Demonstrations might not reveal this problem. Project A is therefore a closer analogy. These kinds of risk need a contingency plan. If, over time, staff become aware that the targets set are unattainable and that projects routinely miss targets, motivation is reduced. Paul has to phone both the human resources manager about getting a replacement and the user for whom the less urgent work is being done, explaining why it is likely to be delayed. For the objectives, identify the measures of effectiveness. It can be argued that all projects should be included in the ofcial portfolio. This is, of course, not very surprising since it tells us that if the project does not start on time it wont nish on time. 8.10 The Scheduling Sequence Going from an ideal activity plan to a cost schedule can be represented as a sequence of steps, rather like the classic waterfall life-cycle model. Automated Test Script Test scripts are used to drive an automated test tool. This would be very time-consuming. This could include nancial reports, references from past customers and the CVs of key development staff. In English law, with certain exceptions, a contract does not have to be in writing. First is an objective-driven project resulting in recommendations. It also reects Tom Gilbs concern that system developers always keep sight of the objectives that they are trying to achieve on behalf of their clients. Be careful about using other peoples historical productivity data as a basis for your estimates, especially if it comes from a different environment (this includes COCOMO). Read all the topics carefully and prepare for the Software Engineering examination properly. It might be thought that organizations have greater ethical responsibilities given their greater power to inict damage than individuals, particular when they implement large development projects of various kinds. Health Professions These are some of the activities in which use of automated tools can be of great help. Now identify risks for each scenario that relate to pairs of domains, for example ActorsTechnology, ActorsTasks, and so on. Some changes to the plan might have an impact on the delivery date, project scope or costs. In such a situation, unless a proper conguration management system is deployed, several problems can appear. They perform these activities again and again for different projects, and thereby gain experience and insights into their respective areas of specialization. For example, as software development proceeds, more software is created, and more time would be needed to re-create it if it were lost. 13 A good introduction to the issues discussed here can be found in A. J. Shenhar and O. A common error is to identify as products things that are really activities, such as training, design and testing. In Figure 7.2 all boxes are interlinked. Integration testing is one mechanism that ensures that these requirements are met. In this scenario, this has to wait until the completion of Project A because that project has examined how the two sets of applications for the previous organizations could be brought together, and this has repercussions on the departmental structure of the new merged organization. Programme management is often used to coordinate activities on concurrent jobs. The effort needed to implement different design proposals will need to be estimated. For example, if the estimated development time using COCOMO formula is one year, then in order to develop the product in six months, the total effort required (and hence the project cost) increases 16 times. Think carefully about how to handle the costs of Amanda as project manager and the recovered overheads and justify your decisions about how you treat them. The principle is that normally developers should not work more than 40 hours a week. Once the system seems to be satisfactory to the developers, it is released to the Systems Testing Group for nal testing before shipping to customers. Testing english as a second language : Harris, David P : Free Download It is rare that this convention needs to be outed but some people add arrows to the lines to give a stronger visual indication of the time ow of the project. There might be decommissioning costs at the end of a products life. Fiona is a nal-year computing undergraduate student who in her third year undertook a placement with the ICT department of an insurance company as a support analyst and then a network manager. Note that these are not usually iterations in the sense that they are new, improved, versions of the same feature although this is a possibility. It differs by focusing on the physical features of the application, such as screens and reports, rather than logical ones such as entity types. PDF Lecture Notes - MREC Academics The factors to be taken account of could include costs and human factors. Amanda has therefore included additional ofce space as a possible requirement, should contract software development staff be recruited. While the setting of objectives involves identifying the problems to be solved, this part of planning is working out the ways in which these problems are to be solved. In this case transaction time would be affected by hardware and software performance as well as the speed of human operation. Explain Information retrieval system strategies. This is where the additional effort required to create automated test scripts can pay off. In general, try to make activities about the length of the reporting period used for monitoring and controlling the project. l Assess the size of the buffers. Highlighting Specic Activity Attributes Using the different patterns and colour for different activity attributes, a project manager can highlight