Its value can be expressed in hours, weeks, months, or years \u2014 depending on the project&#8217;s complexity and length.&nbsp;<\/p>\n\n\n\n<p>Project managers typically assess ETC at the beginning of project planning to determine what resources they need and how to schedule their tasks and employees. Accurate ETC can help with creating budgets and resource allocation.<\/p>\n\n\n\n<p>Another process to consider is <em>Estimate Activity Durations<\/em>, which the <a href=\"https:\/\/www.goodreads.com\/book\/show\/34448751-a-guide-to-the-project-management-body-of-knowledge-pmbok-guide-sixth?from_search=true&amp;from_srp=true&amp;qid=aLXrZsjbNc&amp;rank=1\" target=\"_blank\" rel=\"noreferrer noopener\">PMBOK guide<\/a> defines as: \u201dThe process of approximating the number of work periods needed to complete individual activities with estimated resources.\u201d<\/p>\n\n\n\n<p>In other words, Estimate Activity Durations is a term that represents the time required to complete a single task that is part of a larger project. This process is performed throughout the project life cycle.<\/p>\n\n\n\n<h3 id=\"why-should-you-estimate-time-in-project-management\" class=\"wp-block-heading\">Why should you estimate time in project management?<\/h3>\n\n\n\n<p>Precise time estimations are essential for successful project completion, and you can use various methods and tools to improve these estimations.<\/p>\n\n\n\n<p>Other benefits of investing time, energy, and resources in making time estimations in project management include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Determining the number of employees, funding, and resources needed to complete the project,<\/li>\n\n\n\n<li><a href=\"https:\/\/clockify.me\/project-scheduling-software\" target=\"_blank\" rel=\"noreferrer noopener\">Scheduling<\/a> team members, tasks, and activities,<\/li>\n\n\n\n<li>Setting realistic and manageable deadlines,<\/li>\n\n\n\n<li>Ensuring that employees have enough time to complete their tasks,&nbsp;<\/li>\n\n\n\n<li>Delivering the project on time, and consequently<\/li>\n\n\n\n<li>Ensuring employer\u2019s or client\u2019s satisfaction.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>As we have previously mentioned, making an accurate ETC is not always easy, and errors occur for a number of reasons.

They will be pressured to complete more work than they can handle, which can result in stress, anxiety, and burnout.&nbsp;<\/p>\n\n\n\n<p>All this shows just how much setting precise time estimates is crucial in cultivating a successful business and creating a good company\u2019s reputation.&nbsp;&nbsp;<\/p>\n\n\n\n<p>To avoid making poor time estimates and their consequences, you should get familiar with one of productivity\u2019s cousins \u2014 microproductivity.

This activity is known as <a href=\"http:\/\/teevan.org\/publications\/papers\/chi16-microproductivity.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">microproductivity<\/a> and it consists of the following processes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Identifying the main task,<\/li>\n\n\n\n<li>Fragmenting said task into subtasks,<\/li>\n\n\n\n<li>Listing all the subtasks,<\/li>\n\n\n\n<li>Estimating the time required to complete each subtask, and&nbsp;<\/li>\n\n\n\n<li>Estimating the time you might allocate to breaks between subtasks.<\/li>\n<\/ul>\n\n\n\n<p>This is how microproductivity looks like in practice.&nbsp;<\/p>\n\n\n\n<p>For example, to \u201cwrite a blog post\u201d simply can\u2019t be a single task, as it actually consists of several different tasks \u2014 such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Conducting research,<\/li>\n\n\n\n<li>Looking for relevant references,<\/li>\n\n\n\n<li>Looking for relevant keywords,<\/li>\n\n\n\n<li>Writing an organized outline,<\/li>\n\n\n\n<li>Writing the actual content,<\/li>\n\n\n\n<li>Proofreading, spelling and grammar check,<\/li>\n\n\n\n<li>Writing effective headlines,&nbsp;<\/li>\n\n\n\n<li>Writing meta descriptions,&nbsp;<\/li>\n\n\n\n<li>Creating visuals, and<\/li>\n\n\n\n<li>Uploading posts to WordPress.<\/li>\n<\/ul>\n\n\n\n<p>In the example above, microproductivity refers to breaking one main task into 10 smaller assignments and allocating a separate time slot to each.&nbsp;<\/p>\n\n\n\n<p>The psychological effect of this approach will:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Help us be more goal-oriented,<\/li>\n\n\n\n<li>Boost our positive self-image,<\/li>\n\n\n\n<li>Lead to less procrastination, and&nbsp;<\/li>\n\n\n\n<li>Help us make better time estimates.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>Speaking of which, in the following section, we\u2019ll focus on some practical tips for making precise time estimates.<\/p>\n\n\n\n\n<div class=\"banner banner-dark clockify-gradient-landing-3\">\n    <div class=\"banner-text lg:pr-[6rem]\">\n        <span class=\"h4 text-lg translation-block mb-0\">Free time tracker<\/span>\n        <p class=\"translation-block mt-1 mb-3\">Time tracking software used by millions.

rel=\"noreferrer noopener\">break the project down into smaller tasks<\/a>.&nbsp;<\/p>\n\n\n\n<p>According to the PMBOK guide, \u201cdefining activities is the process of identifying the specific actions to be performed to produce the project.\u201d<\/p>\n\n\n\n<p>So, before making time estimates, make sure you define a list of tasks you need to complete during a time period.<\/p>\n\n\n\n<p>The best practice is to make a straightforward <a href=\"https:\/\/clockify.me\/blog\/managing-time\/to-do-list-methods\/\" target=\"_blank\" rel=\"noreferrer noopener\">to-do
