Questions to be addressed in this chapter include:

     What are the basic business activities in which an organization engages?

     What decisions must be made to undertake these activities?

     What information is required to make those decisions?

     What role does the data processing cycle play in organizing business activities and

    providing information to users?

     What is the role of the information system and enterprise resource planning in modern



     Businesses engage in a variety of activities, including acquiring capital, buying buildings and

    equipment, hiring and training employees, purchasing inventory, doing advertising and marketing,

    selling goods or services, collecting payment from customers, paying employees, paying taxes,

    and paying vendors. Each decision requires different types of information.

     Information needed for decisions may be financial or non-financial and may come from either

    internal or external sources. An effective AIS needs to be able to integrate this information.


     The AIS interacts with external parties, such as customers, vendors, creditors, and governmental

    agencies. The AIS also interacts with internal parties such as employees and management. These

    interactions are typically two-way, in that the AIS sends information to and receives information

    from these parties.


     A transaction is an agreement between two entities to exchange goods or services OR any other

    event that can be measured in economic terms by an organization. EXAMPLES: Sell goods to

    customers; depreciate equipment.

     The transaction cycle is a process that begins with capturing data about a transaction and ends

    with an information output, such as a set of financial statements.

     Many business activities are paired in give-get exchanges

     The basic exchanges can be grouped into five major transaction cycles.

     Revenue cycleInteractions with customers. Give goods; get cash.

     Expenditure cycleInteractions with suppliers. Give cash; get goods.

     Production cycleGive labor and raw materials; get finished product.

     Human resources/payroll cycleGive cash; get labor.

     Financing cycleGive cash; get cash.

     Thousands of transactions can occur within any of these cycles, but there are relatively few types

    of transactions in a cycle.

     Every transaction cycle relates to other cycles and interfaces with the general ledger and reporting

    system, which generates information for management and external parties.

    Chapter 2: Business Processes 1

     The revenue cycle gets finished goods from the production cycle; provides funds to the financing

    cycle; and provides data to the general ledger and reporting system.

     The expenditure cycle gets funds from the financing cycle; provides raw materials to the

    production cycle; and provides data to the general ledger and reporting system. The production cycle gets raw materials from the expenditure cycle; gets labor from the

    HR/payroll cycle; provides finished goods to the revenue cycle; and provides data to the general

    ledger and reporting system.

     The HR/payroll cycle gets funds from the financing cycle; provides labor to the production cycle;

    and provides data to the general ledger and reporting system.

     The financing cycle gets funds from the revenue cycle; provides funds to the expenditure and

    HR/payroll cycles; and provides data to the general ledger and reporting system. The general ledger and reporting system gets data from all of the cycles and provides information

    for internal and external users.

     Many accounting software packages implement the different transaction cycles as separate

    modules. Not every module is needed in every organization, e.g., retail companies don’t have a

    production cycle. Some companies may need extra modules. So the implementation of each

    transaction cycle can differ significantly across companies.

     However the cycles are implemented, it is critical that the AIS be able to accommodate the

    information needs of managers and integrate financial and non-financial data.


     Accountants play an important role in data processing. They answer questions such as: What

    data should be entered and stored? Who should be able to access the data? How should the data

    be organized, updated, stored, accessed, and retrieved? How can scheduled and unanticipated

    information needs be met? To answer these questions, they must understand data processing


     An important function of the AIS is to efficiently and effectively process the data about a

    company’s transactions. In manual systems, data is entered into paper journals and ledgers. In

    computer-based systems, the series of operations performed on data is referred to as the data

    processing cycle.

     The data processing cycle consists of four steps: (1) data input; (2) data storage; (3) data

    processing; and (4) information output.


     The first step in data processing is to capture the data. This capture is usually triggered by a

    business activity. Data is captured about: the event that occurred; the resources affected by the

    event; and the agents who participated.

