Everything takes longer and costs more? And <strong>planning security<\/strong> seems to be a foreign concept? Today we&#8217;ll show you that this doesn&#8217;t have to be the case. <br>The predictability of IT development projects can be significantly increased <strong>in just five steps<\/strong>. The BAMAC GROUP uses a tried and tested data analysis procedure to estimate expenses.<\/p>\n\n\n\n<h4 class=\"wp-block-heading has-bamac-dark-beige-color has-text-color\" id=\"h-initial-situation\">Initial situation<\/h4>\n\n\n\n<p>IT project portfolio management involves the <strong>planning<\/strong> and <strong>management<\/strong> of <strong>all IT projects<\/strong> within an organization. The basis of an IT project are the requirements that are to be implemented in the form of functions in the IT products. To do this, it is necessary to determine which <strong>requirements<\/strong> are to be met and how much <strong>effort<\/strong> and <strong>functionality<\/strong> the new IT products will require. We would like to emphasize one thing at this point:<\/p>\n\n\n\n<h4 class=\"wp-block-heading has-text-align-left has-bamac-gold-color has-text-color\" id=\"h-the-effort-and-functional-scope-of-it-projects-are-not-linear-and-are-therefore-not-intuitive\">The effort and functional scope of IT projects are not linear and are therefore <strong>not<\/strong> intuitive!<\/h4>\n\n\n\n<p>These <strong>exponential growth curves<\/strong> are caused by a number of external circumstances. The inherent <strong>agility<\/strong> of IT projects has a direct impact on planning capability. The degree to which information is passed on and the quality of information within the various teams, specialist departments, etc. also has an influence on the progress of the IT project. The same applies to the <strong>targets<\/strong>. Whether and how clearly these are formulated, whether they are fixed or rather roughly outlined, influences the process and the <strong>planning reliability<\/strong> of an IT project.  <\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-for-this-reason-a-high-estimation-quality-contributes-to-an-improved-predictability-of-it-development-projects\">For this reason, a high estimation quality contributes to an improved predictability of IT development projects.  <\/h4>\n\n\n\n<p>We will show you how this can be achieved. <\/p>\n\n\n\n<h4 class=\"wp-block-heading has-bamac-dark-beige-color has-text-color\" id=\"h-how-do-you-estimate\">How do you estimate?<\/h4>\n\n\n\n<p>In the following, we will show you how to obtain an estimate. First, data on your own <strong>productivity<\/strong> is stored in the baseline. The productivity data was determined by recalculating completed projects. This process increases the estimation quality.<\/p>\n\n\n\n<p>In this <strong>case study<\/strong>, a rough concept with the functional and technical requirements was available. For this reason, an estimate was initially carried out as part of the quotation process. This was then incorporated into the IT project portfolio planning. The aim was to achieve a <strong>high estimation quality<\/strong> and to point out any risks at the estimation stage.  <\/p>\n\n\n\n<h4 class=\"wp-block-heading has-text-align-left has-bamac-gold-color has-text-color\" id=\"h-an-estimate-must-be-accurate-and-repeatable\">An estimate must be accurate and repeatable.<\/h4>\n\n\n\n<p>There are <strong>two<\/strong> important <strong>criteria<\/strong> to consider when making an estimate. <strong>It must be accurate and repeatable<\/strong>, as this ensures that IT development projects can be better planned. <br>In order to ensure the aspect of repeatability, we proceed in <strong>two steps<\/strong> when calculating expenses. First, we use function point analysis to determine the <strong>scope of functions<\/strong> according to the functions to be implemented. We measure this scope in Function Points (FPs). Based on the FPs, we use the above-mentioned company-specific baseline to determine the required <strong>effort in person days<\/strong> (PT). If such a database is not available, we use data from the BAMAC GROUP. From experience, we can say that if a company-specific baseline is used for the estimate, the quality of the expense is less than 5%.  <\/p>\n\n\n\n<h4 class=\"wp-block-heading has-bamac-dark-beige-color has-text-color\" id=\"h-when-is-the-estimate-made\">When is the estimate made?