- Systems design
What is the definition of computer application?
Which of these two is a **modest scope **(Computer Application || Information System)?
Computer Application
What is the definition of Information System?
Which of the Software Development parts is ** broader in scope ** than the app
Information System
Which System development part Includes database and related manual processes (people)?
Information Systems
Information Systems Includes ……………. and …………….. ?
database & related manual processes
Define system development :
Systems analysis are those activities that enable a person to ………… and ……….. what an information system should accomplish
Understand 🧠and specify 📍
Systems design those activities that enable a person to ……. and ……… in detail the system that solves the need
إذا شفتي design
DDDesign & DDDescribe
Which of the system development parts
Is to determine WHAT the new system should Do?
System analysis
Which of the system development parts
Is to determine HOW the new system should be Build/ implemented
System design
What is the difference between computer, application and information systems?
What is the purpose of systems analysis? Why is it important?
Is enables the system developer to understand the user’s requirements.
T/F Without a good analysis of the user’s needs and requirements the new system will be inadequate in its solution or erroneous in its implementation.
True
What are the seven steps of software development?
1- Understand 🧠the need (business need)
2- Capture 📸the vision👁️
3- Define 📝a solution
4- Communicate 🗣️the vision 👁️and solution👆🏼
5- Build 🧱the solution
6- Confirm 👍that the solution meets 🫂the need
7- Launch 🚀the solution system
The process consisting of all activities required to build🧱, launch🚀, and maintain 🫳🏼an information system: (hint: there six)
System Development Life Cycle (SDLC)
What are the six core processes of the system development lifecycle ?
A Planned undertaking that has a beginning and end and that Produces some definite result
Project
What is Used to develop an information system?
Project
T/F a Project Requires knowledge 🧠 of systems analysis and systems design tools and techniques
True
What is the actual approach used to develop a particular information system?
System development process (methodology)
What is the other name of system development process?
Methodology
Give me three examples of system, development process, (a.k.a. methodology):
- Unified process (UP)
- Extreme programming (XP)
- Scrum
What does Most processes/methodologies now use ?
Agile and Iterative development
an information system development process that emphasizes flexibility to anticipate new requirements during development
Agile Development
Agile development: an information system development process that emphasizes ….(what?)….. to ………..(why?)……. during development.
Flexibility,
Anticipate new requirements
ايش هي صفات الـAgile Development
Fast feet
Responsive to change
Define Iterative development
Completes ✨ small🤏🏼 part of system (mini-project), then repeat 🔄processes to refine and add more, then repeat to refine and add more, until done☑️
The iteration development
What happens in core process 1 in pre-project initial activities?
- Identify the problem and document the objective of the system
-Obtain approval to commence the project
How can we Identify the problem and document the objective of the system in (core process 1)?
- Preliminary investigation تحقيق مبدئي
- System Vision 👁️ Document📑
How can we Obtain approval to commence the project in (core process 1)?
- Meet 🫱🏻🫲🏼 with key 🔑 stake🥩holders🍴
- Decision reached⛳️, approve 👍 plan 🧾and budget 💲
What should a system vision document include?
- Problem description
- System capabilities
- Business benefits
In which core process do we plan the project?
Core process 2
What happens in Day 1 (core process 2)?
- Determine the major components (functional areas) that are needed
- Define the iterations and assign each function to an iteration
- Determine team members and responsibilities
How can we Determine the major components (functional areas) that are needed in (Day 1 [core process 2])?
- **Supplier **information subsystem
- Product information subsystem
How to Define the iterations and assign each function to an iteration in (Day 1 [core process 2])
-Decide to do Supplier subsystem first
-Plan one iteration as it is small and straight forward
Which core process includes discovering and understanding details?
Core process 3
What are the activities of Day 2 Core Process 3?
- Do preliminary fact-finding to understand requirements
- Develop a preliminary list of use cases and a use case diagram
- Develop a preliminary list of classes and a class diagram
Which core process designs system components?
Core process 4
What happens in Day 3 ( Core Process 3)?
- Do in-depth 🌊fact-finding to understand requirements
- Understand and document the detailed workflow 🌬️of each use case
Look up supplier
Enter/update supplier information
Lookup contact information
Enter/update contract information
Are all a part of which subsystem ?
Cases of supplier information, subsystem
What happens in Day 4 (core process 4)?
- Design the database (schema)
- Design the system’s high level structure
How can we Design the system’s high level structure?
- Browser, Windows, or Smart phone
- Architectural configuration (components)
- Design class diagram
- Subsystem architectural design
Preliminary Design Class Diagram Includes ……………. and………….
- View Layer Classes
- Domain Layer Classes
…
What happens in Day 5 core process 4?
- Continue with design details
- Proceed use case by use case
Which core process builds tests and integrates system components?
Core process 5
What happens in Day 5 ( Core Process 5)?
- Continue programming (build)
- Build 🧱use case by use case
- Perform 🎤unit and integration tests
Which Core Process Complete System Testing and Deploy the System?
Core Process 6
What Happens in Day 6 (Core process 6)?
- Perform 🎤system functional testing
- Perform 🎤user acceptance ☑️ testing
- Possibly deploy ✈️part🤏🏼 of system
T/F Most iterations are longer (2 to 4 weeks)
True
End users need to be involved, particularly in which days?
1, 2, 3 and 6
Which days that end users don’t need to be involved
Days 4, and 5
(involved design and programming concurrently).
