For this reason it is necessary to make an estimate considering who will actually do the work..<\/li>\n<li><strong>External pressure<\/strong>: Many project managers are assigned specific &#8211; and sometimes unrealistic &#8211; project effort and cost objectives. If a project manager finds himself in this situation, they should communicate what they think is within reasonable reach.<\/li>\n<li><strong>Failure to involve the executors of the activity: <\/strong>an estimate developed without involving the executors of that activity could be inaccurate because it is based on erroneous conceptions. This is why a direct comparison between the estimator and the executor is always important.<\/li>\n<\/ul>\n<p><a name=\"estimation\"><\/a><\/p>\n<h2>\u00a0Planning Game: an estimation method<\/h2>\n<p>In addition to the traditional methods to<strong> estimate the effort and costs<\/strong> of a project, another one exists, mainly used by the <a href=\"https:\/\/twproject.com\/blog\/manage-agile-team\/\" target=\"_blank\" rel=\"noopener\">Agile teams<\/a>: the <strong>Planning Game<\/strong>.<\/p>\n<p>The purpose of using this method is to avoid the<strong> influence of other participants<\/strong>.<\/p>\n<p>The<strong> Planning Game <\/strong>should force people to <strong>think independently <\/strong>and propose their estimate numbers at the same time,<strong> without input and influence<\/strong> from other participants.<\/p>\n<p>Let&#8217;s see how a <strong>planning game <\/strong>normally takes place. Each participant has a <strong>series of cards with an estimated value<\/strong> (the values can be those, even approximate, of the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Fibonacci_number\" target=\"_blank\" rel=\"noopener\">Fibonacci sequence<\/a>).<\/p>\n<p>The individual activities to be carried out will then be taken into account. Each team member considers all the factors of the project activity and selects a card that they will place face down on the table. Once all participants have made their move, the cards are turned.<\/p>\n<p>It is not possible to select two cards for the same activity.<\/p>\n<p>Then, the participants will review the assessments made and discuss together the reasons for their choices.<\/p>\n<p>Each participant, in this way, will think independently and how much effort the team will spend to complete the activity in question.<\/p>\n<p>Once the discussion is over, the evaluation will be repeated until all the participants give the activity the same value. Then, this value will be written on the Activity in question and the process will be repeated for the next Project Activity, and so on until the end.<\/p>\n<p>For each activity, the highest and lowest values attributed will be crucial. It is not necessarily the case that those who have given such assessments are wrong, but it may be possible that these team members may have valuable information or knowledge for a more realistic estimate.<\/p>\n<p>This way, at the end of the Planning Game, a shared estimate of each individual project activity will be made. In this way, no team member and no external stakeholders can blame anyone for incorrect estimates.<\/p>\n<p>The <strong>Planning Game<\/strong> is sometimes also called <strong>Planning Poker<\/strong> or<strong> Scrum Poker<\/strong>, and is a derivation of the <strong>Delphi Method<\/strong>, a group decision-making technique in which participants give their estimate to a facilitator who is responsible for providing an anonymous summary of the expert evaluations along with an explanation.<br \/>\n<a name=\"conclusions\"><\/a><\/p>\n<h2>The Planning Game to overcome the risks of estimating the effort: conclusions<\/h2>\n<p>Ultimately, <strong>the most adequate effort and cost estimation technique for each individual project <\/strong>depends on the experience of the project manager, their preference and the parameters available in each situation.<\/p>\n<p>In addition, there are now <strong>project management software<\/strong> programs that use statistics to help project managers calculate contingencies to deal with risks, uncertainties, and unknowns relatively smoothly.<\/p>\n<p>Although there are some minor differences, the basic concept is the same in all tools: to provide a set of possible results for the individual work elements of each project.
