unique challenges First, the test takers may nd preparation for the test a problem given the variation in tasks In addition, since the open-ended exercises allow candidates to consider and incorporate a wider range of practical information in their responses, response time can be lengthy, resulting in limited numbers of tasks within a given period of time Further, the amount of time required to respond can vary dramatically across exercises In the worst case, the response information collected from the test taker is too sparse to produce a reliable score These assessment tasks, while they have substantial relevance to practice, limit the breadth of content that can be covered in a given amount of time, thus threatening the generalizability of the interpretation of the results and the comparability of scores across examinees In addition to the variability in content and item type current test development procedures often do not constrain examinee responses suf ciently to prevent test takers from providing unique and unexpected, but correct, responses The creative test developer may not (and probably can not) envision every behavior candidates will evince These issues might be viewed as a natural tension between the need to present realistic exhibits, and the desire to collect as much pertinent response data as possible from the candidate in a restricted time period However, responses to realistically complex tasks can lead to a need to engage in lengthy, error-prone manual review of arge numbers of unanticipated responses to tasks An emerging alternative, described elsewhere in this volume ( 5), is that of principled design A principled design process is intended to focus the test developer s creativity on the key assessment goals of an exercise while limiting the introduction of irrelevant variation in the tasks Principled design begins by considering the interpretation of the score and keeps that perspective paramount in task design and content development A series of questions illustrates how the sequence of the development process would be changed from the standard blueprint-based approach: What conclusions do I want to draw about the test taker s knowledge and skills What would constitute evidence that the test taker has or does not have that knowledge and skill Can I ask the test takers to give an answer or perform a task that would require them to provide the evidence I seek What static and/or interactive information will the candidate require (eg description of client or patient situation, relevant nancial or medical information, etc) What tools (eg spreadsheet, word processor, and calculator) are required for the candidate to provide the information and how robust do these tools need to be Is there any non-relevant knowledge or skill required to answer the question or perform the task Can I develop many different questions to measure this task that are equivalent .

Do the questions provide suf cient information for the time it takes the test taker to respond, and leave time so that I can ask more questions to ensure con dence in the decision made using their scores Can I evaluate the responses consistently, quickly, and accurately By following the principled design sequence, test developers become more than subject matter experts They now participate in the realm of test engineers and software architects The answers to the questions above should provide the speci cations for assessment task design Among the speci cations that can result from a principled design are the tools (exhibits, calculators, spreadsheets, word processors, search engines, etc) that need to be available to the test taker to provide the necessary information, limitations on the length of the task based on the amount of information to be generated from it, the range, breadth, and depth of content that is appropriate for the task, and the rubrics, keys, and rules to evaluate of the response (single key, lists of acceptable keys, algorithms, etc) In other words, principled design will produce assessment templates that both enable and constrain test development A principled design can also provide standardized speci cations for the tools For example, there may be suf cient overlap across different nancial situations that several entire classes of tasks can all be supported by one, two, or three standard spreadsheet templates Properly designed, these templates would be large enough to allow the creation of useful measurement tasks, but would ensure that the test developer does not ntroduce unnecessary and time-consuming complexity into the task Bene ts from this design process should be decreased complexity of task development, increased quality and consistency across tasks, which aids both the developers and the candidates, known task characteristics (eg unidimensional or multidimensional), known response characteristics, comprehensive scoring speci cations, and reduced costs of both development and scoring An important intended longer-term bene t from a rigorous principled design is the development of tasks with known statistical properties Once the features of the task have been stabilized and the essential format of the item or task has been administered to test takers, the empirical dif culty of scored elements can be estimated An example of the usefulness of collateral information in the prediction of statistical properties of new items is available from Keller (2002) These estimates could be useful in scoring (or calibration with smaller samples) when new tasks are based on the same template Such a result would dramatically reduce the time between the development of a task and its use in an operational test (by eliminating the need for pretesting or post-administration analyses) and allow faster scoring and reporting Additional bene ts of a principled design include automated, or semiautomated, task generation and review, thus further reducing development time and expense (see, eg, Brittingham et al, 2000) In order to meet consumer needs, performance exercises of the future will need to measure a combination of skills and content, be template based, and.

At the basic level, there s nothing special you d do for a software package or a set of developer libraries as pposed to taking an intraday checkpoint of a mail spool or a home directory. The following are a few more rules to live by:. EAN 128 Encoder In .NET Using Barcode encoder for .NET . Consider how you build up a directory in which local tools, libraries, manual pages, and ther locally important files reside. The standard approach is to have one tools directory on a large file server that all clients share; changes are made to the file server, and all of the clients see them within a short window. Note that the quick-and-dirty method introduces a SPOF at the file server and isn t scalable for performance. If your client load is going to increase over time, you ll need to be able to crank up the horsepower of the tools directory server at the same time, and that means multiple copies of it, close to where its users are on the network. The single tools directory also leaves you open to process weakness in change management. What if your latest software installation has a broken install script and trashes the tools directory With replication and change management you have built processes to recover from internal corruption. Test a new or modified tool by building a new area within the shared directory, verifying operation using the master, and then pushing the replication to the slave servers.Related:

The rst task in the planning meeting was to clear the board and count the point value of the cards completed in the previous iteration This was recorded and used as a guide for the coming iteration s capacity The team could accept slightly more points into the iteration than had been completed in the previous week on the understanding that some might not get done With blue cards and white cards prepared and our estimate of the work that could be done, the product manager would prioritize all the white cards Developers would advise of any dependencies between cards, risks, opportunities and suchlike, but prioritization was the product manager s decision alone All cards were prioritized in absolute order, so that it was clear which one was the top priority and which the last No two cards were allowed the same priority Once prioritized, they would be placed on the board in the work to do queue Each day, the team would hold a short stand-up meeting and select the cards they would work on from the to do queue Some developers would choose to pair on some work, but we didn t pair all the time If work was completed without pairing, it would be subject to a short desk-based code review before checking into source code control Developers tried to write unit tests for the new features However, due to the existing legacy code base this wasn t always possible There were no unit tests for code that already existed, so refactoring existing code was dif cult All unit tests were run each night after the nightly build was completed Should the build or any tests fail, the whole team received mail and the rst person in began to investigate the failure Each team had a software tester, who was responsible for accepting a completed white card When the developer felt that a card was complete, it would be moved to the waiting for test column on the whiteboard and the developer would take nother card Only when the tester was satis ed that the work was completed would it be marked and moved into the completed column Testers had a variety of ways of testing cards: they could perform a manual test, they might ask to verify that the unit tests were working and they might ask for proof that the code had been reviewed If they were not satis ed, or a defect was found, then the card would move back to the in progress queue, with a high priority Finally, if a fault did slip into the system, or was reported by another team and was added to the team s workload, it would be written up on a red card Red cards automatically took priority as the next piece of work to be started Unfortunately, the nature of the system meant that it was dif cult to eliminate such tasks, but over time the number did fall Several projects successfully used this process and each team modi ed it in different ways No team was able to eliminate all manual testing,.