     A number of actions can be taken to improve the accuracy and efficiency of data input:

     Turnaround documents

     Source data automation

     Well-designed source documents and data entry screens

     Using pre-numbered documents or having the system automatically assign sequential

    numbers to transactions

     Verifying transactions.

    2 Chapter 2: Business Processes


Data needs to be organized for easy and efficient access. Let’s start with some vocabulary terms

    with respect to data storage.

     A ledger is a file used to store cumulative information about resources and agents. We typically

    use the word ledger to describe the set of t-accounts. The t-account is where we keep track of the

    beginning balance, increases, decreases, and ending balance for each asset, liability, owners’

    equity, revenue, expense, gain, loss, and dividend account.

     The general ledger is the summary level information for all accounts. Detail information is not

    kept in general ledger accounts.

     The subsidiary ledgers contain the detail accounts associated with the related general ledger

    account. The related general ledger account is often called a control account. The sum of the

    subsidiary account balances should equal the balance in the control account. Coding is a method of systematically assigning numbers or letters to data items to help classify

    and organize them. There are many types of codes, including sequence codes, block codes, and

    group codes

     With sequence codes, items such as checks or invoices are numbered consecutively to ensure no

    gaps in the sequence. The numbering helps ensure that all items are accounted for and that there

    are no duplicate numbers (which would suggest errors or fraud).

     When block codes are used, blocks of numbers within a numerical sequence are reserved for a

    particular category.

     When group codes are used, two or more subgroups of digits are used to code an item. Group

    coding schemes are often used in assigning general ledger account numbers. The following

    guidelines should be observed:

     The code should be consistent with its intended use, so make sure you know what users


     Provide enough digits to allow room for growth.

     Keep it simple in order to minimize costs, facilitate memorization, and ensure employee


     Make sure it’s consistent with the company’s organization structure and other divisions

    of the organization.

     The chart of accounts is a list of all general ledger accounts an organization uses. Group coding

    is often used for these numbers, e.g.:

     The first section identifies the major account categories, such as asset, liability, revenue,


     The second section identifies the primary sub-account, such as current asset or long-term


     The third section identifies the specific account, such as accounts receivable or inventory.

     The fourth section identifies the subsidiary account, e.g., the specific customer code for

    an account receivable.

     The structure of the chart of accounts is an important AIS issue, as it must contain sufficient

    detail to meet the organization’s needs.

     In manual systems and some accounting packages, the first place that transactions are entered is

    the journal.

     A general journal is used to record non-routine transactions, such as loan payments; summaries

    of routine transactions; adjusting entries; and closing entries.

     A special journal is used to record routine transactions. The most common special journals are

    cash receipts, cash disbursements, credit sales, and credit purchases.

     An audit trail exists when there is sufficient documentation to allow the tracing of a transaction

    from beginning to end or from the end back to the beginning. The inclusion of posting references

    and document numbers enable the tracing of transactions through the journals and ledgers and

    therefore facilitate the audit trail.

    Chapter 2: Business Processes 3

     When transaction data is captured on a source document, the next step is to record the data in a

    journal. A journal entry is made for each transaction showing the accounts and amounts to be

    debited and credited.

     When routine transactions occur, they are initially recorded in special journals (e.g., cash

    receipts, cash disbursements, credit sales, credit purchases). When non-routine transactions

    occur, they are recorded in the general journal.

     Periodically, the transactions in the special journal are totaled, and a summary entry is made in

    the general journal. The individual line items in the special journal are posted to the subsidiary

    ledger accounts, and the items in the general journal are posted to the general ledger. Periodically, the balances in the general ledger control accounts are compared to the sums of the

    balances in the related subsidiary accounts.


     Following are some computer-based storage concepts that should be understood:

     Entitysomething about which information is stored. Example: Students are an entity

    in the university.

     Attribute—characteristics of interest with respect to the entity. A student’s GPA is an

    attribute of a student.

     Fieldthe physical space where an attribute is stored.