important aspects of the project. What problems are you likely to face if you are developing several versions of the same software product according to a clients request and are not using any conguration management tools? The RAD approach does not preclude the use of some elements of structured methods such as the drafting of logical data structure diagrams but also adopts tactics such as joint application development (JAD) workshops. The management of safety should therefore be embedded in the general management of the project. There is therefore a risk that they may take longer than expected to modify. . An expanding area of their work is the maintenance of ICT equipment. The plan details the activities to be carried out to create these products. A natural concern would be the standard of the contractors deliverables. For example, if there are two or more shapers within a group and nobody who takes a chair role to moderate conicting views, there is likely to be a stormy atmosphere. It is agreed that some kind of pilot to evaluate the scheme is needed. tata-mcgraw-hill-ntse-class-10 6/19 map index pdf with CAT Test for quick revision of concepts 4. What is the oat time of the task T4? We will return to this point later on in this chapter. If we expect individuals as individuals to be socially responsible and ethical, then when these individuals are also shareholders we might expect them to be socially responsible in that role as well. A detailed plan for the project, however, must also include a schedule indicating the start and completion times for each activity. (The W stands for winwin.) The uncertainty surrounding estimates of future returns lowers their real value measured now. 1.8 Some Ways of Categorizing Software Projects Projects may differ because of the different technical products to be created. Customer relationships can also be built up over a number of projects. Compute how many of these defects would survive after the processes of code review, unit, integration, and system testing have been completed. Staff, particularly those with less experience, could respond to pressing deadlines by producing work that is substandard. Some of the challenges of dispersed working are: The requirements for work that is distributed to contractors have to be carefully specied. When a vehicle leaves the car park, a sensor detects the exit and reduces the count of vehicles. 2. The workers were then trained to do the work in this way. It is likely, however, that the kinds of analysis tasks undertaken will be restricted. Draw up a Product Breakdown Structure, a Product Flow Diagram and a preliminary activity network for the above. It is convenient to think of a conguration as a set of les representing various work products. 5. Any delay to any activity on this critical path will delay the completion of the project. A very carefully judged increase in task-oriented management will be required for a short time. The activity description will normally be a brief activity name such as Test take-on module. 3. Another task will be system conguration there are a number of parameters that will have to set in the application so that it runs satisfactorily for Brightmouth College. However, because social systems, including business organizations, are so complex, it is not possible to predict their outcomes with any certainty. . Thus one statement in a set of objectives might be customers can order our products online rather than to build an e-commerce website. Risk We saw how to undertake activity risk assessment in the previous chapter. Quoted by Wanda J. Orlikowski in Groupware & Teamwork, edited by Claudio U. Ciborra, Wiley and Sons, 1996. Fact-nding, for example, might be speeded up by allocating an additional analyst to Monitoring and Control 223 interviewing users. Researchers and innovators in the area of computerSamus Gallagher supported cooperative work (CSCW) have been interested in identifying the types of (2004) Communication and co-ordination coordination where computer tools could be of assistance. Microsoft Excel, for example, provides IRR functions which, provided with an initial guess or seed value (which may be zero), will search for and return an IRR. TABLE C.10 Calcula ng expected ac vity dura ons Activity Activity durations (weeks) Optimistic (a) Most likely (m) Pessimistic (b) Expected (te) A 5 6 8 6.17 B 3 4 5 4.00 C 2 3 3 2.83 D 3.5 4 5 4.08 E 1 3 4 2.83 F 8 10 15 10.50 G 2 3 4 3.00 H 2 2 2.5 2.08 362 So ware Project Management 7.8 Calculating standard deviations The correct values are shown in Figure 7.7. Methods often involve the creation of models. The state of all work products at any point of time is called the conguration of the software product. Design Change Analysis: Identify the design parts of the pay roll software that would not be needed, be excluded, changed, and the ones that would have to be developed again. 174 So ware Project Management When Monte Carlo simulation is used to analyse the risk of not meeting the project deadline, the project completion time is rst modelled as a mathematical expression involving the probability distributions of the completion times of various project activities and their precedence relationships. Unfortunately, the application that had been bought did not allow such access. The application will allow employees to make suggestions about process improvements, and will track the subsequent progress of the suggestion as it is evaluated. Boehm and R. Ross, Theory W software project management: principles and examples, in B. W. Boehm (ed.) Its disadvantage as a selection technique is that it ignores the overall protability of the project in fact, it totally ignores any income (or expenditure) once the project has broken even. A tool can also help a project manager effectively and efciently develop various charts such as GANTT and PERT charts. Put them into an order most closely matching your ideas of what constitutes a project. Risk Management 157 FIGURE 7.1 Risk planning is carried out primarily in Steps 3 and 6 7.3 Categories of Risk An ICT project manager is normally given the objective of installing the required application by a specied deadline and within an agreed budget. Sprints are time-boxed and at the end of the sprint period some uncompleted, lower-priority features may be held over. . single project team, provides an effective vehicle for communication and coordination among teams.

