Skills management in ESN: attracting, retaining and developing IT talent

Skills management has become a key factor in winning the battle for IT talent. In a context of shortage, every recruitment, every training and every development counts. HR decisions have a direct impact on the quality of assignments, customer satisfaction and profitability. Find out how to structure your approach and get concrete results with the analysis of Laurent Vandewalle, expert in agility and project management.

In an increasingly competitive employment market, digital service companies (DSCs) face a triple challenge: attracting the right profiles, retaining them over the long term and developing them rapidly.

Against this backdrop, certain skill families have become a priority for ESNs, particularly in high-demand technological areas such as the cloud, artificial intelligence, cybersecurity and data. But successful assignments no longer rely solely on technical expertise: soft skills such as leadership, communication, autonomy, adaptability and customer interaction management now play a decisive role in the quality of delivery and customer satisfaction.

Skills are still the foundation of NSE performance, but we still need to activate the right HR levers, using the right methods and with a measurable impact. So what are the winning strategies for HR and training managers? Here we take a look at tried and tested tools and monitoring indicators.

Attracting the right people: skills management in ESN starts with recruitment

Recruitment is the first step in skills management in an ESN. It's not just a question of filling a position in the short term (such and such an assignment), but of anticipating the key skills that the organisation will need in the months or years to come, in line with its customer strategy and its technological offering. From this stage onwards, sourcing, evaluation and selection decisions will determine the ESN's ability to build a skills portfolio that is coherent, scalable and aligned with market needs. What's more, the pressure on IT jobs means that we have to go beyond traditional recruitment methods.

HR data analysis

More and more NSEs are therefore relying on HR data analysis to make their recruitment decisions more objective and secure. Using data from past recruitment, performance on assignments, staff turnover and customer satisfaction, it is possible to identify the most suitable profiles, not only in technical terms, but also in terms of delivery and consultant attitude. This data-driven approach helps to better anticipate future needs, reduce recruitment errors and align skills more closely with the ESN's business strategy.

Delivery skills

In addition to their technical skills, ESNs now need to recruit people who can deliver value in a customer context. As a result, performance on assignments increasingly relies on delivery skills: project management, understanding business issues, customer communication, contractual follow-up, risk management and the ability to adapt to changing environments.

Identifying these skills at the recruitment stage helps to reduce risks on assignments (schedule slippage, customer tensions, failure to meet contractual commitments) and to secure the quality of delivery over the long term.

Skills management in ESN: concrete actions at the recruitment stage

The most successful ESNs combine several levers.

1/ Broad but targeted sourcing

• partnerships with schools
• active participation in tech communities (meetups, hackathons, forums)
• running an alumni network

2/ Predictive recruitment extended to delivery

Some players now include in their scoring models not only technical skills, but also criteria linked to delivery: ability to manage customer relations, autonomy on assignments, management of unforeseen events, respect for commitments and consultant attitude.

For example: a mid-size ESN reduced its trial period failure rate by 20 % using a skills + personality matching algorithm.

3/ Careful candidate experience

• shorter response times
• structured feedback
• transparency on milestones
• valuing commitment from the very first interview

In this way, recruitment becomes a structuring lever for skills management in ESN, rather than a simple operational act.

Building long-term loyalty: commitment, development and recognition

Recruiting is expensive. Building loyalty is therefore becoming a strategic imperative.

In ESN, loyalty does not depend solely on working conditions or pay. It relies heavily on consultants' ability to control their delivery understanding customer needs, managing priorities, solving problems on the job and maintaining a healthy customer relationship, even in tense situations.

Poor delivery control is one of the main causes of demotivation, stress and departures.

The 5 most effective levers observed in NSEs

1/ Personalised career plans

Suggest clear paths of progression:

• technical expertise
• team management
• project management

2/ Continuous upskilling and reskilling

Via hybrid training (e-learning, bootcamps, mentoring) on key technologies (cloud, AI, cybersecurity), but also on delivery skills.

Delivery skills :

• project management and operational management
• contract monitoring and commitment management
• communication and customer relationship management
• risk management and problem solving
• adaptability and management of priorities in a changing environment

3/ Mentoring and coaching

Pair a junior consultant with a senior one, not only for technical expertise, but also to develop posture and autonomy.

For example: an ESN with 500 consultants has set up an intergenerational mentoring programme. Visit Turnover has fallen by 8 points in two years.

4/ Stimulating internal projects

Participation in innovation labs, in-house hackathons or R&D assignments that strengthen the sense of belonging.

5/ Quality of life and working conditions (QLWC)

Telecommuting, flexible working hours, recognition, work/life balance, sustainable workload compared with fixed-term contracts.

A sustainable workload

In ESN, a sustainable workload is defined by a measurable balance between :

• delivery requirements (deadlines, quality, customer pressure)
• the legal and contractual framework of the fixed daily rate
• the consultant's real ability to maintain performance, commitment and health over the long term

So it's not a question of subjective feelings, but of steering by concrete benchmarks.

Rapidly developing talent: from «service provider» to «solution provider»

To remain competitive, ESNs must transform their talent into high value-added players.

This transformation does not rely solely on technical expertise. It involves gradual build-up of skills in delivery to be able to :

• analyse a customer need
• propose appropriate solutions
• anticipating risks
• arbitrate constraints (cost, lead time, quality)
• managing customer relations over the long term

4 best practices in ESN skills management

1/ Multidimensional assessments

Through annual interviews enriched with 360° feedback (customers, managers, peers) and explicitly integrating delivery criteria: quality of management, compliance with commitments, risk management, customer satisfaction and problem-solving skills.

2/ Progressive simulations

Give a technical consultant responsibility for supervising a small team, managing a batch of projects, managing a contractual scope or handling customer relations for a given assignment.

3/ Certifications and external recognitions

• Sponsor certifications (cloud, cybersecurity, SAFe®, ITIL®, etc.)
• Publicly highlighting successes

For example: at an ESN specialising in the cloud, 30 % of consultants have obtained Azure certification in less than a year, which has increased average invoicing by 15 %.

4/ Rotation of assignments

Offering cross-disciplinary courses to diversify experience and accelerate skills development.

Steering skills management in ESN: key indicators to objectify the HR impact

HR initiatives must be measured and controlled.

The the most relevant indicators in the NSE sector include :

• Turnover rate overall and by profile
• Retention rates at 12 and 24 months
• Rate of change/internal mobility
• Hours of training and successful certification
• Employee satisfaction (annual survey, internal NPS)
• Applicant to job conversion rate
• Average cost per recruitment
• Billability rate (proportion of an employee's time that is billed to the customer)
• Inter-contract rate (proportion of consultants without an assignment over a given period)
• Non-billable hours invested in training or innovation
• Customer satisfaction rate per consultant or per assignment
• Number of major incidents or customer escalations
• Meeting deadlines and contractual commitments
• Rate of rework or post-delivery corrections
• Difference between planned and actual workload on assignments

A 5-step action plan to structure skills management in ESNs

1. Mapping existing skills and future needs
2. Defining a realistic roadmap Prioritising high ROI levers (e.g. mentoring and certification)
3. Steering by small steps launch pilots, measure and adjust
4. Involving operational managers in skills development plans
5. Communicating widely internally highlighting success stories, sharing inspiring career paths, embodying the employer brand

In an environment where IT talent is in short supply, skills are no longer just an HR issue: they are a decisive competitive advantage for ESNs. Attracting, retaining and rapidly developing employees requires a combination of innovative practices, clear performance indicators and strong internal communication. The key to success? To view skills management as a strategic investment, serving the business, the customers... and the employees themselves.
