Progress tracking is a project management task, but it has specific effects in software projects. In this case it was the first time software people had to get used to metrics and that they draw some benefit out of it. The critical success factor is to link software quality assurance to progress reporting. A task is no longer finished when the planned effort had been spent. We want the deliverables resulting from that task be reviewed and approved. Based on that data we track actual duration and effort spent in projects and compare with plans. The effect is surprising: software projects suddenly behave “normal”. Teams stay focused on the planned tasks and keep to the deadline. Although bad effort estimation cannot be completely avoided, it is detected in the very early stages of the project. Delivery rates become apparent from the beginning.

Especially in the ICT industry, but as well for banking and pharmaceuticals, the need to exchange international experts is apparent. In many other aspects of economical life, having the ability to transfer experts from one country to another is decisive for the attractiveness of a site. Thus setting up a web site that allows applying for a work permit through the Internet and – if the application is all– inclusive for the needed documents and the applicant fulfils the law’s requirements – issuing the permits instantly is a major competitive advantage. The Project The trouble started at the very beginning. Having no expertise in setting up a project, the government department hired a consulting company to write an invitation to tender. This document did not mention project methodology or project management at all. Thus it was not required, and no details specified, therefore the government department had no means of discrimination. A large consulting company won the contract and subcontracted several specialists for creating software and setting up the service on the Internet. The same system was to provide workflow support for the civil servants of the several agencies involved in the review and approval of the applications. Using the same data for external and internal users, the system should maximize effectiveness. However, despite allocating around 30% of the total price for project management, the consulting company was not able to provide a skilled project manager. The first holder of the position left the project within the first two months, the second tried to manage the project by hiding the relevant information. There was no project plan, no project organisation, no roles and responsibilities, and for sure no quality management or quality plan. All he had was a Gantt chart, mentioning activities lasting two to three month, by a total planned project METRICS FOR PROJECT MANAGEMENT V10.DOC Copyright © 2003 Euro Project Office Page 5 of 15 UKSMA Conference Wolverhampton Metrics for Project Management Publication Dr. Thomas Fehlmann Version V1.0-13, 23 September, 2003 duration of about seven month, and a To-Do list that an impressing tendency to grow in size. Thus the project went the way all such projects must go: It hardly made the first milestone, already with a long list of To-Do’s, and completely missed the second. The author remembers his first project steering meeting where the project manager stated that one of these three-month tasks is “98% finished”. The author remarked that, when this statement had been true the day before the meeting, this task must have been finished by this very afternoon. Obviously it was not. In reality not even the hosting was prepared, and the software was buggy and very late. The Dilemma Obviously this was not state–of–the–art project management. The contract did stipulate, but not substantiate project management. It did neither mention a professional (PMI) certificate, nor any specific project management method. When the author joined the project and proposed to use progress metrics to the supplier, he did not accept the suggestion because it was not foreseen in the contract. For the government department, there was no other way than to insist on the schedule as stated in the contract but they had to let the supplier decide how to meet its obligations. All they could do, and what they did, was to spend additional money for a second project manager who should take over after completion of the contract, and for independent testing, to avoid having to rely on the supplier’s testing records. We had to endure another three missed milestones before the supplier finally admitted that the delivery date had passed and the contract failed. METRICS FOR PROJECT MANAGEMENT V10.DOC Copyright © 2003 Euro Project Office Page 6 of 15 UKSMA Conference Wolverhampton Metrics for Project Management Publication Dr. Thomas Fehlmann Version V1.0-13, 23 September, 2003 The Approach Taken The Taskforce Thus the government department installed a taskforce to take over and lead the project to its goal. The primary objective was that the supplier finished the delivery