What are the factors that need to be considered when implementing a new computer system?
Requirements, support for future developments, costs, benefits, time development estimates, possible difficulties and alternative solutions, risks, review of previously proposed solutions, hardware/software issues, ethical considerations, current aspects which can be reused.
Define the limitations of the new system using the T.E.L.O.S. framework.
Technical feasibility, Economic feasibility, Legal feasibility, Operational feasibility, Schedule feasibility.
What are the potential compatibility issues that may arise when merging software from two entities?
Language barriers, patents, data migration, different file types.
Why is it important to consider support for future developments when implementing a new computer system?
To ensure that the new system can adapt and evolve with the changing needs and advancements in technology.
What is the significance of reviewing previously proposed solutions when implementing a new computer system?
To learn from past experiences, identify potential challenges, and explore alternative solutions based on lessons learned.
How does operational feasibility impact the implementation of a new computer system?
It assesses whether the existing organizational practices and procedures are sufficient to support the maintenance and operation of the new system.
What are some disadvantages of legacy systems?
Costs for maintaining older systems may be higher, technical support may no longer be available, and they tend to be more vulnerable to security threats due to a lack of security updates.
Define Software as a Service (SAAS).
Software as a service is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted.
What are the advantages of Software as a Service (SAAS)?
Lower upfront cost, quick setup and deployment, easy upgrades, accessibility, scalability, and expert support.
List some applications for which Software as a Service (SAAS) has become a common delivery model.
Office and messaging software, payroll processing software, DBMS software, management software, CAD software, development software, gamification, virtualization, accounting, collaboration, CRM, MIS, ERP, invoicing, HRM, talent acquisition, CM, antivirus software, and service desk management.
What is the goal of the analysis stage in the software systems life cycle?
The goal of analysis is to determine where the problem is, in an attempt to fix the system.
What is described in detail during the design stage of the software systems life cycle?
In systems design, the design functions and operations are described in detail, including screen layouts, business rules, process diagrams, and other documentation.
What are some disadvantages of legacy systems in terms of security?
Legacy systems tend to be more vulnerable to security threats due to a lack of security updates.
How is Software as a Service (SAAS) typically accessed by users?
SaaS is typically accessed by users using a thin client via a web browser.
What are some factors considered during the implementation of a new computer system?
Connectivity requirements, performance, security, and limited range of applications are considered during the implementation of a new computer system.
Why may costs for maintaining older systems be higher?
Costs for maintaining older systems may be higher as the systems may fail more frequently with age.
This quiz covers the factors that need to be considered when implementing a new computer system, including the extent of the new system, requirements, support for future developments, costs, benefits, time development estimates, possible difficulties, risks, and ethical considerations.