     Recordthe set of attributes stored for a particular instance of an entity, e.g., all the

    information stored about student John Doe is John Doe’s record.

     Data Valuethe intersection of the row and column, i.e., a particular field for a

    particular record.

     Filea group of related records.

     Master File—a file that stores cumulative information about an organization’s entities.

    Conceptually similar to a ledger in that (1) the file is permanent; (2) it exists across fiscal

    periods; and (3) changes are made to the file to reflect effects of new transactions.

     Transaction Filea file that contains records of individual transactions (events) during a

    fiscal period. Similar to a journal in that the files are temporary and maintained for one


     Databasea set of inter-related, centrally coordinated files.


     Once data about a business activity has been collected and entered into a system, it must be


     There are four different types of file processing:

     Updating data to record the occurrence of an event, the resources affected by the event,

    and the agents who participated, e.g., recording a sale to a customer.

     Changing data, e.g., a customer address.

     Adding data, e.g., a new customer.

     Deleting data, e.g., removing an old customer that has not purchased anything in 5 years. Updating can be done through several approaches:

     Batch Processing--Source documents are grouped into batches, and control totals are

    calculated. Periodically, the batches are entered into the computer system, edited, sorted,

    and stored in a temporary file. The temporary transaction file is run against the master

    file to update the master file. Output is printed or displayed, along with error reports,

    transaction reports, and control totals.

     Online Batch Processing--Transactions are entered into a computer system as they occur

    and stored in a temporary file. Periodically, the temporary transaction file is run against

    the master file to update the master file. The output is printed or displayed.

    4 Chapter 2: Business Processes

     Online, Real-time Processing--Transactions are entered into a computer system as they

    occur. The master file is immediately updated with the data from the transaction. Output

    is printed or displayed.


The final step in the information process is information output.

     This output can be in the form of:

     Documents--Records of transactions or other company data, such as paychecks or

    purchase orders. Documents generated at the end of the transaction processing activities

    are known as operational documents (as opposed to source documents). They can be

    printed or stored as electronic images.

     Reports--Used by employees to control operational activities and by managers to make

    decisions and design strategies. They may be produced on a regular basis, on an

    exception basis, or on demand. Organizations should periodically reassess whether each

    report is needed.

     Queries--User requests for specific pieces of information. They may be requested

    periodically or one time and can be displayed on the monitor (soft copy) or on paper

    (hard copy).

     Output can serve a variety of purposes:

     Financial statements can be provided to both external and internal parties.

     Some outputs are specifically for internal use:

     For planning purposes, such as budgets and sales forecasts.

     For management of day-to-day operations, e.g., delivery schedules.

     For control purposes, such as performance reports.

     For evaluation purposes, such as employee error rates.

     With managerial reports, you get what you measure. If you’re not very careful about what you

    measure, there can be dysfunctional results, such as managers foregoing needed equipment

    maintenance to stay within a budget.


     The traditional AIS captured financial data. Non-financial data was captured in other,

    sometimes-redundant systems.

     Enterprise resource planning (ERP) systems are designed to integrate all aspects of a company’s

    operations (including both financial and non-financial information) with the traditional functions

    of an AIS.


     The basic business activities in which an organization engages, the decisions that need to be made,

    and the information required to make those decisions.

     The data processing cycle and its role in organizing business activities and providing information

    to users.

     The role of information systems in modern organizations and the notion of enterprise resource

    planning systems.

     Problems 2.1 and 2.2 provide useful experience with charts of accounts.

     Problem 2.9 provides a good workout on understanding the different business cycles.

     Problem 2.10 helps students internalize the distinction between master and transaction files.

     The following crossword can be used to help students assimilate vocabulary terms.
















    1 The cycle that involves interactions with customers.

    4 The cycle that involves transforming labor and materials into a finished product. 5 Physical space where an attribute is stored.

    6 An agreement between two entities to exchange goods or services or any event that can be

    measured in economic terms by an organization.
