Software Engineering Principles Practical Advice and Steps for Managing Your Project

Getting Started The Process: Identifies the “Big Picture” Tasks The Project Management Plan: Outlines the “road map” to go from start to finish The Principles: Practical advice for guiding your work in each major framework activity

Problem Solving Principles Understand the Problem Communication, Requirements Gathering Plan a Solution Planning, Modeling, Designing Carry Out the Plan Implementation Examine the Results Testing, Delivery, Feedback See detailed questions pg 98 6/e

Step One: Communication Listen!! Customer, Advisor, End-User, Team Members, Conscience, etc. Prepare Get to know the customer’s context for more effective communication Prepare questions to guide the discussion and to avoid missing ideas Facilitate Assign a facilitator to keep the agenda moving Face-to-Face Document Record the important points, constraints, or decisions Collaborate Keep all stakeholders involved in defining the system Stay Focus Draw a Picture Keep Moving Negotiate a Winning Position for Everyone See task set pg 103 6/e

Step Two: Planning Understand the Project Scope Get Customer Concurrence on Plan Prepare to Iterate Over the Plan Estimate You must estimate to plan, if you can’t give a good estimate, then you’ll need to decompose the problem (or learn more about it) until you can Consider Risk Be Realistic Refine/Adjust Details as Milestones Approach Prepare to Measure Quality Prepare to Control Change Track Your Plan See task set pg 107 6/e Should be actively working tasks 1-8, beginning task 9

Step Three (a): Analysis Modeling Model the information What needs to be known to accomplish the problem Define the functions What things need to done to the information Define the behavior How will the software operate (external appearance) Modeling is best accomplished hierarchically Model beginning with concept (what) and proceed later to form (how) See task set pg 109 6/e

Step Three (b): Design Modeling Design should result from analysis Design should consider s/w architecture Give thought to your data structures Give extra care to communicate across interfaces Keep the end-user in mind when create the UI Keep components cohesive Keep components loosely coupled Keep your designs simple and easily understood Develop the design iteratively See task set on pg 112 6/e

Step Four (a): Construction-Coding Prepare to write code Follow structured programming techniques Follow your design If your tempted to deviate from your design, the return to the design step and re-think it from that perspective Use good style Meaningful names, comments, indentation Consider testing before coding Review what you’ve written with others Test your code Refactor your code to keep it clear See task set pg 114 6/e

Step Four (b): Construction-Testing Test requirements Plan test before you code Focus your test efforts Bugs tend to lurk in the same places: interfaces, boundaries, special conditions, cases, memory management, and complex code Test beginning small and proceeding to large Exhaustive testing is not possible (or desirable) See task set pg 115 6/e

Step Five: Deployment Manage customer expectations Keep them informed Keep your promises Delivery package should be tested in the deployed setting Plan for support after delivery Give real attention to providing end-user instructions on using the s/w Do not deliver buggy software—fix it first See task set pg 115 6/e

Additional Points of Emphasis General Principles for any Project (pgs ) Provide value – Reason for effort Keep it Simple Maintain Vision Understandable Products – Communicate Downstream Open to Future Plan for Reuse Why we model (pg 105 7/e,107 6/e) Types of Tests (unit, integration, validation and user, pg 111 7/e, 113 6/e)
