Organizations should not assume they know what the customer wants

Customer satisfaction is defined as a measurement that determines how happy customers are with a company’s products, services, and capabilities. Customer satisfaction information, including surveys and ratings, can help a company determine how to best improve or changes its products and services.

An organization’s main focus must be to satisfy its customers. This applies to industrial firms, retail and wholesale businesses, government bodies, service companies, nonprofit organizations, and every subgroup within an organization.

• Ucustomers and ensuring that they have a positive experience with the company's goods and services.
• A second important metric related to satisfaction is willingness to recommend.
• Customer satisfaction are studied from different perspectives.
• Customer perception of the performance of that product after using it..

Preventing mistakes and defects in manufactured products and avoiding problems when delivering products or services to customers

Defining what suitable product or service quality means has been a more difficult process, determined in many ways, from the subjective user-based approach that contains "the different weights that individuals normally attach to quality characteristics," to the value-based approach which finds consumers linking quality to price and making overall conclusions of quality based on such a relationship

• Many countries manufacturing capabilities that had been destroyed during the war were rebuilt.
• Involved two key people in the development of modern quality concepts.
• Sampling to remove defective products from production lines, essentially unaware of or ignoring advances in QA for decades.

Implementation of inspection and structured testing as a measure of quality assurance in a television set software project at Philips Semiconductors is described

A service is a discrete unit of functionality that can be accessed remotely

A principle to ensure services have an adequate size and scope. The functionality provided by the service to the user must be relevant Services are decomposed or consolidated (normalized) to minimize redundancy. In some, this may not be done. These are the cases where performance optimization, access, and aggregation are required

A service presents a simple interface to the requester that abstracts away the underlying complexity acting as a black box. Further users can also access these independent services without any knowledge of their internal implementation

• Implementation and maintenance of software. An API can be thought of as the service.
• Over a network in order to allow users to combine and reuse them in the production of applications.
• Passing data in a well-defined, shared format, or by coordinating an activity.
