How to Improve Sales Performance Across Skills, Deals, and Forecasts
A system-level approach to improving how sales teams execute, qualify deals, and forecast revenue.
Sales leaders continue to invest in training, tools, and process changes to improve sales performance, yet results often remain inconsistent. Reps attend programs, new initiatives are rolled out, and reporting becomes more detailed, but win rates, deal quality, and forecast accuracy do not improve in a predictable way.
This inconsistency creates uncertainty around where performance is breaking down. Leaders can see the outcomes—missed forecasts, stalled deals, extended sales cycles—but they lack a clear view into how execution is unfolding inside live opportunities. Skill development, deal management, and forecasting are reviewed separately, which makes it difficult to understand how one influences the other.
This eBook examines sales performance through the lens of execution. It introduces a three-layer model that connects skill development, opportunity management, and forecasting into a single system. By examining how these layers interact, the guide shows why performance improvement stalls when execution is managed in isolation and outlines the conditions required for sustained improvement.

Who This Is For
It’s intended for:
- Chief Revenue Officers responsible for revenue performance, forecast accuracy, and executive-level visibility
- VPs of Sales accountable for how sellers execute inside opportunities and how deals progress through the pipeline

FAQ
How do you improve sales performance?
Improving sales performance starts with understanding how execution works across skills, opportunities, and forecasting. Performance improves when trained behaviors show up consistently in opportunities, when deal quality is inspected using clear criteria, and when forecasts are built on buyer-backed information.
Why doesn’t sales training always improve sales performance?
Sales training doesn’t always improve sales performance because many times skills are taught without changing how deals are managed afterward. The training happens, but the sales system stays the same.
When managers don’t inspect the specific behaviors taught, when opportunities aren’t evaluated using the same standards, and when forecasting doesn’t rely on the buyer information those skills are meant to uncover, sellers fall back into old habits. Training improves performance when reinforcement, inspection, and measurement are built into opportunity management and forecasting, and when the revenue team operates against the same execution requirements.
What metrics matter most when evaluating sales performance?
The most commonly affected metrics include win rates, average deal size, sales cycle length, quota attainment, and forecast accuracy.
How does deal quality affect sales performance?
Deal quality determines which opportunities enter the pipeline, receive effort, and influence forecasts. When opportunities are created without specific information from the buyer about their problems, impact, urgency, and decision process, teams spend time on deals that are unlikely to close. That lowers win rates, extends sales cycles, and weakens forecasts.
Deal quality improves when opportunities are only advanced after sellers capture clear buyer-confirmed information about why a change is needed, what it affects, and what happens if nothing changes. When those standards are enforced early, teams focus on opportunities that can move forward and performance metrics reflect execution quality rather than pipeline volume.
What role do managers play in improving sales performance?
Managers influence sales performance by controlling how opportunities are reviewed and advanced. They decide whether deals meet the required standards and whether sellers are applying the behaviors taught in training.
When managers review opportunities using consistent criteria and require specific buyer-confirmed information before deals progress, execution improves. When that inspection is absent, deal quality varies, trained behaviors fade, and performance depends on individual judgment rather than a shared execution standard.
Why are sales forecasts often inaccurate?
Sales forecasts are inaccurate because deals are forecasted before execution has been validated. Opportunities are committed without confirming whether the buyer has defined a problem, agreed on impact, or aligned internally on a decision.
Forecasting becomes unreliable when it operates independently from opportunity management. When the forecast is built on pipeline movement instead of inspected deal criteria, it reflects assumptions rather than evidence. Accuracy improves only when forecast inclusion is conditional on the same standards used to qualify and manage opportunities.
How do you know if sales performance issues are systemic?
Sales performance issues are systemic when results do not change after individual fixes are applied. When replacing people, running new training, or adding tools fails to alter outcomes, the problem sits in the system governing execution.
If performance remains consistent despite different sellers, managers, or initiatives, the issue is structural rather than individual.
About A Sales Growth Company
A Sales Growth Company helps revenue teams improve sales performance by fixing how execution is managed.
Our work is based on the Gap Selling methodology and focuses on defining execution standards across skills, opportunities, and forecasting. We work with teams to establish what information sellers must capture, how deals are evaluated, and how forecasts are built from inspected execution rather than assumption.
This guide reflects recurring execution breakdowns observed across sales organizations and the structures required to correct them.
