Built on a decade of doing the hard work.

Signal is Josh Greencroft, a senior delivery leader with over a decade of experience across UK central government.

I've delivered large-scale digital programmes at DEFRA, HMRC, MoJ, DHSC, UKHSA, and DESNZ, operating at programme and portfolio level. I established DEFRA's first Delivery Centre and have led programmes from Discovery through to Live across the GDS delivery lifecycle.

The cause of delivery failure is rarely the team. It is almost always the conditions around it. Signal exists to change that.

I operate at programme and portfolio level: leading multiple teams simultaneously, managing multi-million pound budgets, and engaging at Director and Board level. I'm equally comfortable parachuting into complex, fast-moving environments and building delivery capability from the ground up.

My background spans programme delivery, portfolio management, product ownership, and agile coaching. I bring rigour to governance without losing sight of outcomes, and I'm known for building high-performing teams in pressurised environments. I'm experienced across the full GDS delivery lifecycle from Discovery through to Live, and comfortable working within GDS assessment frameworks, Cabinet Office governance, and spend controls.

Governance is rarely the only cause of failure. Misaligned incentives, unclear ownership, weak leadership, poor architecture, and ineffective governance often reinforce each other. Zero Drag Delivery does not blame any single factor. It focuses on identifying and removing friction wherever it exists, whether that is in the team, around the team, or in the political and organisational system the team is operating inside.

I take on a small number of fractional engagements where organisations need senior delivery expertise without a full-time hire, previously for DESNZ and DLUHC, and open to similar arrangements in central government and arm's length bodies.

01
Understand the problem before you build the solution

Genuine Discovery means understanding a problem before committing to a solution. Teams that skip it almost always build the wrong thing. The output is not a solution — it is enough confidence to know one is worth pursuing. Pointing a team at a predetermined answer and asking them to work backwards is not Discovery. It is waterfall with a GDS wrapper.

02
Prepare the environment before the team lands

Before a team starts, make the decisions that can reasonably be made. Set guardrails, agree constraints, resolve dependencies. This is not designing the solution upfront — it is removing avoidable ambiguity before it becomes expensive. Teams that arrive to a prepared environment can focus on delivery. Teams that do not spend months navigating governance that should have happened before they landed. Stock the fridge. Then let the team cook.

03
Governance enables, it does not control

Good governance helps the right people make good decisions, as close to the work as possible. It does not make those decisions itself. When teams spend significant time producing documents nobody meaningfully reads, governance has tipped into control. Clear ownership matters too: when nobody has authority to decide and be trusted to have decided well, governance becomes a substitute for leadership.

04
Loose coupling at every level

Tightly coupled organisations build tightly coupled services. When every decision needs consensus from half the organisation, delivery slows to the speed of the slowest dependency. Loose coupling is not the absence of dependencies — it is the deliberate reduction of unnecessary ones. Loosely coupled teams with clear outcomes and trusted autonomy build services that are more modular, adaptable, and resilient.

05
Outcomes over activities, always

The most valuable programmes succeed because they changed what an organisation was capable of, not because they cut costs. Outcomes-led thinking asks: can users achieve what they need more easily? Can services adapt to changing policy? Activities are inputs. Outcomes are evidence that something has actually improved.

06
Platforms and capability emerge through delivery

The most durable digital infrastructure is built by teams that deliver services deliberately, leaving reusable building blocks behind them. A capability not actively in use is a hypothesis, not an asset. The first service proves it works. The third to fifth prove it is worth standardising. Build only what you have evidence for. Invest heavily once reuse has been demonstrated.

07
Be comfortable with uncertainty. It is the condition, not the problem

Reaching for a complete picture before starting is understandable. In complex environments it is usually counterproductive. Uncertainty is not a problem to solve before delivery begins — it is the condition in which delivery happens. Clear ownership and delegated authority make uncertainty manageable: when things change, the right people have the authority to respond.


Three ways to work with Signal.

Engagements are typically fractional, two to three days a week, giving clients access to experienced delivery leadership at the moments it matters most, without the overhead of a permanent appointment.

Fractional delivery leadership

Embedded senior delivery support for programmes and teams, typically two to three days a week. Ideal for organisations that need experienced leadership during a critical phase of delivery without committing to a full-time hire.

Typically 2–3 days per week, ongoing

Advisory and assurance

An independent assessment of delivery conditions, governance structures, and team ways of working, with clear recommendations for improvement. Useful at the start of a programme, at a point of difficulty, or as an external sense-check on an existing approach.

Fixed-scope project engagement

Workshops and facilitation

Half-day or full-day sessions for senior leaders and delivery teams, built around the Signal philosophy. Topics include preparing conditions for delivery, governance that enables rather than controls, and building high-performing teams in uncertain environments.

A philosophy built from the inside out.

The first thing many experienced people will think when they read this is: I have heard this before. Discovery. Empowered teams. Outcomes. Autonomy. Iterative learning. This has been the agile conversation since 2005.

That reaction is understandable. But it misses a distinction that matters. Most agile thinking focuses on the team — how it works, how it plans, how it iterates. Zero Drag Delivery is not primarily concerned with what happens inside the team. It is concerned with what happens around it. Governance. Funding models. Decision-making authority. Organisational design. Leadership behaviour.

Teams rarely fail because they do not understand agile. They fail because the environment around them makes success structurally impossible. Zero Drag Delivery addresses the system, not just the team. That is the distinction.

DEFRA

Building DEFRA's first Delivery Centre

When I joined DEFRA as Delivery Centre Lead, there was no delivery centre. Working with delivery managers, programme leads, and technical colleagues, we built it together. Eight teams, reporting to Director-level governance, delivering change critical to the UK's biosecurity as part of the Delivering Sustainable Futures programme. The challenge was not just delivery. It was creating the conditions for delivery: establishing guardrails, building assurance capability, standing up governance that enabled rather than blocked, and scaling a programme that had previously struggled to move at all.

By the time I moved into the Delivery Group Assurance Lead role, the centre had become the model for how DEFRA approached programme delivery.

Ministry of Justice

Delivering the No Fault Divorce service

The No Fault Divorce service was the biggest change to UK family law in fifty years. I led delivery from Discovery to national launch on 6 April 2022. Two teams. Eighteen people. A service that would handle over 150,000 cases annually. The challenge was not technical. It was stakeholder management at scale, across Policy, Legal, Operations, and the Judiciary, and protecting the team from outside interference so they could focus on building something that actually worked.

The service launched on time. It works.

NHSX

The Emergency Volunteering Service

In March 2020, NHSX needed a platform to coordinate emergency volunteers as part of the COVID-19 response. Working as Deputy Project Lead and Delivery Manager, the team took the service from inception to production-ready MVP in two weeks, and to handover in six. A blended team of twenty people from NHSX, NHS Business Services Authority, PA Consulting, and GDS. As it turned out, the impact of COVID-19 on the care workforce was not as severe as feared, and the service was not deployed at scale.

Delivery success is not always measured in users. Sometimes it is measured in readiness.

UKHSA

Delivering under political pressure

The UKHSA COVID-19 App operated in one of the most politically pressurised delivery environments I have experienced. Policy changed weekly. Decisions that would take months in a normal programme had to be made in days. The only way to keep delivery moving was to make political decisions visible and explicit, to surface them quickly, escalate them cleanly, and insulate the team from the noise long enough to ship.

That is not a methodology. It is a judgement call made under pressure, repeatedly, over months.
