All systems development projects are prompted by a business need.
Systems development is a set of activities, methods, best practices, deliverables, and automated tools to creating and maintaining IT architecture and software.
Business need is a gap between the current state of a business and its goals.
A business driver is a condition, process, resource, or rationale that is vital for an organization to thrive.
Business Drivers

Globalization of the economy
E-commerce, mobile commerce
Security and privacy issues
Communication, collaboration, and partnerships
Knowledge management
Continuous improvement and total quality management
Business process redesign

System Development Life Cycle
System Development Life Cycle (SDLC) is a multiple stage approach used by IT professionals to develop high-quality information systems from planning and analysis through support and maintenance.
The SDLC provides a framework for a number of different systems development methodologies.
The activities performed during systems development vary depending on the size and complexity of the system.

Stages of the SDLC
Copyright ©2021 John Wiley & Sons, Inc.
7
Systems Planning
Systems Analysis
Systems Design
Implementation and Testing
Support and Maintenance
The SDLC is an iterative process, not a linear one.
Stage 1: Systems Planning
During Systems Planning:
Planning begins when a business need is identified.
Problem or desired change is described.
Planning stage objective is to determine feasibility of the request.
The deliverable from the planning stage is the Project Plan.
A feasibility study in this stage determines the probability of success of a proposed system and provides a rough assessment of its technical, economic, organizational, and behavioral feasibility.

Feasibility Analyses
Copyright ©2021 John Wiley & Son, Inc.
9
Technical feasibility determines if the required technology, IT infrastructure, data structures, analytics, and resources can be developed and/or acquired to solve the business problem.
Economic feasibility determines if the project is an acceptable financial risk and if the company can afford the expense and time needed to complete the project.
Legal and organizational feasibility Are there legal, regulatory, or environmental reasons why the project cannot or should not be implemented?
Behavioral feasibility considers human issues.
Stage 2: Systems Analysis
During Systems Analysis:
User requirements are gathered to better understand the problem
Process models are created to determine the logical design of the system
The deliverable from the systems analysis stage is the Systems Proposal.
More time invested in analysis mean a greater probability of IS success.
10
Copyright ©2021 John Wiley & Sons, Inc.
Stage 3: Systems Design
System developers utilize the design specifications to create the user interface and establish data requirements
Physical design of the system is designed by determining and acquiring the hardware and software needed to carry out the logical design of the system
User and system documentation are created
Management and user involvement are critical to ensure that business requirements are being met
The deliverable from the design stage is the System Design Specification

11

Stage 4: Implementation and Testing
Implementation
Conversion of the old system to the new system
Plunge: cut off and migration at a specific time
Parallel: simultaneous transfer
Pilot: limited test of new, then roll out
Phased: specific components in stages
Testing
Testing verifies that apps, interfaces, data transfers, and so on, work correctly under all possible conditions.
Users are trained in the use of the new system.
12
Copyright ©2021 John Wiley & Sons, Inc.
Stage 5: Support and Maintenance
Occurs once new system’s operations are stabilized.
Audits are performed to assess capabilities and determine operational correctness.
Maintenance must be kept up to date at all times.
Users kept up to date on latest modifications and procedures.
Systems development is a repetitive process as maintenance turns into the development of a new system.

Comparing Systems Development Methodologies
Software Development Methodologies: Waterfall
Waterfall Method
Sequential
Predictive
Inflexible
No going back
Recordkeeping essential
Small, short-term projects
Copyright ©2021 John Wiley & Sons, Inc.
17
Software Development Methodologies: Object-Oriented
Object-Oriented (O-O) Analysis and Design
Iterative, Adaptive
Emphasizes modularity and reusability
Views a system as a collection of modular objects that encapsulate data and processes.
Objects = people, things, transactions and events
A use case has two parts: use-case diagram, which is a visual summary of several related use cases within a system; and a use-case description, which is a text-based description of the business event and how users will interact with the system to accomplish the task.

18

Software Development Methodologies: Agile
Agile Methodology
Most flexible of all development methodologies
Software components delivered early and often
Iterative, incremental approach
Variations: Scrum, Kanban, Scrumban, and extreme programming

Agile software development methods
22
Copyright ©2021 John Wiley & Sons, Inc.
Scrum is a framework that consists of small self-organizing, cross-functional Scrum Teams who work together to produce small pieces of a system iteratively and incrementally in sprints to maximize opportunities for feedback.
Kanban is Japanese for a signboard. It is a visual process and project management methodology used in systems development projects.
Scrumban combines certain aspects of Scrum and Kanban originally designed as a way to transition from Scrum to Kanban.
Extreme programming emphasizes business results first and takes an incremental approach to building software, using continual testing and revision.
Software Development Methodologies: DevOps
DevOps: DEVelopment and IT OPerations
Emphasizes collaboration between software developers, operators and testers involved in the development and operations of information systems
Developed to address gap in communication and collaboration
Creates culture where building, testing and delivery of a system can happen quickly, frequently and reliably
Lowers failure rate of new releases
Shortens time to market

Systems Development Tools and Techniques: JAD, RAD, and Prototyping
Joint Application Development (JAD) is a team-oriented technique used in the planning and analysis stages of the SDLC to collect business requirements.
Rapid Application Development (RAD) is an interactive process used throughout the SDLC continuing until the system is completely developed and all users are satisfied with the outcome.
Rapid Prototyping is an iterative process used to quickly create an early sample, model or release of a system to test a concept or process.
A prototype is a working model of a system or part of a system usually built to demonstrate it to users, who can test it, and request rework as necessary.

