Tandra Wiley

Strategy becomes real in the operating model.

Nearly two decades leading operations, sourcing, and transformation inside a Fortune 8 healthcare enterprise and the companies around it — and building the leaders who sustain the result after the program closes.

Executive introduction

An operator who has carried enterprise scale, and a leader people follow twice.

Tandra Wiley leads where enterprise strategy meets the work: category and sourcing portfolios, global service operations, analytics, and the operating disciplines that decide whether a strategy survives contact with the organization. Most recently she was Vice President, Indirect Strategic Sourcing and Category Management at McKesson, a Fortune 8 healthcare company, with $4.4B of complex indirect spend in scope.

Her career has moved deliberately from the front line outward. She ran a 24×7 global technical support center spanning India, Canada, and the United States. She led business operations and performance for a $600M global unit, then built an analytics center-of-excellence strategy for a $1B business. She stepped outside the Fortune 500 to run operational excellence at a growing health-technology company, then returned to enterprise scale to lead sourcing policy, contract management, supplier diversity, and category strategy.

What repeats across those roles is not a single playbook. It is a way of working: diagnose the situation honestly, build the team the mission actually requires, earn the alliances that make execution possible, and leave the organization more capable than she found it. Eleven of her recommendations on record come from people who reported to her — a durable signal for a board weighing succession, culture, and leadership development.

Leadership at a glance

Six areas where her leadership has been tested at scale.

Each is drawn from a role she held, not a capability list. Figures are as stated in her professional record; outcome metrics still to be validated are marked.

Enterprise leadership

Fortune 8 category ownership

Led enterprise-scale indirect strategic sourcing and category management for a Fortune 8 healthcare organization, with $4.4B of complex spend and senior leadership teams in scope.

McKesson · 2021–2026

Operational transformation

Operating discipline outside the enterprise

As Vice President, Operational Excellence at Ingenious Med, held accountability for the processes, tools, and governance behind the company’s long-term financial sustainability.

Ingenious Med · 2018–2020

Customer & stakeholder experience

24×7 global service delivery

Directed a follow-the-sun technical support center — offshore India, nearshore Halifax, and domestic teams — providing continuous support to managed-services customers.

McKesson · 2008–2014

Strategic execution

Analytics as a decision discipline

Built an analytics center-of-excellence strategy for a $1B global business unit so that decisions and strategy were made against evidence rather than instinct.

Allscripts · 2017–2019

Team & talent development

A leadership pipeline, by design

Built and ran an enterprise summer internship program across two cohorts, leading 17 interns across separate projects and multiple locations. Eleven recommendations on record come from direct reports.

McKesson EIS · 2015–2017

Cross-functional influence

Governance that people actually use

Owned indirect policy, contract management, change management, supplier diversity, and the outside service worker program — the connective tissue between finance, legal, and the business.

McKesson · 2020–2021

Selected impact

Four situations, four different jobs.

The through-line is judgment about what each situation actually needed — not a repeated method.

Category leadership at Fortune 8 scale

McKesson · VP, Indirect Strategic Sourcing & Category Management · 2021–2026

Context

A Fortune 8 healthcare enterprise with $4.4B of complex indirect spend spread across categories, business units, and senior leadership teams with their own priorities and their own suppliers.

Challenge

Indirect spend of that size is rarely a sourcing problem first. It is an alignment problem: category strategy only works when the leaders who control the demand agree to be led.

Her role

Accountable for enterprise-wide category strategy and the senior leadership teams delivering it.

Action

Set category strategy against enterprise priorities rather than function-by-function convenience, and worked the relationships with business owners so decisions held outside the room where they were made — a preferred supplier program for governance and scalability, a workforce capacity model that cut cycle time by 30%, an 18-month rolling forecast by business unit for executive visibility, and executive-level scorecards to track dependencies and risk.

