The procedural standards may lay down the quality checks that need to be done at each point of the project life cycle or these may be documented in a separate quality standards and procedures manual. On the other hand, contingency plans specify action that is to be taken if a risk materializes. 4. So ware Quality 305 CMMI (Capability Maturity Model Integration) CMMI is the successor of the Capability Maturity Model (CMM). If all the topics are covered, students will be comfortable answering the question paper during the examination. 304 So ware Project Management Level 2: Repeatable Organizations at this level usually practise some basic project management practices such as planning and tracking cost and schedule. We noted back in Chapter 1 that with conventional project planning, it is not usually possible to plan all the phases of a project at the outset, as much of the information needed to produce the detailed plans will not be available. If estimates for costs, performance and service levels cannot be provided, then there should at least be an indication of how they might be measured; for example, one might be able to say that repeat business will be increased, even if the precise size of the increase cannot be provided. Belbin, R. Meredith, Team Roles at Work, Oxford, Butterworth-Heinemann, 1996. Where deadlines are tight, then either an evolutionary or an incremental approach is favoured over a one-shot strategy, as both tactics should allow at least something to be delivered at the deadline, even if it is not all that was originally promised. As a minimum, the normal stages in the software life cycle to be carried out should be documented along with the products created at each stage. One would have to evaluate the methods that the developers intend to use to see whether they adhere to good interface design practice. If developer A is available from the start of the project and developer B and C become available after three weeks of the start of the project. At present, the automation of these transformation processes is still being developed. At the end of week 3 she decides to keep to the existing targets. to his or her satisfaction. Allocating the most experienced staff sis might need to be to the highest-risk activities is likely to have the greatest effect in reducing carried out in parallel overall project uncertainties. Draw up quality specications in respect of the qualities of: usability reliability recoverability. XP refers to these as releases. Burmans priority ordering for allocating resources to activities takes into account the activity duration as well as its total oat. The tasks will be timed and any problems the subjects encounter with the package will be noted. The ideal is that you are constantly changing partners so that you get to know about a wide range of features that are under development. FIGURE 6.25 Another use of a dummy ac vity These are problems that do not occur with activity-on-node networks. For example, a new information system could be used to provide a customer service such as recording the details of people buying a new insurance product. Real data helps to focus discussions on most crucial issues during the postmortem review. Note that it is only the leaves of the structure that comprise the list of activities in the project higher-level nodes merely represent collections of activities. Candidates with the help of the notes can score better marks. Step Wise should be compatible with PRINCE2. In the second edition of his book, Beck favours iterations of one week on the grounds that people tend to work naturally in weekly cycles. This would be very costly and require the normal service to customers to be degraded. Each sprint typically takes only a couple of weeks. A key component of this is changeability, which is the ease with which the software can be modied. Software Engineering Concepts - Richard E. Fairley On the other hand, controlling too little might lead to confusion and inconsistency when something changes. Would you classify this as a product, process or resource risk? This reected Boehms nding that larger projects tended to be less productive than smaller ones because they needed more effort for management and coordination. A.8 Starting Up a Project As we noted in Chapter 2, the decision to undertake a project does not spring out With the rst version of PRINCE there were of thin air. The third step is resource allocation. Configuration librarians role Control of changes and documentation ought to be the responsibility of someone who may variously be named the conguration librarian, the conguration manager or the project librarian. There may be a mismatch between the planned outcomes Monitoring and Control 203 and the actual ones. 16. Among the decisions involving risks will be those allocated to technical experts such as engineers and ICT practitioners. But an analysis of any incidence of successful completion of a project would reveal the heroic efforts put in by some members of the project team. TORRENT download. Also, in some places there are shortages of qualied repair people leading to delays in getting work done. So ware E ort Estimation 115 The following model can then be used to calculate an estimate of person-months. Most managers resist very precise estimates of loss or of the probability of something occurring, as such gures are usually guesses. This is especially true for large and complex software products that are being developed currently. What can you infer about the current quality practices at the organization? 9.9 Prioritizing Monitoring So far we have assumed that all aspects of a project will receive equal treatment in terms of the degree of monitoring applied. Putnam adapted the RayleighNorden curve to relate the number of delivered lines of code to the effort and the time required to develop the product. Accumulating errors during software development As computer system development comprises steps where the output from one step is the input to the next, the errors in the later deliverables will be added to those in the earlier steps, leading to an accumulating detrimental effect. After three months, you realize that the project is 30% complete at a cost of 40,000. Where a core system has been customized by a supplier then there is less scope for the customer to insist on exclusive use. 8. 