of the web application as soon as possible; thus it was not an option to stop the project. So how do you deal with people from whom you depend and who can listen neither to you nor to common lore nor even simply to good reason? The Six Step To Completion – Metrics The answer was a very simple metrics that was so simple those people from the supplier did not even understand that it is a metric indeed. We started with a To-Do list because that was a terminology people could follow. However, each of the To-Do’s was connected to a distinctive deliverable, as every project manager does with tasks in his project plan. That deliverable uniquely identifies the To-Do and gives objective evidence for completion of the task. Professionals with an auditing background understand the term “objective evidence”. Instead of arguing if the task or To-Do had been completed or not, the evident status of the deliverable tells us without asking people’s opinion. Figure 1: The Six Step To Completion Model for Measuring Objective Evidence Input Assignment Assignment Template Template Idea Idea Draft Draft Output 10% Draft Draft version version 30% METRICS FOR PROJECT MANAGEMENT V10.DOC Copyright © 2003 Euro Project Office Review Review Finalization Finalization Review Review report report 15% Page 7 of 15 20% AppApp Approval roval Release Release Operations Operations Distribution Distribution 15% 10% UKSMA Conference Wolverhampton Metrics for Project Management Publication Dr. Thomas Fehlmann Version V1.0-13, 23 September, 2003 Integrated Quality Assurance All we need is to provide a project repository where to post draft versions, review reports, released versions, and evidence for operational use such as distribution lists for documents and build logs for software. We use the Six Steps to Completion – model to measure progress based on objective evidence for completion for each of the six steps. The idea stage accounts for 10% of the total completion metric; the draft stage for another 30%. Then comes the review stage with 15%, the finalization stage with 20%, approval gives 15% and when put into operational use the last 10%. The last stage is equivalent for making the deliverable available for developers who have to rely on it and does not necessarily refer to the end users. Progress Metrics for Consensus Build-up Originally these percentages were just a guess. However, in the very first project where such completion metrics had been used (1999) we discovered that these percentages correspond quite neatly with the total task duration (not the effort!) such that we started using the completion percentages for Gantt chart tracking. The percentage values set forth in Figure 1: The Six Step To Completion Model for Measuring Objective Evidence seem to fit pretty well for creating documents, preparing workshops, training, or writing software. Thus, completion rates give an accurate estimate for the actual task duration. For example, if the completion rate is 40%, it means that we still need 60% of the total duration, i.e. 1 ½ times the duration that had already passed. If that was not foreseen by the project plan then you better update the plan right now to make it consistent with reality and manage expectations. Only tasks such as meetings – with the minutes as deliverable – and testing may have somewhat different percentages. We have since 1999 a record of around forty projects in a dozen different organizations that followed the same pattern with a variation below ten percent. The grading of the steps varies in nine degrees between “just begun” and “completed”. Thus it is possible to acknowledge work in progress within the Six Stages To Completion. Also it often happens that review or testing activities and finalization go in parallel, thus the familiar pattern of two green stages followed by two yellow ones, see the last line in Figure 3: Sample Progress Track with Issue History. More questionable it is when deliverables are already in use while still under finalization, but it happens too, e.g. in object-oriented development. The benefit of completion metrics based on reviews and approvals is that they reflect the degree of consensus reached for the deliverables. Reviews and finalization work still going on, or missing approvals clearly indicate missing consensus about the delivered results. Thus progress metrics are very important for management. This worked well in the e-Government project. METRICS FOR PROJECT MANAGEMENT V10.DOC Copyright © 2003 Euro Project Office Page 8 of 15 UKSMA Conference Wolverhampton Metrics for Project Management Publication Dr. Thomas Fehlmann Version V1.0-13, 23 September, 2003 The Successful Outcome The Effects of Visualization You never forget when the supplier’s project manager first noted that his To-Do, which he thought having finished by “85%”, counted only for some 30%. The taskforce met then weekly in a room with the actual Six Steps To Completion displayed prominently at a wall. There was not a single date