We have explored some of the special characteristics of software. To be able to decide upon a suitable tool to use for a specic project, it is necessary for a project manager to have an understanding of the features supported by different tools. EXERCISE 12.2 What developments in information technology would be of particular assistance to use of the Delphi technique? T3 can start when T2 is complete. 2. Therefore, in order to optimize the turnaround time, the test failure information is usually informally intimated to the development team as and when failures are noticed. This is followed by the general steps to be followed when placing a contract. Having calculated the overall effort required, the problem is then to allocate proportions of that effort to the various activities within that project. Two software components with the same opted see Software KLOC will not necessarily take the same time to write, even if done by the Size Measurement: same programmer in the same environment. It is not comprehensive but illustrates some of the types of items that you should have listed. For example, if a specialist is needed it would make sense to advertise in the relevant specialist journal. The incremental approach encourages the execution of a series of small, manageable, mini-projects but does have some costs. The rst developer is under a lot of pressure from the client to complete the work. So ware Quality FIGURE 13.5 315 The V-process model Using the V-process model as a framework, planning decisions can be made at the outset as to the types and amounts of testing to be done. Objectives focus on the desired outcomes of the project rather than the tasks within it they are the post-conditions of the project. A danger is that demonstrations can be controlled by the supplier and as a passive observer it may be difcult to maintain full attention for more than, say, half an hour. What would be the total charge according to the schedule in Table 10.1? Once resources have been allocated to each activity, we will be in a position to draw up and publish a project schedule, which indicates planned start and completion dates and a resource requirements statement for each activity. A feasibility study might decide that the implementation of a proposed system would be benecial. Discussion points might be: (a) The developer might not be familiar with the context of the application domain for example the terminology employed by the users. This makes it important for organizations to take a broad view of all its projects to ensure that while some projects may disappoint, organizational developments overall will generate substantial benets. What work would be involved in deleting functionality that could justify this cost? As soon as the activities along a particular path use up their total oat then that path will become a critical path and a number of hitherto non-critical activities will suddenly become critical. This edition can be exported from India only by the publishers, Tata McGraw Hill Education Private Limited ISBN-13: 978-0-07-107274-8 ISBN-10: 0-07-107274-8 Vice President and Managing Director McGraw-Hill Education, Asia Pacic Region: Ajay Shukla HeadHigher Education Publishing and Marketing: Vibha Mahajan ManagerSponsoring: SEM & Tech Ed. Some of these human considerations affect staff as individuals. Explain why it would be unreasonable to assume that the programming task is 50% complete. Horizontal All features are prototyped but not in detail perhaps there is not full validation of input. In fact, benets are often inter-linked. Earned value may be measured in monetary values but, in the case of staff-intensive projects such as software development, it FIGURE 9.11 Amandas baseline budget 218 So ware Project Management is common to measure earned value in person-hours or workdays. 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. A key element of this would be ensuring that the contractor had the right quality management system in place. Within the general heading of management meetings there could be a range of types of meeting each with their own conventions. The possibility that an assumption upon which a plan is based is incorrect constitutes a risk. It is therefore, potentially, very misleading. Online Learning Centre This book is supported by the following additional study resources for both instructors and students. Documenting amendments may take place alongside prototype testing so long as it starts at least one day later and nishes two days later. 