Question

Using a structure chart, represent the procedural structure of a simple inventory/accounting system for a small store (perhaps a privately owned curio shop in a resort community). What modules in your system must be modified because of changes in sales tax laws? What modules would need to be changed if the decision is made to maintain a record of past customers so that advertising can be mailed to them?

Short answer

Modify Tax Calculation for tax law changes; Customer Management for advertising actions.

Step-by-step solution

Understand the Components of the Inventory/Accounting System

To create a structure chart, first understand the components needed for the system. Key components may include inventory management, sales processing, customer management, and reporting functions. Each component handles specific tasks important to the overall operation of the store.

Identify Modules and Their Functions

Divide the system into modules. For example, the system may have an "Inventory Update" module that manages stock levels, a "Sales Processing" module that handles transactions, a "Customer Management" module for keeping customer records, and a "Tax Calculation" module to apply tax laws. Thoroughly understand what each module does.

Design the Structure Chart

Create a visual representation of the system layout with a structure chart. The chart should show the hierarchy and interaction between modules. Typically, you would place the main system at the top, with branches connecting to sub-modules like inventory, tax calculations, and customer management.

Determine Impact of Sales Tax Law Changes

Identify which modules are affected by sales tax law changes. The "Tax Calculation" module is the primary component needing modification. Any changes in tax rates or rules directly affect how this module calculates the costs in transactions.

Assessing Customer Record Module Changes

Consider the addition of a customer record system for marketing purposes. The "Customer Management" module would need changes to store historical data and utilize it for advertising. This may involve expanding its data storage capabilities and incorporating functions to extract information for marketing campaigns.

Key concepts

Inventory Management

Inventory management is a critical component of any retail system, such as the scenario described with a curio shop in a resort community. It involves overseeing and controlling the ordering, storage, and use of products to ensure optimal stock levels are maintained.
Effective inventory management prevents loss, minimizes costs, and ensures that products are always available to meet customer demand. In our structure chart, an "Inventory Update" module would govern these tasks.
Key responsibilities of this module include:

• Keeping track of stock levels and updates when sales are processed.
• Ensuring reorders are placed when inventory falls below a certain threshold.
• Managing product deliveries and inventory-related discrepancies.

For a small shop, balancing inventory levels is crucial to avoid overstocking or stockouts, both of which can negatively impact profitability and customer satisfaction.

Sales Processing

Sales processing in a retail environment is the point at which customer transactions are handled. This module is essential, as it directly interfaces with both the inventory and financial systems of the store.
In the context of our structure chart, the "Sales Processing" module captures data at the time of sale, updating inventory levels and providing information required for financial reporting.
Key tasks performed by the sales processing module include:

• Processing customer purchases and updating the corresponding inventory.
• Calculating total sales, including any applicable discounts or promotions.
• Ensuring transaction data is accurately recorded and processed.

This system aspect ensures seamless transactions and is pivotal for both customer satisfaction and accurate bookkeeping.

Customer Management

Customer management refers to the strategies and technologies used to manage interactions and data associated with current and potential customers. In a small retail setting, maintaining strong customer relationships can significantly drive repeat business.
For our structure chart, the "Customer Management" module keeps a database of customer information. This includes contact details, purchase history, and possibly preferences.
This module must be adaptable to support additional functions like:

• Storing extended customer data for marketing and communication purposes.
• Tracking customer interactions and feedback.
• Identifying sales patterns to offer personalized promotions.

By effectively managing customer data, a shop can personalize marketing and enhance customer service, improving customer retention and satisfaction.

Tax Calculation

Tax calculation is essential to comply with local and national regulations. It adjusts the total cost of transactions according to current tax laws, ensuring the correct amount of tax is added to customer purchases.
In the described system, the "Tax Calculation" module is responsible for applying the correct tax rates during sales processing. This module needs regular updates to stay aligned with changing tax laws.
Core functionalities of this module include:

• Applying applicable sales tax rates to transactions accurately.
• Updating calculations based on updated tax laws or rates.
• Ensuring all sales reports reflect taxes appropriately for auditing and reporting purposes.

By incorporating an adaptable tax calculation system, the store remains compliant and avoids potential legal issues related to incorrect tax reporting.
