Analysis, Implementation and Maintenance phases
The main goal of Plaining and Analysis Phases
1) To create Project Development Plan
2) To produce a list of requirements for a new or revised information system
Picture 4
1) Application development tool
2) Application software
3) Turnkey system
4) System from scratch
What is the 4th phase
Implementation phase
Correct the sentence:
1) blockchain info provides access to the entire Bitcoin blockchain
2) computer connected to Bitcoin network receives a part of a copy of the blockchain
3) blocks is reports with the most recent transactions recorded
4) completed transaction is publicly recorded and verified by other users
2) computer connected to Bitcoin network receives a full copy of the blockchain
What is the sequence of SDLC phases
1) Plaining
2) Analysis
3) Design
4) Implementation
5) Maintenance
find odd activity of planning phase:
1) assemble the project team
2) justify the project
3) choose a development methodology
4) develop a project schedule
5) obtain approval to implement new system

What is the design phase refers to?
Design phase refers to producing a plan for building the system and defining the architecture, interfaces and data structures.
Correct the sentence:
Before the system can move on to the fourth phase the customer again needs to sign off
There is nothing to be corrected
The definition of the information system
An information system can be defined as set of interrelated components that collect, process, store, retrieve, and distribute information to support decision-making, coordination, and control in an organisation.
What is SDLC stands for?
System development life cycle
It provides a general outline of how an information system evolves
Describe the activities of the Analysis phase
1) study current system
2) determine system requirements
3) write a requirements report
Why the design phase can be referred to as the transformation phase?
Because this is when an idea is actually transformed into a real working system.
The definition/goal of Implementation phase
The main goal of the Implementation phase is to create, test and convert a system and to train users
Name the four (and one additional) major types of information systems and describe them
1) transaction processing system
2) management information system
3) decision support system
4) expert system
(additional AI)
What are the most interesting ideas/things you can remember from the lessons?
(?__?)
What is system requirements stands for and why they sometimes called success factors?
Sys requirements are criteria for successfully solving problems identified in an inf sys. These req guide the implementation for new/updated sys. They also serve as evaluation checklist at the end of development project
Describe the activities of the Design phase
Activities: identify potential solutions; evaluate solutions and select the best; develop application specifications; select hardware and software; obtain approval to implement the new system;
What risks and challenges can emerge during the implementation phase?
1) Delays in the schedule
2) Unforeseen technical problems
3) Changing requirements
4) Integration problems
5) Insufficient testing
What is information system made of? Characterize each component
Hardware software people data networks (изменено)
Explain project justifying and name elements of project development plan
Justifying a project often involves identifying problems and opportunities within an organisation's current inf system. By eliminating problems & taking advantage of opportunities, an org-ion can become more competitive.
-short description of project+scope
-justification for the project(costs,financial benefits)
-list of participants
-schedule(+deadlines)
How project team can determine system requirements?
Describe all the software alternatives
Describe the activities of the Implementation phase (6)
Activities:
1) purchase and install hardware and software
2) create applications
3) test applications
4) finalise documentation
5) convert data
6) convert to the new system
7) train users
