Timeframe Estimation Techniques

⏰ How To Improve Your Time Estimates (https://lnkd.in/egWd45RF), an honest article of lessons learned from going massively over on a fixed-price contract — with action points on what our estimates typically miss, how to estimate better and how to be prepared when things go sideways. By Dave Stewart. ✅ “Planned work” may be as little as 20% of the total project effort. ✅ “Extra work” increases proportionally to the complexity of the work. ✅ Account for changes (20%) and unexpected slowdowns (15%). ✅ Access to data, docs, tools, people is a huge estimate trap. ✅ Run postmortems on past projects to anchor yourself to reality. ✅ Estimate with at most 6–6.5 productive hours per day. ✅ Always estimate in ranges, and never in precise numbers. ✅ Safe way to estimate better is to estimate smaller units of work. ✅ Always add at least 15–20% of buffer time: you will need them. ✅ Every new team member speeds up the work by 1.5–1.8×. 🚫 Troubles start when designers aren’t involved in estimates. 🚫 Stakeholders rarely know what causes delays and extra costs. ✅ Re-iterate that late changes are expensive and cause delays. ✅ Life is full of surprises: budget too much, not too little. ✅ When in trouble, raise a hand, rather than doubling down. As Dave has rightfully noted, much of the work we do is actually happening “around the work” — on the fringes of the project, before, between and beyond actual design work. It covers everything, from daily routine tasks (emails, meetings, reports) to complex dependencies, unknowns and legacy limitations. In the past, I was always trying to underpromise and overdeliver. I was thinking that ultimately that would put me in a good light — appearing as accountable, reliable and committed to quality work, despite the initial scope. Yet it has also resulted in poor estimates, delays, late night work and overlapping projects. So instead, I started dedicating time into drafting a very detailed scope of work to estimate better. Typically it includes: 1. That’s how we understood the problem, 2. That’s what we believe the solution requires, 3. That’s the breakdown of tasks we’ll do, 4. That’s the assumptions we make, 5. That’s dependencies we uncovered, 6. That’s data, docs, tools, people need to be involved, 7. That’s how we are planning to solve it, 8. That’s when stakeholder’s (timely) input will be needed, 9. That’s milestones and timelines we commit to, 10. That’s the fixed scope of our final delivery, 11. That’s the delivery date we commit to, 12. That’s how pricing and payment will work, 13 That’s how we’ll deal with late adjustments and scope changes. And most importantly: for every step of the process — in emails, calls, meetings — make sure to mention that late scope changes are very expensive and will eventually cause delays. So ask for the best channels and frequency for communication with stakeholders. Chances are high that you will need it. #ux #design

How do we calculate the Duration of Activities at Construction Projects ?? (Refreshing basic knowledge for those concerned) Building a construction project is like traversing a complex map – accurate timing is crucial at every step. Knowing how long each activity takes keeps your project on track, budget in hand, and avoids frustrating delays. But how do you predict these durations? Here's a toolbox of powerful methods. 1. Expert Judgment: Tap the wisdom of experience! Seasoned professionals familiar with similar projects or specific tasks can offer invaluable insights. This method is quick and flexible, but individual biases or limited knowledge can affect accuracy. 2. Analogous Estimating: Learn from history! Analyze completed projects with similar tasks and adjust for differences in size or complexity. It's fast and efficient, but relies on finding truly comparable projects. 3. Parametric Estimating: Embrace the equation! This method uses established formulas based on specific activity elements, like square footage for painting or cubic meters for excavation. It's highly accurate for standardized tasks but less flexible for unique elements. 4. Three-Point Estimating: Embrace uncertainty! This method uses three estimates – optimistic, most likely, and pessimistic – for each activity, accounting for potential risks and variations. It offers a realistic range of possibilities, but requires careful estimation expertise. 5. Bottom-Up Estimating: Break it down! This method dissects complex activities into smaller, well-defined tasks. Each task gets its own duration estimate, then they're combined to form the whole activity's duration. It's detailed and meticulous, but can be time-consuming for intricate tasks. 6. Quantity-Based Estimating: Measure it out! This method links activity duration directly to the amount of work involved, like man-hours per unit of concrete poured. It's straightforward and efficient, but may overlook complex logistical factors or require detailed unit rates. 7. By Simulation (PERT): Embrace the random! Monte Carlo analysis, a form of PERT, introduces statistical randomness to activity durations. It runs numerous project scenarios, generating a range of possible completion times and their probabilities. It's powerful for complex projects with significant uncertainties, but requires specialized software and expertise. Remember, the ideal method depends on your project's needs. Consider factors like complexity, data availability, budget constraints, and desired level of accuracy. Mix and match, adapt, or use expert advice – find the perfect blend for your construction masterpiece.