12.8 Communication Plans Communication is important in all projects but a vital matter in the case of dispersed projects. Someone already familiar with the software would be in the best position to do this. These can be set up in all departments of an organization, including those producing software where they are known as software quality circles (SWQC). A key PRINCE2 principle is to avoid too detailed planning at too early a stage. Step 5: Analyze the results di, i=1,n ; summarize and display using a histogram as the one shown in Figure 7.9. The general planning process PL is not shown as this can take place at various times and places for different reasons. A good problem size measure should consider the effort required for carrying out all the life cycle activities and not just coding. Imprecise requirements Uncertainties or a novel hardware/software platform mean that a prototyping approach should be considered. FIGURE 8.7 Amandas work schedule Resource Allocation 195 196 So ware Project Management FIGURE 8.8 Amandas revised precedence network showing scheduled start and comple on dates In general, costs are categorized as follows. Data-oriented We rst introduced the systems generally mean information systems that will have a substantial database. Thus, the heart of many projects is collaborative problem solving. In the following chapter on working in teams the research drawn upon tends to be more qualitative and based on case studies in the interpretivist tradition. Feasibility study This conrms that the benets of the potential system will justify the costs. distributed. Booch, Grady, Object Solutions: Managing the object oriented project, Reading, MA, Addison-Wesley, 1996. Although Boehm rejects them as prediction techniques, they have value as management techniques. Managing People in So ware Environments 255 Other procedures References will need to be taken up where necessary, and a medical examination might be needed. In convenChapter 4. tional software development projects, a typical approach to improving communication and coordination is to introduce more documentation. Brigette at Brightmouth College considers the application area to be very well dened. Appendix C Answer Pointers 371 Programmers could be encouraged to produce and publish reusable components by a system of royalties for each time a software component is reused. They are not sure, at the moment, that it can provide the kind of interface that would be needed and are also concerned about the possible response times of a system developed using Microsoft Access. The expected value of extending the system is therefore 40,000 (75,000 3 0.8 100,000 3 0.2) and the expected value of replacing the system 10,000 (250,000 3 0.2 50,000 3 0.8). Introduction to Software Project Management 1 2. Note that if the specication of module C were to be delayed for a further day, the project could be completed with only three analyst/designers, although its completion day would, of course, be delayed. The internet allows these contractors to carry out well-dened tasks at their own premises without necessarily having to travel to their clients site. (a) The number of error messages produced on the rst compilation of a program. Step 8.2: Document plans and obtain agreement It is important that the plans be carefully documented and that all the parties to the project understand and agree to the commitments required of them in the plan. On the other hand, it could turn out to be quite a considerable software modication task. Extreme programming is sometimes shown with a capital X i.e. What also needs to be agreed is when the payments are to be made. Moreover, the simple net prot takes no account of the timing of the cash ows. Even a failed project should not be viewed negatively. At the end of each sprint, stakeholders and team members meet to assess the progress and the stakeholders suggest to the development team any changes and improvements they feel necessary. The unavailability of these experts because application. Other difculties include: cial characteristics of software identied by Brooks, i.e. Ultimately this should be the Project Board or equivalent. We will return to this point later on in this chapter. FURTHER EXERCISES 1. A risk might be that key users are unavailable when needed to supply details of their requirements. The intention is to recruit someone who already has some experience. This book is for students of software engineering and computer science and also those studying business information systems.

If we go back to overall system specication and change it we can see from the PFD that all the products that follow it might need to be reworked. A reduction in the overheads that arise from having your own employees on site, including costs of accommodation, social security payments, training. FIGURE 4.4 Inten onal incremental delivery Selection of an Appropriate Project Approach 83 Time-boxing is often associated with an incremental approach. For this reason, it is very important for a project manager to make use of suitable tools. Each of these products is carefully dened. Some of these will almost certainly be about quality. In the network, time ows from left to right. One way of calculating this buffer is as the equivalent of 50% of the sum of lengths of the comfort zones that have been removed from the critical chain. Time constrained There should be a dened point in time by which the objective should have been achieved. Introduction and background This is a description of the current environment of the proposed project. A new version of a word processing package might read the documents produced by previous versions and thus be able to replace them, but previous versions might not be able to read all documents created by the new version. 