Effort is person-hours. A task needing 16 hours of one person&#8217;s time takes four days if they&#8217;re only on it half-time.

They usually aren&#8217;t.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Resource levelling<\/strong> means adjusting the schedule so nobody is assigned more work than they can do. Two things to check:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Over-allocation.<\/strong> Look for one person assigned to overlapping tasks. In our project, C (wireframes) and D (visual design) both belong to the designer \u2014 but they&#8217;re sequential, so there&#8217;s no conflict. If E and G had both been the content lead&#8217;s work running in parallel, you&#8217;d have a problem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Availability.<\/strong> Holidays, part-time contracts, and people split across projects all change duration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The trade-off to know:<\/strong> levelling often pushes the end date out. That&#8217;s not a failure \u2014 it&#8217;s the schedule becoming honest about who&#8217;s actually available.<\/p>\n\n\n\n<h2 id=\"step-9-how-do-you-compress-a-schedule\" class=\"wp-block-heading\">Step 9: How Do You Compress a Schedule?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Say the client wants launch in 26 days instead of 28. Two techniques, and they cost different things.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Crashing \u2014 add resources to critical tasks<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Add people or hours to shorten a task. <strong>Only works on the critical path<\/strong>, and only pays if you pick the cheapest day saved.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Task<\/th><th>Current<\/th><th>Crashed<\/th><th>Days saved<\/th><th>Extra cost<\/th><th><strong>Cost per day<\/strong><\/th><\/tr><\/thead><tbody><tr><td>D \u2014 Visual design<\/td><td>6<\/td><td>4<\/td><td>2<\/td><td>\u00a31,200<\/td><td><strong>\u00a3600<\/strong><\/td><\/tr><tr><td>F \u2014 Build templates<\/td><td>7<\/td><td>5<\/td><td>2<\/td><td>\u00a32,000<\/td><td>\u00a31,000<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Crash D.<\/strong> Same two days saved for \u00a3800 less.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Now recalculate \u2014 this is the step people skip.<\/strong> With D at 4 days, the lower path becomes 26 days. The upper path is still 24. So the critical path holds, but float on B and E drops from 4 days to 2. <strong>Compression consumes your safety margin somewhere else<\/strong>, and if you crash far enough the critical path shifts to a different route entirely.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Fast-tracking \u2014 overlap tasks that were sequential<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Start F before D fully finishes \u2014 begin building templates from the approved wireframes while visual design completes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Costs nothing in money. Costs you rework risk.<\/strong> If the visual design changes after the build starts, some of that build is wasted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The honest rule:<\/strong> crash when you have budget, fast-track when you have tolerance for rework, and do neither on tasks with float \u2014 it buys you nothing.<\/p>\n\n\n\n<h2 id=\"step-10-what-is-a-schedule-baseline\" class=\"wp-block-heading\">Step 10: What Is a Schedule Baseline?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>A baseline is a saved copy of the approved schedule.<\/strong> Once set, you don&#8217;t edit it \u2014 you compare against it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Without a baseline, every schedule update quietly rewrites history and &#8220;we&#8217;re on track&#8221; becomes unfalsifiable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Baseline these three together:<\/strong> scope, schedule, and budget.

The tables in this article.<\/strong> The task list, dependency table, forward and backward pass, float table, and finished schedule are all copyable. Together they&#8217;re a complete working template, and the worked numbers show you what a filled-in version looks like.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2. Your own past projects.<\/strong> Usually the best source \u2014 the durations reflect how your team actually works rather than an average. If you&#8217;ve run a similar project, that schedule is your template.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>3. Your tool&#8217;s built-in templates.<\/strong> Microsoft Project, Smartsheet, Asana, and most others ship with templates by project type. Useful for structure; always wrong on durations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>4. Professional bodies and vendors.<\/strong> PMI publishes templates and insights for members. Major vendors publish scheduling templates for their platforms.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>One caution.<\/strong> Most free schedule templates online are empty <a href=\"https:\/\/www.gantt.com\/\" target=\"_blank\" rel=\"noopener\">Gantt charts<\/a> \u2014 a grid with no logic in it. A template without dependency relationships can&#8217;t calculate a critical path, which means it can&#8217;t tell you which delays matter. <strong>Check that the template has a predecessors column before you adopt it.<\/strong> If it doesn&#8217;t, it&#8217;s a picture of a schedule rather than a schedule.<\/p>\n\n\n\n<h2 id=\"which-books-and-standards-are-worth-knowing\" class=\"wp-block-heading\">Which Books and Standards Are Worth Knowing?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Two references most scheduling professionals encounter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>PMBOK Guide<\/strong> (Project Management Institute) covers schedule management as a knowledge area \u2014 defining activities, sequencing them, estimating durations, developing the schedule, and controlling it. It&#8217;s the framework most certifications test against.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Harold Kerzner&#8217;s <em>Project Management: A Systems Approach to Planning, Scheduling, and Controlling<\/em><\/strong> (Wiley) is the long-standing textbook in this field, now in its thirteenth edition. It goes considerably deeper than any article can, particularly on earned value and organisational context. If you&#8217;re moving from running projects to teaching or certifying, it&#8217;s the standard reference.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Standards get revised.<\/strong> Check which edition your organisation or certification body expects.<\/p>\n\n\n\n<h2 id=\"8-scheduling-mistakes-to-avoid\" class=\"wp-block-heading\">8 Scheduling Mistakes to Avoid<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>1. Opening the scheduling tool first.<\/strong> Scope, then WBS, then tasks, then dates. Never dates first.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2. Confusing duration with effort.<\/strong> Sixteen hours of work at half-time availability is four days, not two.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>3. Inventing dependencies.<\/strong> &#8220;We&#8217;d rather do it that way&#8221; is a preference. False dependencies make the schedule longer than the work requires.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>4.

