Transformation of supplier management:

How a German fibre optic company revolutionized purchasing, IT and rollout with a modular framework agreement.

Introduction

A new, modular general contractor framework agreement enables scalable supplier management and the achievement of growth targets

A leading German fiber optic company was facing a business-critical challenge. The lack of controllability and reliability of its general contractors (GCs) threatened the entire growth strategy. Project-based individual contracts, fluctuating prices and non-transparent project progress made the long-term management of the entire business operation considerably more difficult. The company urgently needed a structured solution to get out of the chaos of individual contracts and establish sustainable, holistic supplier management.

Challenges

Difficult starting position for a successful turnaround

The initial situation was characterized by several critical problem areas: general contractors were unable to complete negotiated projects successfully and on time; in particular, the planned activation of house transfer points (HPs) to house connections (HAs) regularly failed or was subject to considerable delays. Individual contracts were concluded for each project, resulting in late renegotiations and cost volatility. To make matters worse, there were sometimes considerable discrepancies between high-level design (HLD) and low-level design (LLD), there was hardly any transparency regarding ongoing projects and there were no incentives for general contractors to quickly convert HPs into HAs.

Particularly problematic: a large management consultancy had previously failed to implement a new, standardized framework agreement. The centralized management with simultaneous integration of all relevant departments and employees simply did not work.

Solution approach & procedure

The right structure and anchoring at CEO level and Transformation Office as the key to success

The transformation began with a comprehensive status quo analysis and systematic categorization of all topics. Responsible departments were identified and directly involved in defining objectives and scheduling. A new governance structure was established to manage the program at the highest level and avoid the failure of the previous consulting initiative.

The initial focus was on the step-by-step definition and finalization of the contract content with the close involvement of all relevant stakeholders and decision-makers. This enabled open points to be dealt with quickly and an initial version of the contract to be drawn up. At the same time, the contract process was used to create transparency regarding implementation gaps in the specialist areas and a clear implementation roadmap was developed.

The first version of the contract was then discussed and negotiated with prioritized JVs. An accompanying training program for departments and JVs was set up to ensure the successful implementation of the new content and procedures. This resulted in a total of three program streams with contract, business implementation and capability building.

Three critical success factors ensured the breakthrough. Anchoring at CEO level with a dedicated MSA task force of internal and external experts ensured daily coordination and weekly SteerCo updates with all C-level stakeholders. Clear process responsibility in the specialist departments through single points of contact (SPoCs) established an ownership mindset for end-to-end processes. Finally, the modular contract structure, clear negotiation processes, standardization and the development of expertise in the specialist departments rounded off the successful approach.

Results & successes

A modular system approach delivers the success that was previously lacking

The transformation was a resounding success: the company developed a completely new, efficient and modular framework contract in German and English that seamlessly integrated all of the company’s business-critical programs. The successful support of the specialist departments in the parallel development and elaboration of new topics and their integration into the contract ensured that all strategic initiatives were aligned.

The signing of contracts with existing and new suppliers marked the start of a new era in supplier management. The start of implementation in the specialist departments was accompanied by coaching for the teams to ensure successful implementation.

The new framework agreement now offers a transparent service catalog with fixed and reduced prices, short order cycles with on-demand call-offs and regional key suppliers with targeted control levers. The company benefits from significantly improved controllability, a close link between payments and project progress as well as stronger incentives for rapid project progress and a flexible response to market changes.

The proven business results, controlled risk management and modular system approach make the MSA a tried-and-tested blueprint for fiber optic providers. This case study impressively demonstrates how a well thought-out transformation strategy, consistent management and structured implementation can successfully overcome even the most complex challenges in supplier management.