Systems Development Tools and Techniques: CASE Tools
CASE tools refer to software used to automate systems development. There are three classes of CASE tools that automate many of the SDLC activities:
Upper CASE tools: Used in the planning and analysis stages of the SDLC to perform repetitive activities such as gathering requirements, diagramming processes, and presenting them in an organized way.
Lower CASE tools: Used in the design, implementation/testing, and support/maintenance stages of the SDLC to automatically generate code, test for functionality and defects, monitor implementation, and perform software maintenance activities.
Integrated CASE tools: Used in all the stages of the SDLC from requirements gathering to testing and documentation.
27

Systems Development Tools and Techniques: Code Generators
A source code generator automatically generates common application source code in any computer programming language, for example, BASIC, VB, PHP, ASP, NET, SQL, C#, Java Script.
A low-code development platform is software that provides developers and nondevelopers with an intuitive graphical user interface instead of a traditional computer programming environment to create apps.

Project, Program and Portfolio Management
Project, Program and Portfolio Management (PPPM)
Project is a temporary endeavor undertaken to create a unique product, service, or result.
Program is a group of similar or related projects that are managed and coordinated as a group.
Portfolio is group of unrelated programs within an organization that are managed holistically to achieve strategic goals.

31

32
Project, program and portfolio management occurs at different levels of an organization’s hierarchy.
Management of individual projects occurs at the operational level of an organization.
Programs are managed at the tactical level, and portfolio management is an integral part of business strategy.
Project Management
The discipline of using established principles, procedures, and policies to successfully guide a project from start to finish.
A project is the lowest component in the hierarchy of project, program and portfolio management (PPPM).
Each project has a set time to start and a deadline for completion.
Project sponsor is a person or organization that approves and/or supports the allocation of resources for a project, defines its goals, and evaluates the success of the project at completion.

34
Project success
Project success is becoming increasingly reliant on four things:
Engaged executive sponsors
Projects aligned with organizational strategy
Control over scope creep
High project management technology quotient (PMTQ): PMTQ is a person’s ability to adapt, manage, and integrate technology based on the needs of the project or the organization.
35
Copyright ©2021 John Wiley & Sons, Inc.
The Role of the Project Manager
The project manager is the central point of contact in a project.
The project manager’s main responsibility is to manage the triple constraint—scope, time, and cost—to meet project objectives while ensuring project quality.
Successful project management is not only built on creating and managing systems and processes, but also requires developing and maintaining strong relationships with all project stakeholders.
36

37
Program Management
Occurs at the tactical level of an organization
A program is a group of related projects
A program doesn’t always have a single, clearly defined deliverable or timeline
Managing related projects as a group in an overarching program results in much better utilization of resources than a single project.
Benefits that an organization can realize from using a structured approach to program management include increased synergy between projects, optimal use of resources, less resource constraints, improved communication through better coordination among projects, and ultimately better business performance.
38
Copyright ©2021 John Wiley & Sons, Inc.
The Role of Program Manager
They provide oversight to ensure that each project in the program is completed effectively and efficiently to produce quality deliverables that meet stakeholder requirements.
Their focus is on overseeing project work and resources in projects that are currently in their program.
This focus on current projects ensures work and resources are moving between projects at the right time and that resource needs of all projects are met.
A project manager creates a master schedule to manage the dependencies between project, a risk manager plan, and a communication strategy to ensure that any changes that are necessary.
39
Copyright ©2021 John Wiley & Sons, Inc.
Portfolio Management
Occurs at the strategic level of the organization
Is the centralized management of all projects currently proposed, in progress, or planned for the future to identify investment synergies, resource and budget considerations between projects
Looking at projects holistically enables executive management to review portfolios and programs, to determine which projects are or are not necessary, and in what order they should be completed
40
Copyright ©2021 John Wiley & Sons, Inc.
The Role of the Portfolio Manager
Some of the responsibilities of the portfolio manager are as follows:
Map proposed projects to overall organization objectives and strategies.
Assess the value that a proposed project brings to the company.
Assess the complexity of proposed projects.
Prioritize project proposals for project selection.
Prioritize programs to keep up with changing business strategies.

PPPM Frameworks
44
Copyright ©2021 John Wiley & Sons, Inc.
The two most widely used PPPM frameworks are:
PMI® Project Management Body of Knowledge (PMBOK 6e):
currently the definitive guide for managing projects of all types.
Developed in the United States by the PMI.
PRINCE2 (PRojects IN a Controlled Environment):
a project management methodology developed by the Cabinet Office in the United Kingdom and currently managed and developed by AXELOS
45

The Project Triple Constraint
Scope: The project scope is the specification of what the project is supposed to accomplish—
Time: A project is made up of tasks. Each task has a start date and an end date.
Cost: This is the estimation of the amount of money that will be required to complete the project.