80 days, while Ken, who is less experienced, would need 55 days per KLOC and take 2 3 55, i.e. Since the chief programmer carries out many tasks individually, there is a danger of information overload on the chief programmer. Suppose that, in a particular project, it is necessary to specify a certain piece of hardware before placing an order for it and before coding the software. Though democratic teams are less productive compared to the chief programmer team for small and simple projects, the democratic team structure is appropriate for less understood problems, since a group of developers can invent better solutions than a single individual as in a chief programmer team. For the document transfer aspect, the following might be usefully collected for each ofce on a regular basis during the transfer process: number of documents transferred; estimated number of documents still needing to be transferred; number of staff-hours spent on transferring documents to monitor the budget and transfer productivity; number of staff involved in the transfer. Using the method described above, calculate the Albrecht function points for this subsystem assuming that the report is of high complexity, but that all the other elements are of average complexity. Before we can do this, we must consider what resources will be required and whether or not they will be available at appropriate times. Established process 4. Point out the main steps that you would follow to effectively manage risks in your project. Quantitatively managed Organizational process performance, quantitative project management 5. This might require a brainstorming session involving the whole project team or it might stem from an analysis of similar past projects. This will affect the way projects are conducted. It is important, however, to be aware of the major shortcomings of the SLOC measure. Brainstorming might be used with Brigettes Brightmouth payroll implementation project as she realizes that there are aspects of college administration of which she is unaware. risk reduction leverage = (REbefore REafter)/(cost of risk reduction) REbefore is the risk exposure, as explained in Section 7.6, before risk reduction actions have been taken. It has often faced difculties dealing with the quality of performance of vendors, to whom it So ware Quality 303 assigned contracts. Such transfers would be made easier if: Appendix C Answer Pointers 361 there was a standard methodology for the way that the work was carried out; intermediate steps were well documented; other staff were involved in reviewing products at regular intervals; job descriptions were exible. Not many software books have lasted as long as this one. Verication techniques can be viewed as an attempt to achieve phase containment of errors. The requirements document issued to potential suppliers would also contain requests for information needed to judge the standing of the organization itself. Most of those working at home reported that they were more productive. A specialized list of software development risks by Barry Boehm appears in Table 7.1 in a modied version. Various national and international standards bodies, including the British Standards Institution (BSI), have engaged in the creation of standards for quality management systems. Inexperienced staff will take longer to carry out development in any case. The moderator plays a key role in the review process. Hardware environment The environment in which the system is to operate could put constraints on the way it is to be implemented. 156 So ware Project Management 7.2 Risk PM-BOK stands for Project Management Body of Knowledge, a project management standard published by the Project Management Institute in the USA. The boxes that are higher up for example module products are simply the names of groups of items. Typically, an ICT department has pools of particular types of expertise, such as software developers, database designers and network support staff, and these might be called upon to participate in a number of concurrent projects. The nal step is schedule production. However, requesting partial completion estimates where they cannot be obtained from objective measures encourages the 99% Many organizations use standard accounting systems with weekly timesheets to charge staff time to individual jobs. 226 So ware Project Management 7. Figure 6.16 illustrates our network after carrying out the backward pass. B.W. Among the agreements overseen by the WTO is one on government procurement which lays down rules on tendering processes. The term maintainability has been used, for example, to refer to the ease with which an error can be located and corrected in a piece of software, and also in a wider sense to include the ease of making any changes. For example, an organization might mandate the use of a particular development method. It should be noted, however, that Step Wise covers only the planning stages of a project and not monitoring and control. FIGURE 9.7 The slip chart emphasizes the rela ve posi on of each ac vity The timeline One disadvantage of the charts described so far is that they do not show clearly the slippage of the project completion date through the life of the project. In these circumstances, each iteration should be treated as a project in its own right. For almost four decades, Software Engineering: A Practitioner's Approach (SEPA) has been the world's leading textbook in software engineering. An insurance company has examined the way that it settles house insurance claims. A framework dictating the number of levels and the nature of each level in the structure may be imposed on a WBS. With some risks, there could be not only damage but also gains. The advantages of such an approach include: the supplier of the application can spread the cost of development over a large number of customers and thus the cost per customer should be reduced; the software already exists and so it can be examined and perhaps even trialed before acquisition, there is no delay while the software is being built; where lots of people have already used the software, most of the bugs are likely to have been reported and removed, leading to more reliable software.
