IT and software • Just about every modern product or service depends on software • Software intensive products/services include: • the Internet • transportation of all kinds • financial markets
Software competence • Companies dependent on IT projects need to master the software technology to stay competitive • Produce quality products that satisfies user needs • Meet committed costs • Meet the planned schedules • 70 - 80 % of companies do not have a process able to support the demands of project control
What is software engineering? • Software engineering is concerned with applying scientific principles and management skills to develop software-intensive systems and products for use by society within the constraints of: • time: schedule • money: budget • technology: platform and domain • quality: safety, security, reliability, . . . • business: profit, stability, growth • ethics: serving society Acknowledgments: Dr. R.E. Fairley
Software Engineering - 2 Good software engineering practices Good PM practices for IT projects Software engineering practices lead to more successful projects
Why are software projects difficult ? • Invisible product • Lack of physical constraints • Inadequate systems engineering • Changing requirements • Co-ordination of intellect-intensive teams • Insufficient technical staff • Lack of project management skills
Project Failure Reasons Annual expenditures on software projects in the USA is $ 250B Successful - 16% ( $40B) Canceled - 31% ($ 80B) Over schedule & budget - 53 % ( $ 120B) Ref: Standish Group data
Major Issues • PLANNING: • Software requirements - not clear • Cost & schedule estimation - difficult • Projects function - not planned • CM, QA, computing facilities • Planning viewed as “non-productive” • CONTROL: • poor methods for tracking progress • poor indicators to measure productivity, quality
Fred Brooks - quote • “ IN MANY WAYS, MANAGING A COMPUTER PROGRAMMING PROJECT IS LIKE MANAGING ANY OTHER UNDERTAKING - IN MORE WAYS THAN MOST PROGRAMMERS BELIEVE. BUT IN MANY OTHER WAYS IT IS DIFFERENT - IN MORE WAYS THAN MOST PROFESIONAL MANAGERS EXPECT ” • The Mythical Man-Month, Preface to the First Edition
Software’s future - A Quote • “ .. the demand for software has grown at such an explosive rate, it now far outweighs the resources we have to produce it. ….. desperately needed software is not being developed…….. “ • “ An interaction of factors has caused this ‘software gap’: accelerated demand for software, increased complexity of systems, …. labor shortages, and lack of adequate science and technology to support robust development. “ President’s Information Technology Advisory Committee, ‘Interim Report to the President’, August, 1998
Recap … • Software remains a major cause of system failures • Complexity is growing • Keeping up with new techniques & procedures ? • Software engineering foundation “ We know why projects fail, we know how to prevent their failure -- so why do they still fail ? “ Martin Cobb Treasury Board of Canada
Two types of software projects ( ISO/IEC 12207) • Development • developing or modifying a software-intensive system to meet contractual requirements (satisfies user needs ) • Acquisition • Contractually obtaining from a group ( supplier), a software-intensive system for use by another group (user)

What is ISO/IEC 12207 ? • The major world-wide standard for software related processes • activities and tasks • Tailored for any organization or project • High level process architecture • An ‘inventory’ of processes from which to choose • For the first time - a world-wide agreement on what activities make up a software project
12207 Concepts • Process Architecture • Modular: Handle all types of projects • Cohesion: one process for one major function • Responsibility: One process for one party • 18 processes

Major Parties - Primary Supplier Acquirer Provides the product to the acquirer Acquires the product USER Operator Developer Maintainer Defines and developed the product Maintains the software product
The Acquisition Process • Defines the activities of the acquirer, • the organization that acquirers a system, software product or software service • 1. Initiation • 2. RFP ( tender) preparation • 3. Contract preparation and update • 4. Supplier monitoring • 5. Acceptance and completion
Organizational processes • Management • Infrastructure • Improvement • Training Project Life Cycle Employed by organization to establish and implement an underlying structure of .. Processes and personnel, and continuously improve the structure and processes
Management process • “The purpose of the management process is to organize, monitor and control the initiation and performance of any processes or functions within the organization to achieve their goals and the business goals of the organization in an effective manner” ( TR 15504-2) • Activities: • Initiation and scope definition • Planning • Execution and control • Review and evaluation • Closure
Infrastructure process • “The purpose of the infrastructure process is to maintain a stable and reliable infrastructure that is needed to support the performance of any other process. .. May include hardware, software, methods, tools, techniques, standards, facilities for development, operation, or maintenance.” ( TR 15504-2) • Objectives: • establish and maintain a well-defined software engineering environment (SEE)….. • tailor the SEE top the needs of the project... • develop a SEE that supports project team members • implement a defined and deployed strategy for reuse
Management & Infrastructure process standards • IEEE Std 982.1 - Standard dictionary of measures to produce • reliable software • IEEE Std 1045 - Software productivity metrics • IEEE Std 1058 - Software project management plans • IEEE Std 1045 - Recommended practice for the adoption • of CASE tools • ISO/IEC 14102 - Guidelines for the evaluation and selection • of CASE tools Standards provide the details of what to do
Supporting processes Project Life Cycle • Verification • Validation • Joint review • Audit • Documentation • Configuration management • Quality assurance • Problem resolution Employed by any Primary process or another supporting process:
Quality Assurance (QA) • “The purpose of the quality assurance process is to provide assurance that work products and processes comply with their specified requirements and adhere to their established plan”. TR 15504-2) • Objectives: • identify, plan and schedule QA activities • identify quality standards, methods and tools • identify resources and responsibilities • establish and guarantee independence of those.. • perform the QA activities • apply organizational quality management systems
Configuration Management • “The purpose of configuration management is to establish and maintain the integrity of the work products of a process or product”. • Objectives: • identify, define and control all relevant items • control modifications • record and report status • ensure completeness of items • control storage handling , release and delivery
Making a project a success • “There are NO Silver bullets “ • Here are 11 of them !!!
11 Silver bullets - Planning 1. Requirements engineering • documented • traceability 2. Task, cost and schedule determination based on requirements 3. Risk management, with • problem tracking 4. Incremental development
11 Silver bullets - control 5. Work packages with visible progress measurement - WBS, Work package specifications - Earned value tracking 6. Software metrics; - size, efforts, schedule, quality 7. Software configuration management 8. Software quality assurance and standards 9. Peer reviews ( walkthroughs and inspections) 10. Independent verification and validation 11. Software engineering assessments and capability evaluation
Wounding the software project Werewolf • Implement the 11 techniques above rigorously on a software IT project - every chance for success
