No new topics of a technical are introduced into this unit. The unit requires the students to integrate their skills and knowledge from earlier units into a single, design project executed in a team environment. The content therefore includes:

• A feasibility study which includes marketing analysis, plant location and health and safey assessment and preliminary economic evaluation of the proposal
• A process development report which includes the assessment of technology options to produce the required product, a mass and energy balance of the proposed process, as evaluation of the environmental impact of the process, a safety analysis, and a detailed process flow diagram of the proposed process
• A detailed design report including the detailed process and mechanical design of a unit operation with the process, the full process control and operation as well as process and instrumentation diagram of the process, specification of all minor equipment items in the process, a full HAZOP of a section of the plant, a full economic analysis and sensitivity study of the proposed plant

This subject has been integrated with the Skills Towards Employment Program (STEP) and contains activities that can assist in the completion of the Engineering Practice Hurdle (EPH).

AIMS

This subject emphasises the critical nature of Operations Management as an essential part of a competent engineer’s portfolio of knowledge and skills.

INDICATIVE CONTENT

Topics include:

• Clarifying how the core concepts of operations management (including both processes and projects) help organisations achieve sustainable competitive advantage
• Managing the integration of technology, people, functions and operating systems to support the complex processes underlying the development and manufacture of products and the creation and delivery of services
• How organisations develop their core processes and project management capabilities and manage through them and how new technologies alter their design and performance. Relevant issues include process ownership, project management skills, teamwork, stakeholder management and communication, performance measurement and change management concepts.

AIMS

In this subject students will learn how to structure and work with engineering contracts to deliver and procure engineering outcomes. Students will develop a working knowledge of contract administration and gain an understanding of commercial out workings of engineering. All engineers interface commercially with engineering contracts throughout their careers and thus the application of the subject content is broad. Those seeking to work as a contractor and as a contract administrator will find direct application of this subject’s content.

INDICATIVE CONTENT

Commercial management of engineering projects including the role and responsibilities of corporate managers, market analysis, structuring of procurement options, development of contractual terms and conditions, and the pricing of work.

Estimating and tendering engineering works via work breakdown structures, work method statements, risk identification and tendering principles. Contract administration and project control functions and techniques including time and money negotiations and cash flow management are also covered through the use of detailed case study material.

AIMS

This subject examines the structure and basic building blocks of high performing organisations from a senior management perspective. It covers tools and techniques to conduct both an analysis of the external environment and the strategies to align the appropriate internal skills and capabilities.

INDICATIVE CONTENT

The subject includes:

• The role of leadership in strategy formulation and its balance with execution
• Overcoming the barriers to implementation of strategic plans
• Business integration and managing technology
• Entrepreneurship in modern business.
