Chapter 7 The Conversion Cycle
The Continuum of Manufacturing Practices
The Conversion Cycle • The conversion cycle transforms input resources, raw materials, labor, and overhead into finished products or services for sale. • The conversion cycle consists of two subsystems: – the production system – the cost accounting system
Production System • Involves the planning, scheduling, and control of the physical product through the manufacturing process – determining raw materials requirements – authorizing the release of raw materials into production – authorizing work to be conducted in the production process – directing the movement of work through the various stages of production
Production Methods • Continuous Processing creates a homogeneous product through a continuous series of standard procedures. • Batch Processing produces discrete groups (batches) of products. Each item in the batch is similar. • Make-to-Order Processing involves the fabrication of discrete products in accordance with customer specifications.
Documents in the Batch Production System • Sales Forecast - expected demand for the finished goods • Production Schedule - production plan and authorization to produce • Bill of Materials (BOM) - specifies the types and quantities of the raw materials and subassemblies used to produce a single finished good unit
Documents in the Batch Production System • Route Sheet - details the production path a particular batch will take in the manufacturing process – sequence of operations – time allotted at each station • Work Order - uses information from the BOM and route sheet to specify the exact materials and production processes for each batch
Documents in the Batch Production System • Move Ticket - records work done in each work center and authorizes the movement of the batch • Materials Requisition - authorizes the inventory warehouse to release raw materials for use in the production process
Cost Accounting System • Records the financial effects of the events occurring in the production process • Initiated by the work order • Cost accounting clerk creates a new cost record for the new batch and files in WIP file • The records are updated as materials and labor are used
Elements of the Cost Accounting System Inventory Control Work Centers materials requisitions job tickets completed move tickets COST ACCOUNTANTS STANDARDS Update WIP accounts DL DM Mfg. OH. Compute Variances
Summary of Internal Controls
Internal Controls • Transaction authorizations – work orders reflect a legitimate need based upon sales forecast and the finished goods on hand – move tickets (with authorized signature from each work station) authorize the movement of the batch through the various work centers – materials requisitions authorize the warehouse to release materials to the work centers
Internal Controls • Segregation of duties – production planning and control department is separate from the work centers – inventory control separate from materials storeroom and finished goods warehouse – cost accounting function accounts for WIP and should be separate from the work centers in the production process
Internal Controls • Supervision – supervisors in the work centers oversee the usage of raw materials in the production process to ensure that all released materials are used in production and waste is minimized – employee time cards and job tickets are checked for accuracy
Internal Controls • Access control – direct access to assets • storerooms, production work centers, and finished goods warehouses • quantities in excess of standard amounts should require approval – indirect access to assets • materials requisitions, excess materials requisitions, and employee time cards
Internal Controls • Accounting records – pre-numbered documents – work orders – cost sheets – move tickets – job tickets – material requisitions – WIP and FGs files
Internal Controls • Independent verification – cost accounting reconciles material usage (material requisitions) and labor usage (job tickets) with prescribed standards, and variances are investigated – GL dept. verifies the total movement from WIP to FG by reconciling journal vouchers from cost accounting and inventory subsidiary ledger summaries from inventory control – internal and external auditors periodically verify the raw materials and FGs inventories on hand through a physical count
The World-Class Environment and Manufacturing Flexibility • Customers: – want quality products – want them quickly – want variety • Achieving manufacturing flexibility incorporates four operational characteristics: – – physical reorganization of the production facilities automation of the manufacturing process reduction of inventories high product quality
Progression of Automation in the Manufacturing Process Traditional Islands of Technology Process Simplification (JIT) Computer Integrated Manufacturing Progression of Automation toward World-Class Status
Automating Manufacturing
Automating Manufacturing • Process Simplification: – reduces the complexity of the physical layout – groups of CNC machines are arranged in cells to produce an entire part from start to finish – no human involvement in a cell • Computer Integrated Manufacturing (CIM): – a completely automated environment which employs automated storage and retrieval systems (AS/RS) and robotics
Automating Manufacturing • Robotics: – use special CNC machines that are useful in performing hazardous, difficult, and monotonous tasks • Computer-Aided Design (CAD): – increases engineers’ productivity – improves accuracy – allows firms to be more responsive to market demands – interfaces with CAM and MRPII systems
Automating Manufacturing • Computer Aided Manufacturing (CAM): – uses computers to control the physical manufacturing process – provides greater precision, speed, and control than human production processes • Manufacturing Resources Planning (MRP II): – an extension of materials requirements planning (MRP) – more than inventory management--it is a system for coordinating the activities of the entire firm
Automating Manufacturing • Enterprise Resource Planning (ERP) Systems: – huge commercial software packages that support the information needs of the entire organization, not just the manufacturing functions – automates all business functions along with full financial and managerial reporting capability • Electronic Data Interchange (EDI): – external communications with its customers and suppliers via Internet or direct connection
Accounting and MRP
How can inventories be reduced? • Just-in time (JIT) manufacturing is a model that fosters inventories reduction and even elimination. It is based on the following assumptions: – zero defects – zero setup time – small lot sizes – zero inventories – zero lead times and reliable vendors – team attitude
What’s Wrong with Traditional Cost Accounting Information? • • Inaccurate cost allocations Time lag in reporting Financial orientation Emphasis on standard costs
Allocation of Costs Using ABC
The World-Class Information System… • is the integration of all the system’s functional and technological components: – basic accounting applications – ABC – materials requirements planning – capacity planning – inventory control – bill-of-materials – master productions schedule – forecasting – order entry – computer-aided design – computer-aided manufacturing – EDI communications links
Control Issues in the WCIS • Paperless environment - no traditional audit trail • Automatic transactions - need assurance that: – the system places orders only when inventory is needed – inventory orders are placed only with approved vendors – the quantity of items ordered is correct for the needs of the organization – programmed procedures matching electronic controls data before initiating payment perform correctly • Networking considerations