In Agile, we don’t estimate to predict the future perfectly—we estimate to create shared understanding, reduce uncertainty, and enable smarter planning. As a Scrum Master, I often coach teams on estimation techniques not just to assign numbers, but to facilitate conversation and build team alignment. 🔍 Here are 5 estimation techniques I encourage teams to try, depending on context: 🔢 1. Planning Poker (Fibonacci Series-Based) Each team member uses cards based on the Fibonacci sequence (0, 1, 2, 3, 5, 8, 13, 21...) to estimate story points. ✅ Why Fibonacci? Because effort doesn’t scale linearly. As complexity grows, so does uncertainty—Fibonacci naturally accounts for that. 🔥 Outcome: Rich discussions, exposed assumptions, better clarity. 👕 2. T-Shirt Sizing Items are sized as XS, S, M, L, XL. ✅ Perfect for high-level planning or when story details are limited. 🎯 Useful in roadmap estimation or MVP scope discussions. 🪣 3. Bucket System Items are sorted quickly into predefined “buckets” (e.g., 1, 2, 3, 5, 8, etc.) collaboratively. ✅ Great for estimating a large backlog fast. 🤝 4. Affinity Estimation Team members organise stories in relative order of complexity, then assign story points. ✅ Promotes collaboration without over-analysis. 🎯 5. Dot Voting (Not for sizing) Helps prioritise which stories to estimate first when time is limited or the backlog is large. 💬 As a Scrum Master, I recommend ✔ Use Fibonacci for structured complexity scaling ✔ Don’t aim for perfection—focus on alignment & learning ✔ Switch techniques based on team maturity & backlog health ✔ Keep it fun, focused, and inclusive!

Estimating Project Timelines as a Product Manager: Art or Science? One of the trickiest parts of being a Product Manager is answering that question: "When will this be done?" Sound familiar? If you’ve been in the room when stakeholders eagerly await your timeline, you know the pressure of getting it right. But estimating timelines isn’t just about guessing or over-promising—it’s about balancing precision, collaboration, and transparency. After 5+ years of leading cross-functional teams in financial services, e-commerce, and tech, here are the 5 proven methods I’ve relied on to confidently estimate timelines—and get buy-in: 1️⃣ Break It Down with User Stories: Big tasks are scary; small tasks are manageable. Work with your team to break down epics into bite-sized user stories. Use techniques like planning poker to encourage discussion and uncover hidden complexities. 2️⃣ Leverage Historical Data: Past projects are a goldmine! Analyze velocity, cycle times, and bottlenecks from previous sprints. If a similar feature took 3 sprints before, that’s your baseline. 3️⃣ Collaborate on Assumptions: Estimations shouldn’t happen in isolation. Include engineers, designers, and stakeholders early. The more perspectives, the more accurate your estimate. 4️⃣ Account for the Unknowns: Spoiler: Things WILL go wrong. Build in buffers for unexpected challenges like scope creep, bugs, or external dependencies. A 10-20% buffer can save your sanity. 5️⃣ Communicate Constantly: No estimate is perfect. Keep stakeholders updated on progress, roadblocks, and changes. It’s better to over-communicate than to let surprises derail expectations. 💡 Engage with me!

Whether you're estimating time, cost, or resources, the method you use can make a significant difference. A simple and effective estimation technique that I often rely on is the 3-point estimation technique. This method is used to estimate the duration or cost of a project task by considering three different estimates: Optimistic Estimate (O): Ideal scenario Pessimistic Estimate (P): Worst-case scenario Most Likely Estimate (M): Realistic scenario These three estimates are then used to calculate a weighted average, providing a more realistic and balanced estimate: Expected Estimate = (O+4M+P)/6 Why Use 3-Point Estimation? 1. It provides a more accurate estimate compared to single-point estimates, which can often be overly optimistic or pessimistic. 2. By accounting for the best-case and worst-case scenarios, project managers can better prepare for uncertainties. 3. It enables project managers to plan more realistically by incorporating potential variability into the estimates, leading to more achievable project timelines and budgets. Suppose a team is tasked with developing a new feature for a product. After discussion, the team comes up with the following estimates: Optimistic (O): 3 days Most Likely (M): 5 days Pessimistic (P): 9 days Using the 3-point estimation formula: E = (3+4(5)+9)/6 The expected duration for the task is approximately 5.33 days. This technique is particularly useful in projects with a high degree of uncertainty or where historical data is limited. Give it a try! Found this insightful?