Scheduling turns that into dates and sequence. You can&#8217;t schedule work you haven&#8217;t defined, which is why opening the scheduling tool first is the most common mistake.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1789643343257\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>What is the critical path?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The longest chain of dependent tasks through a project. It determines the shortest time the project can take. Tasks on it have zero float \u2014 any delay to them delays the whole project.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1789643344577\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>What is float in project scheduling?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>How long a task can slip without delaying the project. Calculate it as Late Start minus Early Start. Zero float means the task is critical. In the worked example above, copywriting has 4 days of float while visual design has none.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1789643345756\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>How do you calculate the critical path?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Run a forward pass to get earliest start and finish dates, then a backward pass for latest start and finish. Float is Late Start minus Early Start. Tasks with zero float form the critical path. Step 7 shows the full calculation with numbers.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1789643346810\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>What is a three-point estimate?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Three durations \u2014 optimistic, most likely, and pessimistic \u2014 combined with the PERT formula: (O + 4M + P) \u00f7 6. For 5, 8 and 17 days, that gives 9 days. It prices in risk that a single-point estimate hides.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1789643348496\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>What is the difference between crashing and fast-tracking?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Crashing adds resources to shorten critical tasks \u2014 it costs money. Fast-tracking overlaps tasks that were sequential \u2014 it costs rework risk. Both only help on the critical path, and after either you must recalculate, because the critical path can shift.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1789643449780\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>Why is scheduling important in project management?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>It shows the sequence you can&#8217;t change, tells you which delays actually matter, surfaces resource conflicts before they happen, and gives you a baseline to measure against. Without it, every delay looks equally urgent.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1789643451108\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>What are the benefits of project scheduling?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Earlier warning of slippage, better decisions about where to spend recovery effort, realistic commitments, fewer resource collisions, and defensible change control \u2014 &#8220;this change adds 6 days to the critical path&#8221; is a fact rather than an opinion.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1789643454478\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>What tools are best for project planning and scheduling?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Primavera P6 for large engineering and construction, Microsoft Project for mid-size predictive work, Smartsheet for teams wanting spreadsheet familiarity, Jira for agile delivery. Check whether your tool calculates float \u2014 many popular tools draw timelines without doing true critical path analysis.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1789643456080\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>Do agile projects need a schedule?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Yes, in a different form. Sprints are fixed timeboxes, release plans are forecasts, and velocity does the arithmetic the critical path does in a predictive plan. Most real projects run hybrid: predictive dates for external commitments, iterative delivery inside them.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1789643525453\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>What is a schedule baseline?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>A saved copy of the approved schedule that you compare progress against rather than edit. Baseline scope, schedule, and budget together, and only re-baseline through formal change control with a recorded reason.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1789643526627\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>How often should you update a project schedule?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Weekly, on a fixed day. A schedule updated whenever someone remembers is a schedule nobody trusts, and irregular updates make variance analysis meaningless.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\"><strong>Related reading:<\/strong> <a href=\"https:\/\/writegenic.ai\/content\/risk-assessment-plan-template\/\">Risk Assessment Plan Template<\/a> \u00b7 <a href=\"https:\/\/writegenic.ai\/content\/risk-response-strategies\/\">Risk Response Strategies<\/a> \u00b7 <a href=\"https:\/\/writegenic.ai\/content\/functional-design-specification\/\">Functional Design Specification<\/a> \u00b7 <a href=\"https:\/\/writegenic.ai\/content\/ai-generators\/ai-for-project-management\/\">AI for Project Management<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Project planning and scheduling explained in 10 steps, with one example project carried through \u2014 including a full critical path calculation you can check.<\/p>\n","protected":false},"author":4,"featured_media":32015,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[97],"tags":[32],"class_list":["post-31874","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-project-management-guide","tag-project-management"],"authors":[],"_links":{"self":[{"href":"https:\/\/writegenic.ai\/content\/wp-json\/wp\/v2\/posts\/31874","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/writegenic.ai\/content\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/writegenic.ai\/content\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/writegenic.ai\/content\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/writegenic.ai\/content\/wp-json\/wp\/v2\/comments?post=31874"}],"version-history":[{"count":1,"href":"https:\/\/writegenic.ai\/content\/wp-json\/wp\/v2\/posts\/31874\/revisions"}],"predecessor-version":[{"id":33648,"href":"https:\/\/writegenic.ai\/content\/wp-json\/wp\/v2\/posts\/31874\/revisions\/33648"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/writegenic.ai\/content\/wp-json\/wp\/v2\/media\/32015"}],"wp:attachment":[{"href":"https:\/\/writegenic.ai\/content\/wp-json\/wp\/v2\/media?parent=31874"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/writegenic.ai\/content\/wp-json\/wp\/v2\/categories?post=31874"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/writegenic.ai\/content\/wp-json\/wp\/v2\/tags?post=31874"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