missed. And interestingly: even the taskforce cost remained within budget. Why This Works Obviously this was more than just a psychological trick. The reason is very simple: The Six Steps To Completion represents nothing else than ordinary quality planning. Every serious Quality Plan must provide exactly that: a reviewing method and an approval procedure for every single deliverable in the project. Often quality planning is done at the beginning of the project (although not in this instance) but then not executed because of other priorities shovelling up. The effect of such missing quality assurance is not felt immediately, in contrary. It might even felt favourably for the moment because the QA resources are now free to do even more draft development. This seemingly positive experience will then be iterated again and again until it is too late and the quality problems start becoming apparent. Exactly that happened in the early stages of the e-Government project, and was the reason why the supplier’s people were not able to listen. The Six Steps To Completion – metrics makes this impossible. It short-circuits the quality plan to the project plan, or in this case, to the To-Dos. The team silently agrees on the necessary quality assurance being done at the root, causing significantly less bad surprises later on. The web site www.workpermits.zh.ch went on-line 20 February 2003, three months late with regard to the original schedule, but three weeks earlier than expected in the revised schedule after the taskforce took over. All To-Dos including all the quality issues discovered earlier were resolved, the hosting strategies established, and the site started to receive very excited feedback. METRICS FOR PROJECT MANAGEMENT V10.DOC Copyright © 2003 Euro Project Office Page 9 of 15 UKSMA Conference Wolverhampton Metrics for Project Management Publication Dr. Thomas Fehlmann Version V1.0-13, 23 September, 2003 Tools And Methods The Project Database Since 1998, Euro Project Office AG developed a tool1 based on MS–Project and Excel to integrate the Six Steps To Completion – method into project planning. It was developed and refined during the sequence of projects that the Euro Project Office supported. The basic philosophy was usability. This included the need to let the project manager use his tool without any restriction. This led to the solution to use the database of MS–Project to store all relevant project data, such as deliverable specifications, quality planning, quality records, and issues, on top of the data already present in MS–Project such as planned and actual schedule, planned and actual effort and cost, resource allocation and usage. All the MS–Project functionality is thus available but with significant enhancements. As already explained, the completion rates collected by the tracking process become in turn available again showing the actual completion percentage of the planned tasks. Visualization using Excel The choice of Excel for visualization makes it possible to easily adapt more functionality and analyze the project for later improvements. Excel as GUI is possibly not the best choice, but using VBA and the (loop-free) formula programmability of Excel allows for fast implementation at a high Function Points2 (FP) delivery rate. We make more than one FP per hour, or about six times more than Java or C++. Such a delivery rate outperforms some of the shortcomings of VBA. 1 The tracking software is Open Source and can be found in the /ch/open project methodology (www.ch-open.ch, or www.swisma.ch). However, since it is embedded in MS Office, it does not install without proper support, and is not self-explanatory. At least, you need training, and you need a project office to run the tool. 2 Unadjusted Function Points according IFPUG 4.1 METRICS FOR PROJECT MANAGEMENT V10.DOC Copyright © 2003 Euro Project Office Page 10 of 15 UKSMA Conference Wolverhampton Metrics for Project Management Publication Dr. Thomas Fehlmann Version V1.0-13, 23 September, 2003 The available Excel reports include Management overview of overall progress Specifications for each deliverable in the project Progress Track including issues per deliverable Quality Plan per deliverable Quality Records and access to deliverables Pricing per deliverable Test stories per deliverable Summary test results Efforts planned and actual per deliverable and per resource Summary planned and actual efforts per deliverable Progress data per project phase Costs and earned value per project phase Costs and earned value and expected trend per accounting period Planned Completion 32% Ap pro v 38% 34% 26% Schedule Trend Re ad y 41% 10% Fo rU se 15% al 20% Fin ali za tio n 30% 15% Re vie w Completion Rate 30% Dr Management Overview 10% Ide a Weight 25.

Because it is based on object evidence, such reports can be generated by the project office and need but comments by the project manager. Thus it replaces administrative work by a service, and saves cost in the project.