216 So ware Project Management on time but has shown substantial costs savings. The bargaining position of the customer will be stronger if their business is going to be valuable. Predictable process 5. This scenario can be represented as a tree structure as shown in Figure 2.2. Each month a batch run of the system generates monthly statements for customers so that only one payment a month needs to be made. For every change that needs to be carried out, the CCB reviews the changes made to the controlled work product and certies certain aspects about the change such as Change is well-motivated Developer has considered and documented the effects of the change Monitoring and Control 231 Changes interact well with the changes made by other developers Appropriate people (CCB) have validated the change, e.g., someone has tested the changed code, and has veried that the change is consistent with the need The change control board (CCB) is seldom a group of people. That is, each team member takes on the role of the designer, coder, tester, etc., during the course of the project. EXERCISE 9.1 A software developer working on Amandas project has written the rst 250 lines of a Java program that is estimated to require 500 lines of code. Local (often about 60% of changes) Inspections are disThese change the way that a screen or report is processed but do not affect other cussed in Chapter 13. parts of the system. Making this broad assumption, a list of tasks and responsibilities might be as follows: carry out detailed investigations of new requirements for existing computer applications; analyse the results of investigations and review the solutions to problems experienced, including the estimation of relevant costs; prepare systems specications in accordance with organizational standards; conduct appropriate systems testing; prepare functional module specications; produce and modify module structure diagrams; code and amend software modules; carry out appropriate unit testing; produce and amend user documentation; liaise with users, carrying out appropriate training in the use of computer applications where required. However, significant opportunities may be lost by concentrating on th, Bob Hughes After a career spanning both industry and higher education, Bob Hughes is based at the School of Computing, Mathematical and Information Sciences at the University of Brighton, UK. This can be transformed into a platform-specic model (PSM) that takes account of a particular development and implementation environment. At the end of week 2, Brigette decides that obtain user requirements will not be completed until Tuesday of week 6 she therefore extends that activity line diagonally to reect this. Finally, the need to dene and agree the process by which completed Work Packages are handed over to the Project Manager is identied (MP3). However, this would cause the development cost to increase drastically. In a sales outlet, the number of sales staff does not usually vary with time. In consultation with the moderator, the project manager nominates the other members of the review team. The description in the exercise does not, for example, specify that the system should output a message that the car park is full or has spaces, although this might be expected. This stresses the necessity for validation activities that match the activities creating the products of the project. It estimates that there is a 1 in 10 chances of this happening. This happens to be very similar to the list given in Chapter 1. Sometimes, however, the implementation of ofce systems requires the creation of physical infrastructure which can have inherent physical dangers. This assumes that the targets are reasonable no account is taken of the possibility of project managers achieving record levels of productivity from their teams, but still not meeting a deadline because of incorrect initial estimates. The copies are modied. Activity Planning 126 7. The blueprint The achievement of the improved capability described in the vision statement can come only through changes to the structure and operations of the organization.

For the sake of clarity, the number of activities on a timeline chart must be limited. For not-for-prot organizations we would try to quantify the benets even if we cannot quote a precise nancial value. There may also be a period of warranty during which the supplier should x any errors found for no charge. The algorithms used might need to be repeatedly adjusted until they satisfactorily imitate real-world behaviour. They may, for example, do the analysis work for enhancements to existing systems but not of completely new applications. The exible use of staff they are not employed when they are not needed. 58 So ware Project Management This part of the planning process draws heavily on the standards laid down in PRINCE2. Activity Planning 129 FIGURE 6.1 Ac vity planning is carried out in Steps 4 and 5 6.5 Projects and Activities Defining activities Activities must be Before we try to identify the activities that make up a project it is worth reviewing dened so that they what we mean by a project and its activities and adding some assumptions that will be meet these criteria. The development team are all located in the same ofce and this leads to team cohesion being rated as very high, but the software house as a whole tends to be very informal in its standards and procedures and the process maturity driver has therefore been given a rating of low. Why is this not a top-down approach? The moderator plays a key role in the review process. It concedes that mapping external and internal measurements can be difcult and that validation to check that there is a meaningful correlation between the two in a specic environment needs to be done. . The database for the application contains the following data types: Staff reference Surname Forenames Title Department code Room number Telephone extension E-mail address Fax number Transactions are needed which: (i) set up new entries; (ii) mend existing entries; (iii) delete entries; (iv) allow enquirers to list online the details for a particular member of staff; (v) produce a complete listing of the telephone directory entries in alphabetical order. why, say, a Measurable Ideally there should be measures of effectiveness which tell us how 50% reduction in complaints and not 40% or successful the project has been. However, this should not be over-estimated as many analysis and design tasks have to be undertaken whatever the approach. This is increasingly so as organizations rely more on their computer systems and software is used in more safety-critical applications, for example to control aircraft. See Milton Friedman (1970) The social responsibility of business is to increase prots The New York Times Magazine 13 September. Debugging For each failure observed during testing, debugging is carried out to identify the statements that are in error. 13.8 Information flows for staff allocation When the architecture design process which creates work packages is taking place, there could be a further output, namely the effort estimation for each software component. For example, the SSADM Reference Manual provides a set of generic PBSs for each stage in SSADM, which can be used as a basis for generating a project specic PBS.
