Explain operations management’s role in business

Operations management plays a crucial role in business. Operations management consists of a scope ranging across firms and includes interrelated activities e.g. forecasting, scheduling, assuring quality, motivating employees. Operations management also plays a significant role in business as it ensures the business forecasts, conducts capacity planning (estimating number of g/s that can be produced), appropriately creates schedules, manages inventory, assures quality, motivates and trains employees and locates facilities.

Describe the correlation between operations management and information technology

IT plays a significant role in operations management. This can be displayed as management employs the use of IT to make operations management decisions regarding various issues related to productivity, costs, flexibility, quality and customer satisfaction. IT is used when making operation management decisions as most OM decisions involve many alternatives, thus OM information systems are essential for mgrs to make well informed decisions. Decision support systems and executive information systems driven by IT can also be used to help management perform a what-if analysis, sensitivity analysis, drill-down and consolidation. IT has a strong correlation with operations management in that it enables operation managers attain visibility across the firms processes and analyse the following:

- what resources will be needed

- when resources will be needed (use of JIT mechanism and reports [error rates])

- where the processes will be performed e.g. political, social, cultural, economical influences

- how well the firm structure their resource

and

- who will perform the work

Q: How does IT assist with OM and SCM?

IT acts as a bridge for effective operations management:

Explain supply chain management and its role in business

Supply chain management involves the management of information flows between stages in a firms supply chain. This is performed to maximise total supply chain effectiveness and profitability. Supply Chain Management monitors the movement and storage of raw materials, work-in-process inventory, and finished goods from point of origin to point of consumption. (Harland, C.M. (1996) Supply Chain Management, Purchasing and Supply Management, Logistics, Vertical Integration, Materials Management and Supply Chain Dynamics. UK: Blackwell.) Supply chain management plays a crucial role in business as it enables firms to clearly see how much each input is contributing to the final value of the good or service being produced. Through this evaluative stage, a business may be able to alter their supply chain to maximise profitability and customer satisfaction through improved products. There are various tiers of a supply chain which include goods and services, information and financial flows.

List and describe the five components of a typical supply chain

Plan	Firm must have a plan for managing al resources that go toward meeting customer demand for g/s
Source	Firms must carefully choose reliable suppliers
Make	Manufacturing stage
Deliver	Known as logistics: set of processes that plans for and controls the efficient and effective transportation and storage of goods
Return	Most problematic step in supply chain – firms must create networks for receiving defective and excess products and support customers w/ problems with their goods

The five persons in the supply chain include: (these may change depending on what business model is used e.g. e-commerce)

1. supplier

2. manufacturer

3. distributer

4. retailer

5. customer

Define the relationship between IT and the supply chain

IT plays a crucial role in the supply chain. IT enables the integration of process and information linkages between functions of a firm or between other firms, suppliers, customers etc to be analysed. IT also enables firms to monitor their supply chain and through the information gathered from this stage create informed forecasts and plans for future business goals and objectives. SCM heavily relies on IT to make accurate decisions regarding inventory, need for business processes, reducing costs etc. Without IT, it would be impossible to accurately monitor a large supply chain.

Week Seven: Weekly Questions

1. Explain the business benefits of using wireless technology.

There are various benefits businesses may experience through the use of wireless technology. Wireless technology enables firms to gain a universal access to information and applications. The use of such technology enables people and mobile devices to gain access to information globally 24/7 from either their beds or their office desks. Wireless technology also proves to be a beneficial process for firms as it enables the automation of business processes. This means that wireless devices are able to centralise business processes and abolish processes that prove to be unnecessary e.g. products may be ordered using a wireless device such as an iPhone rather than a wired computer. Lastly, wireless technologies also prove to be beneficial for businesses as such technology enables convenience to be achieved. This can be displayed as employees are able to access the internet to check their emails or to engage on online teleconferencing online from the airport or from their homes. The overall benefits of using wireless technology are:

- ability to have mobile machines

- less hardware/IT infrastructure required

- increased productivity as processes/systems are available 24/7

- greater convenience

- universal accessibility

2. Describe the business benefits associated with VoIP

VOIP proves to be very beneficial for firms as it uses TCP/IP technology to transmit phone calls using internet technology enabling calls to be transferred at a faster rate. VOIP does not require traditional cooper wire running through the users house and prevents consumers from being reliant on Telstra or other telecommunication providers for voice traffic. Also, the use of VOIP as it disintermediates the use of a phone line, proves to be much cheaper than traditional methods of calling people. Therefore, VOIP proves to be beneficial for most firms as it involves cheaper telephones and lower operating costs. VOIP services are also easier to relocate for if a firm moved its business and convergence provides lower cost WAN connectivity. (http://www.alltel.com.au/voipbenefits.html)

3. Compare LANs and WANs

Local area network (LAN): designed to connect a group of computers in proximity of each other

- enables sharing of resources e.g. files, printers through authentication and authorisation

- connects to other LANs and to the internet

Wide area network (WAN): spans a large geographic area e.g. state or country & connect multiple smaller networks e.g. local area networks

• data communication links between companies and suppliers or customers successfully enable strategic advantage e.g. in Notre Dame network systems in Perth are connected with systems in Sydney

Therefore, LANs connect computers in close proximity to each other, whereas, WANs are able to connect computers dispersed over a large geographical region.

