A system could be a joined grouping of gadgets and completion frameworks, similar to PCs and servers, which will correspond with each other. Systems convey data in numerous mixed bags of situations, together with homes, minor organizations, and tremendous endeavours.

A). Functional areas are mainly used in large businesses, because they usually work in departments, each department work using the functional areas that relate to it’s particular area. They are mainly used to ensure that business activities are carried out efficiently and are need if a business is to achieve it’s aims and objectives. The main functional areas in a business are:

| In a business hierarchy, the level that is responsible for monitoring the daily activities of the business is

The next step in the process is system analysis. This second stage involves gathering requirements, such as documenting the strengths and weaknesses of the current system, having discussions with the users to understand their roles and needs. This is an integral part of the life cycle as employees are the most important asset a company has. Baya, Gruman, & Mathaisel state, “information technology

Consider the overall purpose of the system and at least two system options or alternative versions of the system capable of satisfying organisational requirements.

Understanding how goals of an organization and the roles of its stakeholders affect the selection process of an information system is vital to the success of that project. To ensure the execution of this task as well as its organization, efficiency, and accuracy, key leaders join creating a team of professionals ready for implementing change (Wager, Wickham Lee, & Glaser, 2009) . Learning how to select and acquire an information system, goals that should drive it and the roles of stakeholders is imperative to keep the project from failing.

Information systems serve as the pillars for a business to stand upon and maintain stability, productivity, and profitability. According to Stair and Reynolds (2015), one major retailer, Kohl's, considers, "information systems strategic to help drive sales, satisfy customers, and make key business decisions in the extremely competitive and constantly changing retail market" (p.4). Although one business's operations or industry may differ significantly from another business, the information systems employed by either one can be generally categorized into one of the following tiers: operational level, knowledge level, higher level, and strategic level. Furthermore, each one of these tiers encompasses subdivisions of specific information systems.

In class we have learned about various business information systems that aid in organizations experiencing more time and cost efficient solutions to internal and external challenges. At Shoppers Drug Mart, multiple business information systems are utilised to maximize profit and productivity. A transaction processing system is used at the point of sale to maintain a record of every transaction, including refunds and voids. The system records if the transaction was paid for in cash, debit, credit, or a gift card and possesses other features as

Functional Areas - The functional areas are the specialist areas of activity within an organisation. These include:

In each of these stage explains how the IT managers or Business Managers are planning the information systems for future use

System development can generally be thought of having two major components: systems analysis and systems design. In System Analysis more emphasis is given to understanding the details of an existing system or a proposed one and then deciding whether the proposed system is desirable or not and whether the existing system needs improvements. Thus, system analysis is the process of investigating a system, identifying problems, and using the information to recommend improvements to the system. System design is the process of planning a new business system or one to replace or complement an existing system.

A (As per the System Analysis and Design book 5th edition author,Dennis)This phase involves identification of who will use the system, what the system will do, and where and when it will be used.In this phase we develop analysis stratergy based on the current system built a new system and then gather information from clients for the development of new concept.The system concept is used to build a set of business analysis models.

First, we look what is the difference between system analysis and system design. System analysis is a problem-solving technique that decomposes the system into its component pieces and system design is a complimentary problem-solving technique that reassembles the component pieces of the system back into a complete system. When we are developing an information system, most organizations use a standard of steps. The steps are called development lifecycle(SDLC). SDLC consists of phases such as planning, analysis, implementation, design, and maintenance. Analysis phase is where you take a closer look and study the current system. The design phase, analysts design all aspects of the system, specifying on the system from input and output screens to database, computers, and report processes.

GIS is an abbreviation for Geographic Information Systems. GIS is a perfect blend of geography and technology. People can accumulate various forms of location data (both tangible and intangible) and produce living, breathing maps. By utilizing the power of Geographic Information Systems, users can create powerful applications. These applications can range in size from being small (surveying a single farm) to large (displaying real time voting across the country in a presidential election).
