An analogy is a set of comparisons you draw between two things with similar characteristics. Analogous estimating is also known as "top-down" estimating because you apply the total costs from a previous project in order to estimate the total costs of a new one. Just keep breaking the budget down according to the new work breakdown structure (WBS).
The main benefit of using the analogous estimating technique is that it is less costly than other estimating techniques. The down side of using this technique is that it is also generally less accurate.
You may be wondering, "If analogous estimating is not considered to be accurate, why would I use this technique?" However, before you disregard analogous estimating altogether, you should be aware of the circumstances under which it is most reliable. It is particularly beneficial when the following conditions are present.
1. The new and previous projects are similar
There are two situations in which analogous estimating is used. One is when your project is similar to other, previous projects. The more similar the projects are, the more accurate the estimates will be. You also can base estimates on a similar project when you don't have detailed information about a new project. More details are provided below.
- Are they similar? To determine the degree of similarity between the past and current projects, examine the scope and purpose of the former project to ensure the projects are alike in fact, and not just in appearance.
- Not enough detail. Sometimes important costing information becomes available only after a project has begun. A similar project's budget will provide a general baseline to go by.
Knowledge about, and experience with, the subject matter determines whether the individuals preparing the estimates have the needed expertise. You may want to hire one or more external experts to help with cost estimating.
3. The estimating team has access to adequate information about the previous project
If your current project lends itself to the analogous estimating technique, you'll want to furnish your cost estimating team with everything they will need to produce accurate results. Listed below are some types of information they should have on hand when they are developing cost estimates using analogous estimating.
- Scope statements. The team will not know whether two projects are in fact similar unless it can compare descriptions of the project and product scopes.
- Work breakdown structure. The work breakdown structure from the previous project is also necessary to ensure that similar processes and steps will be followed in the current project. Differences in the two projects could affect the accuracy of cost estimates.
- Performance reports. Actual costs are the most important information from the old project. Your team will use them to determine which of the previous estimates were accurate. It should use the actual costs to revise any inaccurate estimates before copying them into the new project.

1. Plan your day using time management techniques
As a project manager, time management skills are essential because you are dealing with a wide range of tasks that demand a quick turnaround time. Planning your day will go a long way in keeping you organized and increasing your productivity. Assist your task planning by using project management software which helps you track the work of you and your team.
If you are not very tech savvy, a simple to-do list can also be a great organizational tool. Prioritize your most important tasks by putting them at the top of the list and less important ones at the bottom. Having a visual plan of your daily tasks helps to keep you on track and aware of time.

2. Include stakeholders in important project conversations
While you will have plenty of responsibilities regarding the project, don’t neglect your clients.
Good communication is essential is keeping both parties informed of project progression, curtailing scope creep, and apprised of changing requirements. Some clients may have different expectations when it comes to communication, so make sure to establish the frequency and type of communication (like emails, phone calls, and face-to-face conversations) at the beginning of your project.
Establishing communication expectations early helps alleviate stakeholder uncertainty about communication frequency and delivery.
3. Regularly communicate with your team
Daily team communication helps keep misunderstandings and unclear requirements under control. Keeping your team informed in every step of the project is essential to project management success.
For example, a study published by Procedia Technology found that good communication skills were the cornerstone of project management. The study examined over 300 “construction project managers, architects, construction managers, engineers and quantity surveyors” and their successes and failures on various construction projects.
4. Anticipate project setbacks
Even the best-laid plans often go awry.
Remember that even with a high amount of planning and attention to detail, your project may still encounter some challenges. Pay attention to complaints from stakeholders or colleagues, and other warning signs, like a missed deadline or cost overrun, that there may be a problem.
Preventing a crisis will keep your project running smoothly, save you a lot of time, and keep you, your team, and your stakeholders confident in progressing with the project.
Unfortunately not every complication can be avoided. Crisis management skills are essential for dealing with the unexpected. Project managers need to be flexible and pragmatic. Improvise and make sharp decisions when needed.

A common problem project managers encounter is having the project aims not aligned with the organization’s objectives. A great project manager will strategize a plan for the project to lead back to the overall success of the business.
Know your project’s scope by heart and avoid wandering outside of the project’s requirements. It’s too easy to get lost in minor details and forget what your focus is, so a well-planned project scope is essential for success.
