1.1.1 Identify the context for which a new system is planned
Planning a new system
Planning a new system
Planning a new system is the process of thinking about various details and organizing the activities required to achieve the desired goal.
Extent
Extent
How large is the system?
How powerful is it?
How many users does it have?
How much hardware is required?
Extent for Powerschool (example):
Web based site, so no specific software needed.
Parental access.
Accessible attendance, records absences, reports.
Centralized data storage.
Decreases paper use.
Extent for Google Drive (example):
Web based site, no specific software needed.
Accessibility through compatibility with tablets, computers, smartphones, etc.
Collaboration with multiple users who can synchronously access and edit resources.
Cloud based storage, reduced possibility of data loss.
Limitations
Limitations
What prevents the system from exceeding certain limits?
What restrictions are there that cannot be overcome?
Limitations for Powerschool (example):
No access without internet connection.
Staff training required.
Risk of security breaches and/or hacking.
Dependence on third party company for data management.
Limitations for Google Drive (example):
Limited functionality without internet connection.
Data privacy issues as data can be sold by Google for marketing.
Dependency on a single company for data retrieval.
Possible reasons for creating a new system
Possible reasons for creating a new system
To replace a system (old) that is inefficient, no longer suitable for its original purpose, redundant and outdated.
To increase productivity
To improve quality of output
To minimize costs
Reduce errors or flaws of an existing system
Actions involved in updating a computer system
Actions involved in updating a computer system
Training new employees to use the new system
Changing the physical location of a server or other technology devices involved in the new system
Changing employees (firing, hiring, moving to other positions)
Planning/Updating a system entails the following tasks
Examine the existing system and know how it works
Evaluate the current system and see what could be changed and improved based on the organization’s needs
Identify the parts of the current system infrastructure that can (still) be used without compromising quality and productivity
Evaluate the software and hardware needs for the new system and the manpower necessary to make the implementation successful
Review goals for implementing a new system
Organisational issues to anticipate in planning a new system
Organisational issues to anticipate in planning a new system
Lack of guiding organizational and business strategies
Lack of stakeholder and end-user involvement
Lack of end-user ‘ownership’ of system
Lack of attention to required training
Lack of attention to various organizational issues, such as organizational culture
Lack of attention to the design of tasks and jobs, allocation of information system tasks, and the overall usability of the system.
Features that need to be considered when planning a new system
Features that need to be considered when planning a new system
Roles/activities of the users (eg permissions, security, partitions, collaborative work);
Resources (HW and SW equipment) appropriate for the organization;
Costs/budget limits;
Delivery time;
Compatibility with the old system (data);
Aspects of data to be considered when planning a new system
Aspects of data to be considered when planning a new system
The type of access needed;
For example read only/read write/online or offline;
Access rights;
For example, data available only for administrators / different permissions for students;
Frequency of access;
Some data (of non-current students) are not frequently accessed and can be archived;
Other data (of current students) are frequently used, subject to a variety of operations;
Quantity/size of the data;
For example should not exceed storage capacity of the new system;
Type/nature/format;
For example incompatibility issues;
Feasibility Report/Study
Feasibility Report/Study
noun - feasibility - the state or degree of being easily or conveniently done. i.e "the feasibility of a manned flight to Mars"
Feasibility report/study - "A report or a study that evaluates and analyzes a project and its potential based on technical, economical, legal, operational and scheduling criteria. It is used to decide whether the proposed project should be pursued."
1. Technical feasibility
Is the existing technology sufficient to implement the proposed system?
Can the existing technology sustain in the operation of proposed system?
2. Economic feasibility
Is the proposed system cost efficient.
Identifies any expected benefits
3. Legal feasibility
Are there any conflicts between the proposed system and any regulations/laws?
Identify the unforeseen/future legal issues
4. Operational feasibility
Are the existing organizational practices and procedures sufficient to support the maintenance and operation of the new system?
Does the organization have the appropriate skills and manpower to implement the new system?
5. Schedule feasibility
What is the time frame?
How long the project will take.