4. Describe RFID and how it can be used to help make a supply chain more effective.

Radio Frequency Identification uses active or passive tags in the form of chips or smart labels that can store unique identifiers and relay this information to electronic readers. Such RFID tags are often smaller than a grain of sand and combine tiny chips with an antenna. RFID can be used to help make a supply chain more effective as because RFID’s are regularly used in the tracking of inventory, they will be able to replace barcodes and enable the transmission of stronger and more accurate data.

Unusual uses of RFID

• preventing toilets from overflowing
• identifying human remains
• getting into nightclubs
• cooking with robots
• timing athletic events

Common uses of RFID

• passports contain chips that instantly send data regarding the time/place of a passenger
• transportation: eTags are used to pay tolls

SUMMARY:

A RFID is a small device that can send information back to a large database. RFIDs are beneficial for the supply chain as movement of goods and services from manufacturers to customers can be tracked using an RFID scanner. This promotes efficiency and productivity and allows stock that is on 'par level' to be counted systematically.

Week Six: Questions

1. List, describe and provide an example of each of the five characteristics of high quality information.

It is crucial that firms ensure that their information is constantly of a high quality. There are various attributes of high quality information. Five characteristics include accuracy, completeness, consistency, uniqueness and timeliness. It is essential that the information entered into the database of a firm is accurate and precise as if data is incorrectly entered into a firms system, problems can result. For example, if a salesperson incorrectly enters the address of a customer, the product they ordered may not be delivered to the correct address and may go missing. Information must also be complete. This means that if an employee enters information into a database, all of the information must be entered into the system. Incomplete data entry will also cause dilemmas for a business. For example, if an employee fails to write the suburb and postcode of a customers address, a product will not be able to be sent. Information must also be consistent. This ensures that data is reliable. For example, it would be unacceptable for an employee to type a different street number for a customers address as this would create confusion. The information of a firm should also be unique. This means that data should not be replicated in another system which contains different information. For example the address of a customer should be unique and there should only be one address for that customer. If the customers address appears different in a different system of the firms, the data is not unique. Lastly, for information to be of a high quality, it should be timeliness. This means that information should be current and up to date. For example, firms need to ensure that they are updated with the changing addresses of their clients for billing and shipping purposes.

2. Define the relationship between a database and a database management system

A database is a structured collection of related data and a database management system provides users access to that data. Therefore, it can be displayed that databases and database management systems areinevitably linked and are interdependent of one another.

Example of a Database (http://www.quackit.com/pix/database/tutorial/dbms_sql_server.gif)

3. Describe the advantages a business can gain from using a database

There are various advantages attributed to the use of databases. The advantages that a business would experience from using a database would include increased flexibility. This is because data contained on a database is readily accessible by a wide range of employees. Databases also provide increased scalability and performance as they are able to adapt to changing demands and are able to quickly perform certain tasks/processes. Databases are also advantageous as they reduce information redundancy which is the replication of data over various systems. Information integrity is another advantage associated with the use of databases within a firm. This refers to the quality of data which is ensured through the use of databases. Information security is another advantage associated with the use of databases as databases usually contains strong security features such as passwords, and restricted access levels and controls confining the number of users who can access the firms valuable information contained on the database.

4. Define fundamental concepts of the relational database model

A relational database model is a database that stores information into logical two dimensional tables consisting of rows and columns. There are four key fundamental concepts associated with relational database models which include entities and attributes as well as keys and relationships. An entity in the relational database model is a person, place, thing, transaction or event for which information is stored. Attributes are also included in database models and consist of fields or columns that are characteristics or properties of an entity or class of information. Keys are used in databases to manage information. A primary key is a field that identifies a given entity in a table e.g. customer ID number. A foreign key in the relational database model is a primary key of one table that appears as an attribute in another table and acts to provide a logical relationship between the two tables.

1. 5. Describe the benefits of a data-driven website.

A data-driven website is an intriguing website that is regularly updated to include information specific gained from the firm’s database for its customers. There are various benefits associated with the use of data-driven websites. An advantage of a data-driven website is the enabling of constant development. This type of website enables website owners to make changes to the content of the website at any time. Content management is another benefit of a data-driven website and enables a programmer to make updates whenever needed. Future expandability is another benefit of data-driven websites as such website enables the site to grow faster than it would be possible with a static website (this is done through the constant changing of the websites layout). Data-driven websites also prove to be beneficial as they minimise human error as the information contained on the website is directly linked to the database of a computer, thus doesn’t need to be reentered. Data-driven websites also advantageously allow improved the stability of a firm as such website enables firms to keep track of all their files and information in an easy to view format.

1. 6. Describe the roles and purposes of data warehouses and data marts in an organization

A data warehouse refers to a database in which information is collected from various sources for the support in decision-making processes. They key role of data warehouses is to aggregate information into a single repository or location to enable management and employees with decision-making processes. Data marts are contained within data warehouses and are multi-dimensional cubes that contain layers of columns and rows of information. The purpose of data marts is to enable employees to easily view the components of different information/inputs within a database.
