planning system and installation Flashcards
what are the two important considerations when creating a new system?
the extent of it and the limitations of it
name at least three reasons why changing a system may be difficult.
– Users don’t like change (too often/at all)
– New systems might omit old features
– Old systems might be faster in certain circumstances
– People find change complex
– From a technology perspective, change might lead to incompatibility
– There might be data loss during migration
– It might be expensive (either in terms of money or time)
– basically almost any answer is okay just think abt it
what are the names of the four steps of changing a system?
plan
communicate
integrate
evaluate
explain the first step of changing a system.
plan - Before undertaking any change, a business needs to have a
clear and valid reason and mission for the change process.
explain the second step of changing a system.
communicate - The most important factor in changing anything within a business, small or large, is to communicate the change, and
its many factors, to the key stakeholders within the
organisation
explain the third step of changing a system.
integrate - If it’s possible for the change program of your
business to be adjusted, then open up your plans for
consultation with your stakeholder group
explain the last step of changing a system.
evaluate - It’s crucial that the organisation, its passage
through the change program, and the wider
organisation’s reactions to that change
program are evaluated at every feasible
opportunity
What is legacy system
old method/computer/programme/app that can not be purchased anymore (because it is old)
give at least three examples of legacy system as hardware.
– Floppy disks
– Parallel printer cables
– Connections like PS2
– basically any other.
give at least three examples of legacy system as software.
– Windows XP
– Movie Maker
– Industry specific software
– basically any other
give at least three examples of legacy system as a computer system
– Apple II Series
– Amiga
– Commodore 64
Whats a ,erger? Can you give three examples?
A combination of two entities or more, especially companies, into one.
Exxamples:
Disney and Pixar
Columbia and Sony pictures
Dream works and paramount
Can you name at least three problems that may arise when merging systems?
– Issues of software compatibility
– Language differences
– Time zone differences
– Workforce cultural differences
– basically anything else
Compare the implementation of systems using a client’s hardware with hosting systems remotely.
This looks like its a alot of things but actually you dont need to memorise this all you just need to be familiar with this.
- Location:
Client’s Hardware (On-Premises): The system is installed and maintained on the client’s premises, requiring physical space, power, and cooling.
Remote Hosting (Cloud): The system is hosted on infrastructure provided by a third-party cloud service provider, accessible over the internet. - Infrastructure Ownership:
Client’s Hardware (On-Premises): The client owns and is responsible for the hardware, networking equipment, and infrastructure.
Remote Hosting (Cloud): The cloud service provider owns and maintains the underlying infrastructure; clients subscribe to services. - Initial Setup and Deployment:
Client’s Hardware (On-Premises): Implementation involves procuring hardware, software licenses, and configuring the system on-site. It may have a longer lead time.
Remote Hosting (Cloud): Rapid deployment is possible, as infrastructure is provisioned by the cloud provider. Users can quickly scale resources up or down based on demand. - Scalability:
Client’s Hardware (On-Premises): Scaling may require additional hardware procurement and on-site adjustments, which can be time-consuming and expensive.
Remote Hosting (Cloud): Scalability is often more flexible and can be achieved by adjusting subscription plans or configurations through the cloud provider’s interface. - Maintenance and Upgrades:
Client’s Hardware (On-Premises): The client is responsible for maintenance, updates, and ensuring hardware reliability. Downtime may be required for upgrades.
Remote Hosting (Cloud): Maintenance and upgrades are typically managed by the cloud provider, reducing the client’s operational burden. Providers often ensure high availability during updates. - Cost Structure:
Client’s Hardware (On-Premises): Upfront costs for hardware and software licenses may be higher. Operational costs include maintenance, utilities, and staff.
Remote Hosting (Cloud): Often follows a pay-as-you-go model, with lower upfront costs. Clients pay for the resources they use, and operational costs are managed by the cloud provider. - Security and Compliance:
Client’s Hardware (On-Premises): Clients have direct control over security measures and compliance but must manage and implement them.
Remote Hosting (Cloud): Cloud providers invest heavily in security measures, but clients need to trust the provider. Compliance is often a shared responsibility between the client and the provider. - Connectivity and Accessibility:
Client’s Hardware (On-Premises): Local network infrastructure determines system accessibility, and remote access may require additional configurations.
Remote Hosting (Cloud): Accessible from anywhere with an internet connection. Cloud services often provide global accessibility without additional configuration.
In easy words explain what is local software and what is SaaS.
local - on premise, like buying a house - once and for all, but no one will clean it or protect it for you
saas (software as a servis) - like renting a house, but you get cleaned and safe
