  1. CS466: Tools and Processes for Software Gio Wiederhold Dorothea Beringer Anca-Juliana Stoica Overview Software Engineering

  2. Goals, Lectures Goal: • Overview of some important topics of software engineering • Basis for future studies - ongoing education • UML modeling • Design patterns • Software development process models • Software reuse, component-oriented software development • Software cost estimation • ... • Different views, invited speakers Overview Software Engineering

  3. Sign Up • check out http://www-db.stanford.edu/cs446 Overview Software Engineering

  4. Assignments • Modeling with UML • Assignment 1: Actors and Use Cases, Domain Model, for an electronic bookstore • Assignment 2: Design Model and Interaction diagrams for same problem as in assignment 1 • Assignment 3 (reverse engineering): Given a small software package and an incomplete use case model, make the interaction diagrams, the class diagram, a state chart, and try to model two additional features • Design Patterns • Assignment 4: apply and detect design patterns while modeling two (three) smaller problems • Cost Estimation • Assignment 5: Develop an estimate for a software product using tools and models: getting problem solution, analysis of results, option analysis, opportunity analysis, personnel impact, addressing the risks, model calibration Overview Software Engineering

  5. Books for Assignments UML modeling: • "UML distilled", by Martin Fowler, 1997/1999 or another UML book Design Patterns: • "Design Patterns", by Erich Gamma, Richard Helm, Ralph Johnson, John Vlissides, 1994or another book containing the GoF design patterns Overview Software Engineering

  6. Assignments: how to • Teams of two allowed for some assignments • Assignment 4 and 5: plan ahead! • Due dates: mostly Monday, yet plan for previous Friday!No late days! • Modeling assignments: require thinking and redoing. Goal is not to have just a model, but to have a good model! Overview Software Engineering

  7. Reading for specific lectures • "No Silver Bullet: Essence and Accidents of Software Engineering", for Sept. 27 • "A Spiral Model of Software Development and Enhancement", for Oct. 6 • A case study for the lecture on software reuse organizations, for Oct. 13 • "Risk Management for Software Development", for Oct. 16 • "Software Cost Estimation", "Estimating work with use cases", for Nov. 17 Overview Software Engineering

  8. NO Silver Bullet... Why no easy remedies? • Progress in hardware and thus possibilities for ever more complex software • Inherent characteristics of software (essence): • invisibility, many dimensions, hard to visualize • complexity, non-linear in scaling up • conformity, arbitrary complexity, interfaces • changeability, no classic production, glue, takes over soft parts of processes • Accidental difficulties: • ... Overview Software Engineering

  9. Tools and Processes for Software (1) What do we need to develop a software system? • Basictools: Languages, Compilers, Debuggers • Basic know how: Basic tools, Language features, Algorithms, ... • More advanced tools: Libraries, Databases, Window-systems, Distribution-systems, … • More advanced know how: Features of advanced tools and their languages, Distributed architectures, Solutions to specific problems, … Let’s start developing the new baggage-control system for the next new airport…. or do we need something else? Overview Software Engineering

  10. Processes and Tools for Software (2) n o c o n t r o l, i.e. for larger projects ( > a few hours): - results not predictable - schedule unknown - organizational chaos - random communication p r o j e c t m a n a g e m e n t Overview Software Engineering

  11. Processes and Tools for Software (3) d a m a g e d g o o d s unpredictable and unexpected behavior q u a l i t y a s s u r a n c e Overview Software Engineering

  12. Processes and Tools for Software (4) a d h o c h a n d c r a f t i n g e n g i n e e r i n g- planning- documenting- testing Overview Software Engineering

Silver Bullets Risk analysis Life-cycles Reuse Design Patterns Use-case driven Maintenance IEEE standards Evolutionary Prototyping SEI PMM Iteravite User acceptance ISO 9000 Spiral Paradigms Quality assessment Waterfall Requirements engineering Frameworks Component-management Reviews Participative development Objectory Configuration-management Inspection Activities Analysis Object-oriented Requirements elicitation UML Design Booch Phases Team building Process models Testing Walkthroughs RAD CASE-tools Software metrics Reliability Viewpoints Milestones Modeling techniques Project metrics Cost estimation TQM Overview Software Engineering

  14. Standards (1) There exist many standards: • Process models, e.g. Spiral model of Boehm, Objectory of Rational • SEI Capability Maturity Model • IEEE standards, e.g. requirements document, • ISO standards, e.g. ISO 9000 - 9001 Many companies have in-house standards: • complementing public standards (e.g. ISO 9000) • adaptations of public standards, methods and models Booch UML SEI CMM IEEE standards ISO 9000 Overview Software Engineering