<\/h4>\n\n\n\n<p>An estimate is always made when the scope of functions changes. <strong>Changes in the scope of functions<\/strong> can occur consciously during the course of the project due to further detailing or extensions to functions, or unconsciously. This process of unconscious expansion is also known as scope creep. A score creep is caused, for example, by detailing functions that are already known. Estimates are therefore <strong>made more frequently<\/strong><strong> during <\/strong>the implementation of the IT project. <br>Typical times are  <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Preliminary project  <\/li>\n\n\n\n<li>Project order<\/li>\n\n\n\n<li>Analysis &amp; Design<\/li>\n\n\n\n<li>Implementation  <\/li>\n\n\n\n<li>Test  <\/li>\n<\/ul>\n\n\n\n<p>In other words:  <br>the <strong>effort required to implement<\/strong> the project is the subject of the estimate. <strong>The more precisely<\/strong> the <strong>effort<\/strong> is determined, the <strong>greater<\/strong> the <strong>predictability<\/strong> of IT development projects.<\/p>\n\n\n\n<h4 class=\"wp-block-heading has-bamac-dark-beige-color has-text-color\" id=\"h-the-estimation-process\">The estimation process  <\/h4>\n\n\n\n<p>The process for determining expenses is carried out in <strong>five steps<\/strong>.  <\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>First, the procedure, the data analysis and the timetable are presented in a <strong>kick-off <\/strong>meeting and any correlations are explained.  <\/li>\n\n\n\n<li>In the second step, the data provided by the company is <strong>analyzed<\/strong> with the help of function points. Documents containing the functional and technical requirements are used for the function point analysis. This includes a rough concept, technical concept, IT concept, test concept, change requests and user manuals.  <\/li>\n\n\n\n<li>The third step is a <strong>quality assurance<\/strong> <strong>workshop<\/strong>. In this meeting, the results of the data analysis are presented, anomalies are discussed and any unresolved issues are clarified. Subsequent improvements are also agreed here if they are necessary.  <\/li>\n\n\n\n<li>The fourth step is to <strong>follow up<\/strong> the workshop. In the course of this, the incorrectly identified assumptions from the QA workshop are corrected.  <\/li>\n\n\n\n<li>The <strong>final presentation<\/strong>, including a discussion of the results and optimization approaches, forms the fifth and final step in determining the costs.<\/li>\n<\/ol>\n\n\n\n<p><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"3170\" height=\"1690\" src=\"https:\/\/www.bamacgroup.com\/wp-content\/uploads\/ITPPM_Grafik-8e.jpg\" alt=\"\" class=\"wp-image-3411\" srcset=\"https:\/\/www.bamacgroup.com\/wp-content\/uploads\/ITPPM_Grafik-8e.jpg 3170w, https:\/\/www.bamacgroup.com\/wp-content\/uploads\/ITPPM_Grafik-8e-300x160.jpg 300w, https:\/\/www.bamacgroup.com\/wp-content\/uploads\/ITPPM_Grafik-8e-1024x546.jpg 1024w\" sizes=\"auto, (max-width: 3170px) 100vw, 3170px\" \/><figcaption class=\"wp-element-caption\"><strong>Figure 1: Process for determining the cost of development projects<\/strong> <\/figcaption><\/figure>\n\n\n\n<p>The <strong>time required<\/strong> by the stakeholders in the process described above can be very <strong>low<\/strong> if the requirements for the project to be realized are documented. If this requirement is not met, the functional analysis is carried out in workshops with the help of requirements managers and specialists.  <\/p>\n\n\n\n<h4 class=\"wp-block-heading has-bamac-dark-beige-color has-text-color\" id=\"h-results-of-the-estimate\">Results of the estimate<\/h4>\n\n\n\n<p>We explain our approach in more detail using the following <strong>example<\/strong>.  <\/p>\n\n\n\n<p>A rough concept is available as a basis at the time the offer is prepared. As described, we use the <strong>function point analysis<\/strong> as an estimation tool. In this example, the analysis result was 150 FPs. This result is confirmed in the quality assurance workshop. Using the baseline, we determine a development cost of 200 PT.

It therefore makes sense to <strong>repeat<\/strong> the <strong>estimate<\/strong> presented at different points in time.  <\/p>\n\n\n\n<p>Our findings can now be immediately incorporated into further planning. We also recommend including both milestone and capacity planning in the overall planning.  <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Are you looking for more planning security in the development of IT projects?
