Illustrative engagements
How Hennessey support can work in practice.
Representative scenarios showing the type of challenge, intervention and value an engagement may address.
Business advisory & turnaround
Restoring control in an underperforming manufacturer
The situation
A privately owned manufacturer had grown quickly, but margin, delivery performance and management visibility had deteriorated. Customer complaints were increasing and the owners lacked a reliable view of priorities.
Hennessey's approach
A focused review connected financial performance, customer commitments, production flow, leadership accountabilities and operating controls. Immediate actions were converted into a 13-week recovery plan with a clearer management rhythm.
Outcome
Within the illustrative recovery period, production output increased by 18%, on-time delivery improved from 72% to 91%, customer complaints reduced by 27% and gross margin improved by 6 percentage points.
Services: Business diagnostic, turnaround planning, operational improvement and performance governance.
Financial & commercial
Improving margin visibility in a growing services business
The situation
A services company was winning more work but generating less cash than expected. Pricing varied, project costs were poorly understood and reporting focused on turnover rather than contribution.
Hennessey's approach
Pricing, utilisation, project cost, invoicing and cash collection were reviewed. A practical dashboard and project-level profitability measures were introduced alongside clearer quotation controls.
Outcome
Illustrative results included a 24% increase in operating profit, a 7-percentage-point improvement in contribution margin and a 19-day reduction in debtor days, strengthening both profitability and cash visibility.
Services: Profitability analysis, pricing, working-capital discipline and management information.
Change & transformation
Turning a stalled transformation into an executable programme
The situation
A multi-site organisation had launched several improvement initiatives, but priorities competed for resources and senior leaders received inconsistent status information.
Hennessey's approach
The programme was reset around fewer measurable outcomes, with clear workstreams, governance, milestones, risks, decisions and benefit owners. Managers received practical implementation and communication support.
Outcome
Milestones delivered on schedule increased from 46% to 88%, duplicated project activity reduced by 30% and the programme realised 15% more planned benefit within the first year.
Services: Programme mobilisation, change governance, stakeholder engagement and benefits realisation.
Leadership & coaching
Strengthening a management team during rapid growth
The situation
The founder remained the main decision point for almost every significant issue. Managers were technically capable but lacked confidence, shared accountability and clarity about their authority.
Hennessey's approach
Leadership workshops and individual coaching were combined with practical changes to decision rights and meeting disciplines, using live business challenges throughout.
Outcome
Routine decisions escalated to the founder reduced by 40%, management decision time improved by 32% and the founder released around one additional day each week for strategy, growth and key relationships.
Services: Executive coaching, management development, team effectiveness and delegated authority.
These are representative scenarios rather than named client engagements. The figures illustrate the type and scale of measurable improvement that an engagement may target; they are not guarantees. Actual outcomes depend on the organisation's starting position, evidence, leadership commitment and agreed scope.