Outcome

$220M in total savings, including $70M in P&L impact, through strategic sourcing and cost optimization — a 14.7% ROI on sourcing investment. Supported a $353M enterprise IT transformation, retiring material technology debt. Employee engagement rose from 57 to 83 over the period.

Category leadership at this scale is enterprise leadership wearing a procurement title: the work is persuading autonomous leaders to act as one buyer.

Building the governance backbone before the strategy

McKesson · VP, Indirect Sourcing & Procurement Business Services · 2020–2021

Context

Responsibility for indirect policy, contract management, change management, supplier diversity, and the outside service worker program across the enterprise.

Challenge

These are the functions people notice only when they fail. They span legal, finance, HR, and every operating unit, and none of them can be fixed by authority alone.

Her role

Executive owner of the policy, contract, and compliance infrastructure that the category strategy would later depend on.

Action

Treated policy and change management as an adoption problem rather than a publication problem, and carried supplier diversity as an operating commitment with owners and reporting rather than an aspiration — launching Buy Smart, a companywide program to route spend through the right buying channels; building a hybrid on-shore/off-shore staffing and operating model; in-sourcing administration of the Outside Service program; standing up a Customer and Business Advisory Council; and resolving a Small Business Administration audit of the enterprise supplier diversity program with new process controls.

Outcome

Buy Smart brought spend under management to 94%. The hybrid staffing model saved $500K. In-sourcing the Outside Service program saved $300K while improving CSAT by 40%. The Advisory Council improved NPS and response rate, and the SBA audit closed with standards compliance established.

She took the unglamorous role first and the strategic mandate second — which is why the strategic mandate had something to stand on.

Operating discipline in a growth company

Ingenious Med · VP, Operational Excellence · 2018–2020

Context

A health-technology company where growth had outpaced the processes holding it together — a very different environment from a Fortune 8 enterprise.

Challenge

Install enough discipline to make the business durable without installing so much that it stops moving. Large-company process, applied literally, would have suffocated it.

Her role

Executive accountable for the processes, procedures, and tools underpinning long-term financial success and sustainability.

Action

Calibrated enterprise-grade operating practice down to what a company of that size could actually absorb and sustain, focused first on the processes closest to the customer relationship.

Outcome

In the first year: customer churn reduced by 50%, first-touch CSAT reached 96.6%, and NPS improved by 63%.

The experience that most distinguishes her from a career large-enterprise executive: she has had to earn operating discipline rather than inherit it.

Business performance discipline under real pressure

McKesson · Executive Director, Business Performance/Operations · 2015–2017

Context

Business operations and performance leadership for a $600M global unit, evaluated across seven customer touchpoints.

Challenge

The business was in an active search for strategic alternatives — the kind of period where performance and engagement usually slip.

Her role

Executive Director accountable for business performance, real estate optimization, and process governance.

Action

Directed the team to hold every KPI through the uncertainty, ran real estate optimization across 8 facilities, tightened change-control from contract signature to resource assignment, and built a governance process for virtual server accountability.

Outcome

Held employee engagement at 78% through the strategic-alternatives search. Cut contract-to-resource-assignment time by 47% and virtual server sprawl by 53% in 8 months. Ranked as a high potential leader 8 out of 9 years.

Performance discipline is easy to claim in stable years. This is what it looked like in an unstable one.

“Strategy is a set of intentions until somebody owns it, a date is attached to it, and the organization is capable of carrying it.”

Leadership principles

Four commitments, applied in order.

They are sequential on purpose. The team comes first because nothing downstream survives without it.

01

Build the right team

Select for the mission ahead, not the one just finished. Then make it possible for people to do the work you hired them for.

02

Match strategy to situation

Diagnose before you decide. Urgency, maturity, risk, and culture should change your approach — and if they don’t, you are applying a habit, not a strategy.

03

Create alliances

Enterprise work crosses boundaries you do not control. Influence, not authority, is what gets it across.

04

Accelerate everyone

Build capability, not dependency. If the organization slows down when you leave the room, you built the wrong thing.
