  • Course Overview
  • Course Outline

This two-day course addresses the principles and methods of designing things, regardless of what is being designed. The training provides an integrated approach to the set of technical design process disciplines. These combine with technology knowledge to contribute to the satisfaction of requirements and optimization of system effectiveness, enhancing project success and reducing risk to the enterprise.

This course is recognized by Engineers Australia for CPD purposes (16 hours). This course is recognized by Engineering New Zealand for 16 CPD hours (click here for details). This course may be credited toward the maintenance of the INCOSE Certified Systems Engineering Professional (CSEP) accreditation for 16 Professional Development Units. This course is recognized by ECSA South Africa (ref. INCOSE 19/002) for CPD 2 points. This course may qualify for CPD, CLP and similar purposes with other organizations (16 instructor hours).

Key Learning Objectives

At the conclusion of this course, delegates are expected to:

  • understand the overall concepts which are characteristic of a systems approach to design;
  • understand the overall process elements, and their relationships, which collectively constitute the process building blocks of design (verb);
  • learn a structured approach to physical design, use logical solution to help get physical design right, evaluate solution alternatives (conduct trade-off studies) and optimize design in a structured way;
  • learn in overview about the disciplines of reliability engineering, safety engineering, maintainability engineering and producibility (manufacturability) engineering;
  • have some basic capability to tailor the application of design principles and methods to different application scenarios; and
  • be capable of extensive further learning in the field, within a sound conceptual framework.

Training Method and Materials

The course makes extensive use of workshops to put into practice the techniques covered in theory sessions.

The course is delivered using a mixture of formal presentation, informal discussion, and extensive workshops which exercise key aspects of a systems approach to design, using a single system throughout. The result is a high degree of learning, as evidenced by workshop work products, and the extensive commendations received from delegates.

Delegates will be provided with:

  • comprehensive course materials containing presentation material and supporting reading material;
  • a Workbook containing workshop exercises, with worked examples also distributed;
  • numerous supplementary descriptions, checklists, forms and charts which you can put to use immediately; and
  • complimentary access to PPI's evolving Systems Engineering Goldmine.