Data Capture with Personalized Tickets The progress-tracking tool is not only integrated with the project repository, but also with the reporting process of each team member. Every team member gets his own personalized ticket, either via the Intranet, the project home page or any other suitable communication tool (including paper). The tickets integrate all of the reporting needed in a project, including time reporting. 1 Contact Triloga AG, Lucerne, Switzerland; www.scodi4p.com 2 Contact GMC Software Technology, www.gmc.net METRICS FOR PROJECT MANAGEMENT V10.DOC Copyright © 2003 Euro Project Office Page 12 of 15 UKSMA Conference Wolverhampton Metrics for Project Management Publication Dr. Thomas Fehlmann Version V1.0-13, 23 September, 2003 Figure 4: Sample Personalized Ticket 2.1.1 Clickable Prototype Dev2; Dev3; 14-Nov-02 01.

Instead of distributing and collecting electronic tickets, a wallsized print of the progress track sheet (similar to Figure 3: Sample Progress Track with Issue History) serves the same purpose. The team members report progress using colored markers, which they glue to the wallpaper. It requires more physical presence of the project office that has to input the data captured on the wallpaper into the Excel sheet but minimizes disruption for the develop- METRICS FOR PROJECT MANAGEMENT V10.DOC Copyright © 2003 Euro Project Office Page 13 of 15 UKSMA Conference Wolverhampton Metrics for Project Management Publication Dr. Thomas Fehlmann Version V1.0-13, 23 September, 2003 ers and maximizes their sense of responsiveness and ownership. This effect could be worth considering as a trade off. Figure 5: Wall Sized Print of the Progress Track as Paper Tool Automated Data Capture using a Project Repository If a project repository is available, data capture is even more automated. The draft deliverables, quality records and approvals can be tracked in the project repository and progress track relies less on people’s judgement. Team members still have to update time and issue reporting on the tickets and may want to set the draft or the review to some intermediary progress grade (yellow marker). However they can no longer pretend be in finalization state without at least a preliminary review report being available in the project repository1. Relation to Other Software Metrics Bad effort estimation cannot be completely avoided. Using the Six Steps To Completion method, errors in estimation are detected in the very early stages of the project. Delivery rates become apparent from the beginning. 1 For a project repository that integrates well see itp.montana (www.itp-solutions.ch, in German) METRICS FOR PROJECT MANAGEMENT V10.DOC Copyright © 2003 Euro Project Office Page 14 of 15 UKSMA Conference Wolverhampton Metrics for Project Management Publication Dr. Thomas Fehlmann Version V1.0-13, 23 September, 2003 When the team starts understanding that the progress metrics are not a threat but a valuable help for them, their reluctance against using metrics vanishes. The GMC team in Hradec Králové (Czech Republic) integrated the method in the open source tool Bugzilla. Thus tracking project tasks and bug fixes becomes the same process. Developers have only one tool that supplies them with new tasks, with their specifications, test cases, records test results and review finding, and tracks effort and progress. It provides progress metrics and bug statistics at once, with no pain. Clearly we would like to add a software sizing metric to the tool. However this yields some specific problems. The work breakdown structure of a software project does not automatically coincide with the software boundaries. Sometimes it is possible to group development tasks such that they fit with logical boundaries, but it make not always sense. Nevertheless, such an approach is very promising and deserves further investigation. Conclusion The Six Steps To Completion – metric is easy to use, simple and straightforward. In the beginning, it is often not even perceived as a metric, it stirs only little opposition, and almost no fear against being measured. On the other hand, the effects are tremendous. If planning and estimation was correct, the schedule will be respected. The metric establishes a short – circuit between plan and team. The project manager perceives unrealistic assumptions and estimations within a single reporting period. We most often use one week, sometimes two weeks as a reporting period. Thus corrective actions can be taken immediately when needed. Metrics provide huge benefits for people and organizations. Progress metrics are the door opener for other metrics dearly needed for today’s complex tasks. Moreover, many more sophisticated metrics such as software sizing using Function Points or bug statistics provide higher value when combined with progress metrics. This is why we us no metrics without progress metrics in our software projects. METRICS FOR PROJECT MANAGEMENT V10.DOC Copyright © 2003 Euro Project Office Page 15 of 15
