Comment estimer les coûts d’un projet avec des informations limitées ?

Uff that's a difficult one ... In the absence of comprehensive project information, defining the scope becomes a critical first step in estimating project costs. Begin by engaging with stakeholders to gather as much detail as possible about project objectives, deliverables, and constraints. While the information may be limited, collaboration with subject matter experts and stakeholders can provide valuable insights. Clearly delineate the project boundaries and break down the scope into manageable components. This process helps identify the key factors that may impact costs, laying the foundation for a more accurate estimation. We did this when we launched our first AI product and it was extremely helpful.

To estimate the project cost with limited information is a daunting task. Add to it if the stakeholders are of not much help, then it becomes that much more difficult. At this point, start at the deliverable or the end goal. With this information, understand the scope of the project. Engage industry experts, discuss and gather as much information as possible about constraints and costs for each work breakdown structure. On top of this, add the resource and operational costs. With few iterations, the project cost could be estimated, and this can be used as a baseline for future estimations.

Estimating project costs with limited information requires a systematic approach. Start with gathering info around historical projects, similar projects from teams, stakeholders, experts and market research data - Start with high-level estimate based on overall project characteristics, such as size, complexity, and industry benchmarks. Break down this estimate into smaller components and allocate costs to different elements. This acts as a starting point - Then apply a 3-point estimation approach, considering optimistic, pessimistic, and realistic scenarios. Calculate weighted average to arrive at a central estimate. - Do a sensitivity analysis to identify variables that have most significant impact on costs - Have contingency reserves

Scoping a project is tying features to consumer needs. Each pair is ja variable towards creating a scope of work that results in product market fit. That said, always start with the end user and work backwards. From a quantitative perspective, review consumer trends and see if there are pockets of under served consumers and ask whys. Additionally, understand how your competitors create value for the end user and explore how the scope of your project can differentiate from what is currently available or simply do it better but at lower cost. Lastly, and depends on the project, talk to people. You can create simple landing pages to gather more insight for a recommendation for design, pricing, positioning, and distribution.

Range Estimation: Method: Provide a range of estimates to account for uncertainty. For example, low, medium, and high estimates based on optimistic, most likely, and pessimistic scenarios.

Leveraging historical data is a key strategy for estimating project costs when faced with limited information. Analyze data from past projects that share similarities in terms of scope, scale, and complexity. Historical cost information, resource allocations, and timelines from these analogous projects serve as valuable benchmarks. By identifying patterns and trends, project managers can make informed assumptions and adjustments to account for differences in the current project. This historical perspective provides a basis for creating more realistic and grounded cost estimates, even when specific details are scarce.

Use market data and historical data - what data is available from public competitors, what are industry standards, what are market trends?

When dealing with limited project information, applying estimation techniques becomes essential for generating meaningful cost estimates. Techniques such as analogous estimating, parametric estimating, and three-point estimating offer structured approaches. Analogous estimating draws parallels with similar completed projects to estimate costs. Parametric estimating uses mathematical models based on key project parameters. Three-point estimating involves considering optimistic, pessimistic, and most likely scenarios to establish a range of potential costs. These techniques provide a systematic framework for making educated assumptions and extrapolating costs based on available information.

In my logistics project, I had to deliver giant items to doorsteps, a first for our town. No data meant cost estimates were a total guesstimate! But instead of panicking, I got creative with parametric estimating. This fancy term just means I looked for links between project features and costs. Think size, distance, and team size. Using these, I built a model that sniffed out potential cost bombs. Then, I added some extra funds for surprises, just in case. The result? We delivered that project on time and on budget! Parametric estimating and a little buffer saved the day.
