unanticipated weaknesses in a product, and the data is used to drive engineering and manufacturing process improvements.  B. STATISTICAL CONTROL Many organizations use statistical process control to bring the organization to Six Sigma levels of quality, in other words, so that the likelihood of an unexpected failure is confined to six standard deviations on the normal distribution. Traditional statistical process controls in manufacturing operations usually proceed by randomly sampling and testing a fraction of the output. Variances of critical tolerances are continuously tracked, and manufacturing processes are corrected before bad parts can be produced. C. COMPANY QUALITY The company-wide quality approach places an emphasis on three aspects: 1. Elements such as controls, job management, adequate processes, performance and integrity criteria and identification of records 2. Competence such as knowledge, skills, experience and qualifications 3. Soft elements, such as personnel integrity, confidence, organizational culture, motivation, team spirit and quality relationships. D. TOTAL QUALITY CONTROL 1. Marketing had to carry out their work properly and define the customer’s specifications. 2. Specifications had to be defined to conform to these requirements. 3. Conformance to specifications i.e. drawings, standards and other relevant documents, were introduced during manufacturing, planning and control. 4. Management had to confirm all operators are equal to the work imposed on them and holidays, celebrations and disputes did not affect any of the quality levels. 5. Inspections and tests were carried out, and all components and materials, bought in or otherwise, conformed to the specifications, and the measuring equipment was accurate, this is the responsibility of the QA/QC department. 6. Any complaints received from the customers were satisfactorily dealt with in a timely manner. 7. Feedback from the user/customer is used to review designs. 8. Consistent data recording and assessment and documentation integrity. 9. Product and/or process change management and notification. 3. FINAL PRODUCT Shows the Quality System Elements required by ISO 9000 in the making of the final product. Quality System Elements 4. CUSTOMER SERVICE is the act of taking care of the customer's needs by providing and delivering professional, helpful, high-quality service and assistance before, during, and after the customer's requirements are met.  CHECKING PROCESS QUALITY CONTROL (QC) IS a procedure or set of procedures intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer. Quality control (QC) is a process by which entities review the quality of all factors involved in production. ISO 9000 defines quality control as "A part of quality management focused on fulfilling quality requirements". It is a Software Engineering process used to ensure quality in a product or a service. This approach places emphasis on three aspects: Elements such as controls, job management, defined and well managed processes, performance and integrity criteria, and identification of records Competence, such as knowledge, skills, experience, and qualifications Soft elements, such as personnel, integrity, confidence, organizational culture, motivation, team spirit, and quality relationships. QUALITY ASSURANCE (QA) is defined as an activity to ensure that an organization is providing the best possible product or service to customers. QA focuses on improving the processes to deliver Quality Products to the customer. An organization must ensure, that processes are efficient and effective as per the quality standards defined for software products. How to do Quality Assurance: Complete Process Quality Assurance (QA) has been called PDCA cycle or Deming cycle. The phases of this cycle are: PLAN - Organization should plan and establish the process related objectives and determine the processes that are required to deliver a high-Quality end product. DO - Development and testing of Processes and also "do" changes in the processes CHECK - Monitoring of processes, modify the processes, and check whether it meets the predetermined objectives PLAN - Implement actions that are necessary to achieve improvements in the processes  Quality System, Quality Assurance, and Quality Control Relationships Difference between Quality Control and Quality Assurance? Sometimes, QC is confused with the QA. Quality control is to examine the product or service and check for the result. Quality assurance is to examine the processes and make changes to the processes which led to the end-product. Examples of QC and QA activities are as follows: Quality Control Activities Quality Assurance Activities Walkthrough Quality Audit Testing Defining Process Inspection Tool Identification and selection Checkpoint review Training of Quality Standards and Processes Records and Documents All records are documents but not all documents are records. Many records start out as documents and then become records when they are finalized. For example, an empty form is a document and then after it is filled in becomes a record. Organization work procedures Organizations use policies and procedures to outline rules and to outline courses of action to deal with problems. Organization policies and procedures make employees understand the organizations views and values on specific issues, and what will occur if they are not followed. Policies are general statements of how an organization want to behave and procedures define exactly how to do a task or perform step by step.A policy can be security related and can be used to identify risks and mitigate risks. POLICIES AND PROCEDURES: 1.All employees must present their identity card. 2.The security guard must thoroughly check the employee’s name, picture, signature, and card issuer's signature in the identity card to make sure that he is an employee of the company.. After checking, the employee will do his biometrics. 3.The face of the employee must be visible in the identity card for security purposes. 4. Once the security identifies the employee; he must scan his fingerprint to access the office. 5. If the employee’s face is not similar with that in the identity card, the security guard should contact the senior officer or the Human Resources Department for verification. 6. If any person who is trying to enter the office without any prove that he is an employee; he will be guided off. BEFORE YOU START It always helps to know what you’re searching for, so make a note of the product model number before you turn to your computer. This will usually be printed on the box and on a (usually difficult to access) part of the product itself, but make sure you get the full product name.  Start at the manufacturer’s website The first port of call for a missing manual should always be the original manufacturer’s website. Most have customer support sections with downloads of all kinds, including digital copies of user manuals.  FORMS It refers to an appearance that can be recognized. Forms are often used to mean an area defined by contour without regard to other identifying qualities or materials. Example of Log Report Form (to be completed by the quality checker) Date Received O.R. # Item Name Quantity Signature Quality Checker Example of Assessment of Materials Received FORM (to be completed by the Quality checker) Quality Checker Date: Item Name Total number in Total number of Comments good condition errors
