- 8. Main Scopes of SPM
- 9. Objectives: Define the scopes of SPM Understand what project managers worry about Define the phases of a software project Explain the factors of management Be conscious of that a project needs elaborative planning, supervision and control Identify stakeholders and their objectives Define the criteria of success Introduction to SPM
- 10. Unfortunately, projects are not always successful. Standish Group in the U.S. analyzed 13,522 projects and concluded that only a third of them were successful; 82 percent were late and 43 percent exceeded their budget. The reason for these project shortcomings is often the management of projects. Why is SPM important?
- 11. In dictionary definition, it emphases on -----Being planned activity Routine: one knows exactly what to do Exploratory: full of uncertainties and risks What is a project? Routine Uncertainty of Outcome Jobs Exploration Projects Most likely to benefit from prj management
- 12. The characteristics distinguish projects: non-routine tasks are involved; planning is required; specific objectives are to be met or a specified product is to be created; the project has a predetermined time span; work is carried out for someone other than yourself; work involves several specialism; people are formed into a temporary work group to carry out the task ; work is carried out in several phases; the resources that are available for use on the project are constrained; the project is large or complex. What is a project? The more any of these factors apply to a task, the more difficult that task will be.
- 13. Scope: What work will be done as part of the project What unique product, service, or result does the customer or sponsor expect from the project Time How long should it take to complete the project Who can approve changes to the schedule Cost What is the project’s budget Who can authorize changes to the budget Project Constraints
- 14. Invisibility: With software, progress is not immediately visible Complexity: Per dollar, software products contain more complexity than other engineered artefacts Conformity: Software developers have to conform to the requirements of human clients Flexibility: Software systems are particularly subject to change Software prj vs. other types of prj ICT Project – Information and Communication Technology Project
- 15. A software project is not only concerned with the actual writing of software. In fact, where a software application is bought in “of the shelf”, there may be no software writing as such, but this is still fundamentally a software project because so many of the other activities associated with software will still be present. Activities covered by SPM Feasibility study Plan Is it worth doing? Project excution How do we do it? Do it! Three successive processes
- 16. 1. The feasibility study: assesses whether a project is worth starting – that it has a valid business case. 2. Planning: If the feasibility study indicates that the prospective project appears viable, then project planning can start. 3. Project execution: The execution of a project often contains design and implementation sub-phases. Design is making decisions about the form of the products to be created. Planning details the activities to be carried out to create these products. E.g., Activities recommended in the international standard ISO 12207 Activities covered by SPM
- 17. Activity: test a component Methods: Real activates: A plan takes the method and convert it to real activities, identifying for each activity Groups of methods or techniques are often grouped into methodologies such as object- oriented design Plans, methods and methodologies Analyze the requirements Devise and write test cases Create test scripts and expected results Compare the actual results and the expected ones a plan Its start and end dates Who will carry it out What tools and materials
- 18. Compulsory vs. voluntary users Supermarket transaction system vs. computer game Information systems vs. embedded systems Office system vs. machine control system Objectives vs. products to meet certain objectives vs. to produce a product (course management system vs. anti- virus system) Some ways of categorizing software projects
- 19. The people who have a stake or interest in the project Internal to the project team External to the project team but within the same organization External to both the project team and the organization Identify them early for setting up better communication channels Stakeholders
- 20. Objectives focus on the desired outcomes of the project rather than the task within it. SMART principles Specific: Effective objectives are concrete and well defined Measurable: measures of effectiveness which tell us how successful the project has been Achievable: within the power of the individual or group Relevant: must be relevant to the true purpose of the project Time constrained: should be a defined point in time by which the objective should have been achieved Setting objectives
- 21. The project plan should be designed to ensure project success Project success can usually be summarized and delivering: the agreed functionality To the required level of quality on time within budget Project success vs. business success Project success and failure
- 22. Management involves the following activities: planning – deciding what is to be done; organizing – making arrangement; staffing – selecting the right people for the job; directing – giving instructions; monitoring – checking on progress; controlling – taking action to remedy hold-ups; innovating – coming up with new solutions; representing- liaising with clients, users, developer, suppliers and other stakeholders. What is management
- 23. Management, in general, involves setting objectives for a system and then monitoring the performance of the system. Management control
- 24. Using project management techniques provides advantages, such as Better control of financial, physical, and human resources Improved customer relations Shorter development times Lower costs and improved productivity Higher quality and increased reliability Higher profit margins Better internal coordination Positive impact on meeting strategic goal Higher worker morale Advantages
- 25. Projects are by definition non-routine and therefore more uncertain than normal undertakings Software projects are similar to other projects but have some attributes that present particular difficulties, e.g. the relative invisibility of many of their products. A key factor in project success is having clear objectives. Different stakeholders in a project, however, are likely to have different objectives. This points to the need for a recognized overall project authority. For objectives to the effective there must be practical ways of testing that the objectives have been met. Where projects involve many different people, effective channels of information have to be established. Having objective measures of success helps unambiguous communication between the various parties to a project. Conclusion
- 26. Section 1.16 Further exercises Exercises 3 A public library is considering the implementation of a computer-based system to help administer book loans at libraries. Identify the stakeholders in such a project. What might be the objectives of such a project and how might the success of the project be measured in practical terms? Homework
