A

production schedule

77
Q

this specifies the types and
quantities of the raw material (RM) and subassemblies used in producing a single unit of finished product. The RM requirements for an entire batch are determined by multiplying the ___________ by the number

80
Q

The _______________ draws from BOMs and route sheets to specify the materials and
production (machining, assembly, and so on) for each batch. These, together with move tickets, initiate the manufacturing process in the production departments.

Q

this records work done in each work center and authorizes the movement of the job or batch from one work center to the next.

Q

We first examine the production planning and control function. This consists of two main activities:

A

(1) specifying materials and operations requirements
and (2) production scheduling.

Q

The actual production operations begin when workers
obtain raw materials from ________________ in exchange for materials requisitions.

A

storekeeping

86
Q

TORF: Upon receipt of the last move ticket, the open work order
file is opened.

A

False. closed

87
Q

The inventory control function consists of three main activities:

A
  1. it provides production planning and control with status reports on finished goods and raw materials inventory.
  2. , the inventory control function is continually involved in updating the raw material inventory records from materials requisitions, excess materials requisitions, and materials return tickets.
  3. upon receipt of the work order from the last work center, inventory control records the completed
    production by updating the finished goods inventory records
88
Q

TORF: An objective of inventory control is to minimize total inventory cost while ensuring that surplus
inventories exist to meet current demand.

A

False. adequate inventories

89
Q

A commonly used inventory model is the _________________

A

economic order quantity (EOQ) model

Q

The objective of the EOQ model is to

A

91
Q

_________________ of the conversion cycle record the financial effects of the physical events that
are occurring in the production process.

A

Cost accounting activities

92
Q

TORF: In the traditional manufacturing environment, production planning and control authorize the production activity via a formal work order. This document reflects production requirements, which are the
difference between the expected demand for products (based on the sales forecast) and the FG inventory on hand.

A

TRUE

93
Q

TORF: Move tickets signed by the employee in each work center authorize activities for each batch and for
the movement of products through the various work centers.

A

False. only supervisors have authorization in signing move tickets

94
Q

TORF: Materials requisitions and excess materials requisitions authorize the storekeeper to store materials to the work centers

A

False. release materials

95
Q

TORF: The production planning and control department is organizationally together
from the work centers

A

False. segregated

96
Q

TORF: Another control objective is to segregate record keeping from asset custody

A

TRUE

97
Q

TORF: The supervisors in the work centers oversee the usage of RM in the production process. This helps
to ensure that all materials released from stores are used in production and that waste is minimized.
Employee time cards and job tickets must also be checked for accuracy

A

TRUE

Q

TORF: The HR department also observe and review timekeeping activities. This promotes accurate employee time cards and job tickets.

A

False. Supervisors

warehouses. Control methods used include identification badges, security guards, observation devices, and various electronic sensors and alarms.

A

TRUE

100
Q

TORF: The use of actual costs provides a type of access control. By specifying the quantities of material
and labor authorized for each product, the firm limits unauthorized access to those resources. To
obtain excess quantities requires special authorization and formal documentation

A

False. standard costs

101
Q

A method of control that
also supports an audit trail is the use of ____________________

A

tickets with the prescribed standards.

A

TRUE

Q

TORF: The FG department also fulfills an important verification function by checking the total movement of products from WIP to FG. This is done by reconciling journal vouchers from cost accounting and
summaries of the inventory subsidiary ledger from inventory control

A

104
Q

TORF: internal and external auditors periodically verify the RM and FG inventories on hand through
an estimate count. They compare actual quantities against the inventory records and make adjustments
to the records when necessary

A

False. physical count
