The authors discussed the PD organization structure issues with the management of multiple large biotech and biopharmaceutical companies involved in therapeutic protein manufacturing (1). The focus was on the following:
While all companies have their own structures, there are general concepts and patterns that are reproducible. Using the gathered information in combination with the authors' own experience, organizational models were developed that cover a broad spectrum of options spanning from complete decentralization to full centralization. These models do not represent the structure of any particular company, but capture the essence of the existing opportunities.The existing structures are not static but continue to evolve, thus reflecting the progress and the specifics of each organization. Despite many differences, often resulting from the personal preference of top management, there is a clear trend towards global alignment.
Most companies have separate MS and PD functions. Furthermore, the MS groups are always colocated with the manufacturing departments they are supporting. Because this model is common and offers some important advantages, the authors considered it as a standard in the analysis. The advantages of this approach include speed of response to urgent manufacturing needs and shielding of PD from short-term daily problems in the plant, so that resources are focused on long-term strategic projects and innovation (2). In some cases, a central MS group is responsible for the coordination and standardization between the distributed MS networks.
On the other hand, PD is responsible for larger life-cycle management projects, development and transfer of new processes, new technology platforms, and manufacturing support of complex projects requiring intense experimental and analytical work. The PD group can be centralized or decentralized, residing at several sites that provide remote services to various internal customers.
While a definition of the responsibilities of MS and PD is helpful, it is difficult to define a clear line between the two. Accepting a certain level of healthy overlap and ambiguity is practical, because this can serve as a bridge between the two functions, thus preventing dangerous gaps. The complexity of biotech manufacturing results in a continuum of projects, some of which cannot be clearly allocated to only MS or PD.
The coordination between MS and PD is a critical element of the biotech enterprise. Structurally, these groups exist as independent departments under different management. As such, it is essential that their activities, procedures, objectives, priorities, and methodology be aligned. This alignment can be achieved by properly designed business processes involving both organizations, including but not limited to joint teams, committees, periodic reviews, and symmetrical functional structures. Proper alignment allows for an optimal response to rapidly changing priorities, fluidity, coordinated resource allocation, and global utilization of knowledge generated at different locations.
