1 Answers to examination-style question 1 a) What are the three main types of production system? (3 marks) The three main types of production system are: mass, batch and one-off. b) Explain in detail why it is important to plan for production. (3 marks) It is important to plan for production because workers need to work together efficiently to make products. Resources need to be organised and work schedules need to be worked out to meet production deadlines. The order of making needs to be logical and quality assurance included so that a quality product is made. c) During production some parts of products might be made as a sub-assembly. Explain what is meant by a sub-assembly. (3 marks) Sub-assembly is used when it is necessary to attach small components to sections, or to join smaller parts together first, before working to build the main product. d) Explain what is meant by just-in-time stock control (JIT). (2 marks) JIT stock control is a cost-effective way of ordering materials, components and subassemblies to arrive just before they are needed. This reduces stock storage time and costs.

5 f) i) What is a manufacturing specification? (3 marks) A manufacturing specification is a document that describes the stages of manufacture and the materials needed in order to make the product. ii) Give 6 pieces of information that could be included on a manufacturing specification. A manufacturing specification may include: a flowchart, samples of fabrics, a working drawing, care instruction label, product description and code, stitch details. 2 a) Name two different fastenings used on textile products. Use notes and diagrams to explain how to add these fastenings to the fabric. Include information about materials and equipment that will be needed. Velcro - Pin Velcro on to fabric in correct position. - Machine stitch along lines. - Repeat for both parts of Velcro. - Materials and equipment needed for adding Velcro fastenings are: Velcro, pins. Magnetic fastening Magnet Metal fastening to clip together with You need to buy a kit that includes the fastening, instructions for inserting and a tool to help you add the fastening to the fabric.

6 b) Many textile products include pockets. Explain one method of constructing a pocket and of attaching it to a wall hanging. Use notes and diagrams to show how this could be done stepby-step. Use the information given on page in the Student Book on how to make a simple patch pocket. c) i) List three different ways to neaten a flat seam. (3 marks) Three different ways to neaten a flat seam are: cut a raw edge using pinking shears, overlock or zig-zag stitch raw edges, bind edges with bias binding. ii) Use notes and diagrams to explain one method of neatening a flat seam. Include information about materials and equipment that will be needed. Use the information given on page 106 in the Student Book on how to make a flat seam. Tool for neatening a seam: pinking shears. d) List 3 different hand tools for cutting. (3 marks) Choose from: craft knife, seam ripper, embroidery scissors, fabric scissors, pinking shears. e) A dart is often made in textile products. What is a dart? (2 marks) A dart is a pointed pleat of fabric which is stitched into fabric pieces to create a 3-D shape. f) Use notes and diagrams to show how a dart could be put into a piece of fabric. Use the information given on page 108 in the Student Book on how to make a dart. g) Use notes and diagrams to explain one method of inserting a zip. Include information about materials and equipment that will be needed. Use the information given on page 111 in the Student Book on stitching a zip in place. Materials and equipment for inserting a zip include: zip, pins, needle, thread, zip foot on sewing machine. h) Use notes and diagrams to explain one method of making a button hole.

7 3 a) Explain how ICT can be used to research, collect, sort and present information. (2 marks) ICT can be used to carry out primary research, for example using a digital camera to record inspiration and information from looking at a design theme or at existing products. Questionnaires can be written and sent, and the data collected can be analysed and presented using ICT. The internet can be searched to collect secondary research. CD-ROMs can be used to store information. Data can be presented using spreadsheets and graphs. Slideshow presentations can be designed to show researched information. b) Computers can be used by designers to help them design and present ideas. Give two advantages when using them to draw fashion designs. (2 marks) ICT can speed up designing and be used to show a wide range of alternative ideas for styles, patterns and colours. Improvements can be made quickly and clients can work with designers more closely to suggest modifications. Presentations can be built using existing images in a variety of ways for promotional leaflets, posters, invitations to fashion shows, presentation boards, etc. c) List three ways that computers can be used in textile manufacturing and explain how their use benefits production. i) Pattern lay plans can be worked out using ICT to quickly arrange the pattern pieces with the most efficient use of fabric. This saves fabric costs. ii) Digital printing of fabric allows for a wide range of colours and detailed patterns to be printed. Designs can be modified quickly and with little cost, compared to making up new screens for screen printing. iii) Automatic spreading of fabric and cutting out fabric pieces. Done manually, this involves lifting heavy fabric rolls and using sharp blades, so using computers to move fabric and control cutting makes this a safer process.
