A performance or conduct problem is not always fixed by working on one person.
Before we suggest anything, we find where the problem actually sits:
SELF (Individual)
One leader's judgement and behaviour under pressure, like the call made late in the day with half the facts.
WE (Relational)
How your senior leadership team challenges, decides, and works together.
SYSTEM (Structural)
The rules, workloads, reporting lines and physical setting that limit what people can reasonably do.
Fix what is actually in the way. Don't ask one leader to make up for a broken system.

Backed by Science, Delivered by Experience.
Leadership relationship quality is associated with people actually leaving, not merely intending to.

LimitsAssociation, not cause. North American samples.
Challenge sits here because it is what the four days actually do. No meta-analysis links it to attrition, so it is marked as practice rather than evidence.
Working conditions predict future sick leave, measured over time rather than at a single moment.

LimitsJob conditions, not leader behaviour. Prospective, not experimental.
Lost productivity is not listed here. We could not find a meta-analysis linking these levers to a presenteeism outcome, so we do not claim one.
Safety climate is associated with the incident count itself, across the largest study of its kind.

LimitsIndustrial workforces. The read across to psychosocial risk is by analogy.
Where followers see their leader as ethical, self-reported deviance is lower.

LimitsPerceptions of ethical leadership, not audited conduct.
Role ambiguity degrades performance. Role conflict, which is often treated as the same thing, does not.

LimitsGeneral job performance.
This row rests on the least direct evidence of the eight. Structured discussion is known to improve what a group knows (Mesmer-Magnus and DeChurch, 2009, across 72 studies and 4,795 teams), and the operational indicator is agreed with you rather than assumed.
Trust inside a team predicts team performance, and it holds even after controlling for how the team performed before.

Business units in the top quartile of engagement differ from those in the bottom quartile on every operational measure the business already tracks.

How a manager receives challenge predicts whether people bring the next problem, measured at a later point in time rather than the same one.

The one randomised trial we found where training managers changed a hard outcome.

A meta-analysis of 335 leadership training studies covering 26,573 leaders identified the design features that separate development which transfers into the workplace from development which does not.

Five factors · 67.4% of the variance
Five things coaching changed in these executives. The one involving their own manager came last.
And half reported no change at all in how that manager communicated back.
Executive coaching: It works! Consulting Psychology Journal: Practice and Research, 60(1), 78–90. 114 executives and 42 coaches in one global pharmaceutical company. Principal component analysis, α = .95, isolated five factors accounting for 67.4% of cumulative variance. 98% gained insight into how their actions are perceived and 91% reported better results with direct reports, but only about 50% saw improvement in how their supervisor communicated back.
LimitsSelf-reported. One company. No control group. Variance in a questionnaire, not in outcomes.
HBA works on the system, not only the leader
Self-motivated managers still stall
The most intrinsically driven managers in the unsupported group did no better, and on some measures worse.
Wanting to grow is not the same as being able to do it alone.
Do I need coaching to achieve a learning goal? Coaching, goal orientation, and goal framing: A randomized control trial study. Current Psychology, 44(16), 13574–13590. Randomised controlled trial, 202 managers across 13 organisations, 43 external coaches.
LimitsThe mastery finding sits just outside significance (p = .087). One country. Self-rated at a single point.
HBA builds the support they are missing
686 executives · 300+ organisations
Asked in their own words what coaching changed, senior executives did not describe insight. They described running a team.
Executive leaders' perspectives on the impact of executive coaching on their leadership development. European Journal of Training and Development, 50(10), 127–145. 1,130 open-ended responses from 686 executives and 158 coaches across more than 300 organisations, predominantly Fortune 500, spanning North America, EMEA, Asia-Pacific and Latin America.
LimitsCoded descriptions, not measured outcomes. Lead author runs the firm studied.
ALLIANCE across difference.
BRIDGE across what we have learned to keep separate.
HOME for the whole.
OUR MANIFESTO
Homebridge® Alliance (HBA) exists to widen what consequential executive decisions take into account: people, relationships, systems, future generations, and the natural world.
By bringing analytical, emotional, and collective intelligence into alignment, we ensure the leader remains accountable while the decision takes more of reality into account.

GATEWAYS TO CHANGE
We do not sell pre-packaged programmes.
We solve specific leadership challenges.
Path I
The first read
A short, anonymous reflection that maps where you are before anything is proposed. Strictly private: no employer scoring, no record on file, and no unsolicited follow-up.
Play SignalPath II
The interactive learning practicum
An online simulator for senior cohorts that establishes objective behavioural baselines.
Hard-coded privacy and zero gamified badges.
Path III
The liminal residential intensive
Deep residential immersions for senior leaders changing direction or facing a critical transition. The Serpent Path is four days living in, then eleven weeks of integration back at work.
For individuals and organisations: Serpent Path for women & Whale Path (for mixed-gender cohorts). For Family/Intergenerational pathways: Swan (female), Eagle (male) · Raven (mixed-gender / inclusive).
Path IV
The bespoke enterprise evidence-to-change cycle
An evidence-backed integration of behavioural, wellbeing, and psychosocial-risk analysis to co-design structural workplace interventions and re-measure progress.
