Healthy Harvest Grocery App Development: Why Structure Matters

Slide 1: Introduction & Project Overview

• Welcome & Introduction: Briefly introduce yourself and your role as IS consultant.
• Project Scope: Explain Healthy Harvest’s desire for an online grocery ordering app with pickup/delivery options.
• Joan’s Concern: Acknowledge Joan’s time and cost concerns.

Slide 2: Systems Development Life Cycle (SDLC)

• What is SDLC? A structured approach for developing information systems with defined phases.
• Benefits: Reduced risk, cost savings, improved quality, and project transparency.
• Diagram: Illustrate the phases: Planning, Analysis, Design, Development, Testing, Implementation, Maintenance.

Slide 3 & 4: Methodology Options

• Waterfall Methodology:
  • Diagram: Sequential workflow where tasks in each phase must be completed before moving to the next.
  • Tasks: Feasibility study (Phase 1), system requirements (Phase 2), app design (Phase 3).
  • Benefits: Structured, clear deliverables, ideal for well-defined requirements.
  • Drawbacks: Rigid, inflexibility to changes, longer development time.
• Agile Methodology:
  • Diagram: Iterative and incremental approach with sprints of development and feedback.
  • Tasks: User stories and backlog creation (Phase 1), prototype development and testing (Sprints).
  • Benefits: Adaptable to changes, faster feedback, continuous improvement.
  • Drawbacks: Requires strong project management, may not suit strict deadlines.

Slide 5: Importance of Structured Analysis & Design

• Why is it important? Ensures a well-defined, efficient, and user-friendly system.
• Example: Unstructured analysis could lead to missing key features, poor user interface, and costly rework.
• Structured techniques: Data flow diagrams, entity-relationship diagrams, user interface mockups.

Slide 6: SDLC & Analysis Phase (Waterfall)

• Task 1: Requirements Gathering: Interviews, surveys, and workshops to understand user needs and system functionalities.
• Task 2: Process Flow Analysis: Mapping out the steps involved in ordering, payment, and fulfillment.
• Deliverable: Functional and non-functional requirements document outlining app features and specifications.

Slide 7: SDLC & Design Phase (Waterfall)

• Task 1: User Interface Design: Creating wireframes and mockups for a user-friendly and intuitive app layout.
• Task 2: Database Design: Defining data structures and relationships to store product information, user accounts, and orders.
• Deliverable: Detailed app design document with screen layouts, data models, and technical specifications.

Slide 8: SDLC & Development Phase (Agile)

• Sprints: Each sprint focuses on developing specific features based on user stories and priorities.
• Tasks: Backlog refinement, coding, unit testing, and integration testing within each sprint.
• Deliverable: Working app prototype after each sprint for early feedback and iteration.

Slide 9: SDLC & Testing & Implementation (Both)

• Testing: Rigorous testing of app functionality, performance, and security at various stages.
• Implementation: Deployment of the app to production servers and user training.
• Benefits: Ensures quality, addresses bugs, and smooth user adoption.

Slide 10: Conclusion & Next Steps

• Recap: Value of SDLC, methodology options, and key tasks in each phase.
• Address Joan’s concerns: Structured approach saves time and money in the long run.
• Next Steps: Propose recommended methodology and timeline for Healthy Harvest’s app development.

Speaker Notes:

• Tailor the explanations and examples to Healthy Harvest’s specific needs and context.
• Use visuals and diagrams effectively to enhance understanding.
• Emphasize the benefits of each phase and task in relation to project success.
• Be prepared to answer questions and address Joan’s concerns regarding time and cost.

This presentation can serve as a starting point for further discussions and collaboration with Joan and her team. Remember, adapting the approach and methodology to the specific context and project requirements is crucial for successful development.
