The third principle of effective customer-supplier relationship which states that the relationship must be based on trust rather than suspicion was described as pattern of collaboration by .

The correct answer is Joseph Juran.

Explanation:

Joseph Juran was an engineer and business and administrative consultant who revolutionized the concepts around business administration and quality management at different levels of production.

The contributions of Joseph Moses Juran (1904-2008) to business administration are immeasurable, so much so that he is regarded as one of the fathers of quality management.

Juran's definition of quality, adaptation to use, suggests that it must be considered from internal and external perspectives; that is, quality is related to product performance that results in customer satisfaction; products without deficiencies, which avoids customer dissatisfaction.

The way products and services are designed, manufactured and delivered, and field service contribute to adaptation to use. Therefore, the search for quality is considered on two levels:

the mission of the company as a whole is to achieve a high quality of design; and the mission of each department in the company is to achieve high compliance quality.

Juran's recommendations focus on three main quality processes, called the Quality Trilogy:

quality planning, the process of preparing to meet quality objectives; charity control, the process of meeting quality objectives during operations, and quality improvement, the process of reaching unprecedented levels of performance.

Quality planning begins by identifying customers, both internal and external; determine your needs; translate customer needs into specifications; develop product characteristics that meet those needs, and develop processes capable of producing the product or providing the service. He wanted employees to know who uses their products, whether in the next department or in another organization. Thus, quality goals are established aimed at satisfying the needs of customers and suppliers alike at a minimum combined cost. Then, the process by which a product is obtained must be designed in order to satisfy customer needs and meet quality goals under current operating conditions. Strategic quality planning (similar to the company's financial planning process) determines short-term and long-term goals, establishes priorities, compares results with previous plans, and combines the plans with other corporate strategic objectives.
