The Art of Realistic and Accurate Estimating

efficient estimating Realistic and Accurate Estimating in Business

 

As a small business owner, I struggle with quoting prices and scheduling. I end up overpromising to the customer, stressing out my people, and hurting the bottom line. I underestimate the work involved. That puts pressure on my employees to deliver within an unrealistic time frame. The cost to produce is higher than expected while I underprice the job. How do I stop this from happening? I need to get a handle on more accurate estimating.

Thoughts of the Day: Get a handle on the size, frequency, and type of cost overruns. Develop a process for accurate estimating that includes operations sign-offs. Whenever there’s a discrepancy between what the customer was promised and what really happened hold delta meetings. Document what went wrong. Recognize that owners can often be people pleasers. Customers can work that lever to their advantage.

Identify root causes that are causing estimating errors.

Accurate estimating is key. Look for the root causes of your problems.

  • Are there errors in estimating due to price changes, incorrect inputs, things being left out?
  • How about discrepancies between what was quoted and customer expectations for quality or quantity?
  • What happens when jobs are rushed?

Some commodities and vendor services can change rapidly in price. Publish a list of price-sensitive materials and subcontractors. Inform customers that these prices will be confirmed once the order is placed.

Get organized for each job and make sure to communicate throughout.

Make a detailed material list, work plan, and budget for each job. Review with operations before committing to the customer. For accurate estimating, ask employees to challenge you if there are cost overruns or delayed delivery. Notify the customer before proceeding. Negotiate a solution.

For accurate estimating, communicate with customers the following:

  • Put everything in writing.
  • Specify quality, quantity, and due dates.
  • Get operations in agreement before sending anything to customers.
  • Make sure customers review and approve everything in writing.

Have a process map from sale to production to delivery.

Make room for rush work, but keep enough flexibility for last-minute changes. Ask production to under-schedule, so they can insert rush requests without disturbing other orders. Negotiate schedule changes with production staff before making delivery commitments to clients. Create process maps for everything. Document materials, time, and workforce required to produce. Turn those into standard estimating forms, which can be used to create accurate estimates and realistic budgets.

As soon as the contract or PO is signed, purchase all price-sensitive items. If there are a lot of price-sensitive items, ask customers for upfront payment to hold prices. This way you can order materials immediately without dipping into cash flow.

Plus/Delta meetings can help debrief with the team.

Use “plus/delta” review meetings to discuss what happened with all jobs deemed “out of bounds”.

    • Note what went right (“plus”) and what went wrong (“delta”).
    • Carefully debrief jobs that are less profitable or take longer than promised.
    • Incorporate the delta notes into selling and production improvements to reduce or eliminate the chance they’ll occur again.

Figure out why & how accurate estimating mistakes happen, then adjust.

If you do run into problems while in production, ask employees to notify you immediately. Know who at the customer to contact and call immediately to work out specifics of what will happen next. Be honest and be prepared to negotiate a solution that will work for both you and the customer.

Sometimes production makes an error. They misunderstood what was expected, or didn’t follow instructions. Your company should deal with the problem, don’t push that back to the customer.

Balance building client relationships and protect your company and team.

Recognize that clients with last-minute requests may be very persuasive. Saying, “yes”, without being able to meet their demands will only serve to wreck the relationship when it comes time to deliver and you’re behind schedule or over budget. If the owner is a soft touch who gives away too much, but someone else in the middle between company and client. Pick a designated “tough guy” to hammer out contract details, prices, and delivery schedules.
