SDLC Phases
The first phase where feasibility and project possibilities are analyzed.
Preliminary Analysis
This methodology was first developed in the 1960s to manage large software projects associated with corporate systems running on mainframes.
systems-development life cycle (SDLC)
The first generation programming language written in binary.
Machine Code
The decision between developing software internally or purchasing it.
Build vs Buy
This implementation methodology selects a particular date to stop using the old system entirely.
Direct Cutover
The result of the system analysis phase, this specific document details exactly what the system is supposed to do.
system-requirements document
This methodology focuses on quickly building a working model of the software, getting feedback from users, and then updating the model.
RAD (Rapid Application Development)
This generation of language is called machine code and is programmed by directly setting actual ones and zeroes.
first-generation
The challenge when modifying purchased software during updates.
Customization Management
During this final phase, IT management must ensure the system continues to stay aligned with business priorities and runs well.
maintenance phase
In the testing phase, this specific type of test checks individual parts of the code for errors or bugs.
unit test
Based on a 2001 "Manifesto," these methodologies utilize small cross-functional teams and daily status meetings.
agile methodologies
This runtime program must be installed to interpret and run Java code on different types of operating systems.
Java Virtual Machine (JVM)
When departments outside of the IT department develop their own specific applications, it is referred to by this term.
end-user computing (or end-user development)
This implementation methodology is the least risky but by far the most expensive because work is duplicated
Parallel Operation
A key part of the preliminary analysis step is this type of analysis, which evaluates technical, economic, and legal factors.
feasibility analysis
In the lean methodology, this is a working software application with just enough functionality to demonstrate the idea behind the project.
minimum viable product (MVP)
This type of programming language is designed to allow a programmer to define a specific starting point for the program and then execute sequentially.
procedural programming language
This person's role is to make various purchased systems and the existing systems at the organization work together.
Systems Integrator
In this implementation approach, different functions of the new application are used as functions from the old system are turned off.
Phased Implementation
