Getting to know your unit Engineering processes, whether concerned with the manufacture of a product or the delivery of an engineering service, are the cornerstones of all modern industrial engineering. A single individual cannot carry out any complex industrial function effectively – often the coordinated efforts of hundreds or even thousands of people are required to manufacture a complex product such as a car or an aeroplane. This unit covers a range of practical and teamworking skills that are necessary when manufacturing a product or delivering a service safely as a team. How you will be assessed This unit will be assessed by a series of internally assessed tasks set by your tutor. Throughout this unit you will find assessment practice activities to help you work towards your assessment. Completing these activities will not mean that you have achieved a particular grade, but you will have carried out useful research or preparation that will be relevant when it comes to your final assignment. In order for you to achieve the tasks in your assignment, it is important to check that you have met all of the assessment criteria. You can do this as you work your way through each assignment. If you are hoping to gain a Merit or Distinction grade, you should also make sure that you present the information in your assignments in the style that is required by the relevant assessment criterion. For example, Merit criteria require you to analyse, and Distinction criteria require you to evaluate. The assignments set by your tutor will consist of a number of tasks designed to meet the criteria in the table. They are likely to take the form of written reports, but may also include activities such as the following: ▸ Reviewing and analysing case studies based on the manufacture of an engineered product or delivery of a service in terms of the processes used and the influence of human factors. ▸ Creating engineering drawings using computer-aided design (CAD) software. ▸ Carrying out practical engineering processes both as a team leader and as a member of a team.

Pass Merit Distinction Learning aim A Examine common engineering processes to create products or deliver services safely and effectively as a team A.D1 Evaluate, using high quality written language, the effectiveness of using different engineering processes to manufacture a product or to deliver a service and how human factors, as an individual and as a team, affect the performance of engineering processes. Assessment practice 2.1 A.P1 Explain how three engineering processes are used safely when manufacturing a given product or when delivering a given service. Assessment practice 2.1 A.M1 Analyse why three engineering processes are used to manufacture a product or to deliver a service and how human factors, as an individual and as a team, affect the performance of engineering processes. Assessment practice 2.1 A.P2 Explain how human factors, as an individual or as a team, affect the performance of engineering processes. Assessment practice 2.1 Learning aim B Develop two-dimensional computer-aided drawings that can be used in engineering processes B.D2 Refine, using layers, an accurate orthographic projection of a component containing at least three different types of common feature and a circuit diagram containing at least six different component types to an international standard. Assessment practice 2.2 B.P3 Create an orthographic projection of a given component containing at least three different types of feature. Assessment practice 2.2 B.M2 Produce, using layers, an accurate orthographic projection of a component containing at least three different types of feature and a circuit diagram containing at least six different component types that mainly meet an international standard. Assessment practice 2.2 B.P4 Create a diagram of a given electrical circuit containing at least six different component types. Assessment practice 2.2 Learning aim C Carry out engineering processes safely to manufacture a product or to deliver a service effectively as a team C.P5 Manage own contributions to set up and organise a team in order to manufacture a product or deliver a service. Assessment practice 2.3 C.M3 Manage own contributions safely and effectively using feedback from peers, as a team member and a team leader, to manufacture a product or to deliver a service. Assessment practice 2.3 C.D3 Consistently manage own contributions effectively using feedback from peers, as a team member and a team leader, to set up, organise and manufacture a product or deliver a service safely, demonstrating forward thinking, adaptability or initiative. Assessment practice 2.3 C.P6 Produce, as an individual team member, a risk assessment of at least one engineering process. Assessment practice 2.3 C.P7 Set up, as an individual team member, at least one process safely by interpreting technical documentation. Assessment practice 2.3 C.P8 Manage own contributions safely, as a team member and a team leader, to manufacture a batch of an engineered product or to deliver a batch of an engineering service. Assessment practice 2.3 76 Delivery of Engineering Processes Safely as a Team These ideas must be developed, evaluated and refined to achieve a viable solution. Once a solution is established, it must be communicated effectively to the people who will be asked to manufacture the product or deliver the service. Preparation will include these documents: ▸ Technical specifications – define exactly what a product or service will do. ▸ Engineering drawings – define exactly what the individual components of a product will look like and how they should be assembled during manufacture to make the final product. ▸ Scale of production – defines the number of products that need to be manufactured or the number of times a service needs to be performed, hence dictating the approach to manufacture or service delivery; (see Table 2.1). ▸ Work plans – define a standard methodology that should be followed when manufacturing a product or delivering a service. ▸ Quality control documents – define the checks that should take place both during and after manufacturing a product or delivering a service. ▸ Table 2.1 Characteristics of different scales of production One-off Small batch Mass or large batch Continuous Unit cost high medium low low Tools and equipment general specialised specialised and dedicated dedicated Initial investment low medium high high Production efficiency low medium high very high Labour type skilled skilled and semi-skilled semi-skilled and unskilled unskilled Labour cost high medium low low Engineering projects are usually large and complex, requiring a range of specialist skills to complete. Some of the great feats of engineering from history, such as Concorde or the Channel Tunnel, involved tens of thousands of people working together over decades to bring the project to fruition. The manufacture of everything, from condensing boilers to cars, depends on multi-skilled teams of engineers and technicians working together to manufacture products quickly, efficiently and in the necessary numbers to satisfy demand. After manufacture, similar multi-skilled teams are relied upon to deliver the services that help to maintain and repair these complex products. A1 Common engineering processes Preparation before product manufacture or product delivery Generally engineering products or services start life as ideas on how to solve a particular problem or satisfy some other demand from a customer or the wider marketplace. Key terms Team – a group containing three or more individuals who have a common objective or shared goal. Batch – three or more products manufactured or services delivered together.
