Improving Processes in Product Development: 5 Proven Best Practices

Why stable processes are the key to success

A good product idea alone is not enough. It takes stable, transparent and coordinated processes to turn an idea into a market-ready and economically successful product. Because even the most innovative solution can fail if it is developed in an inefficient environment. If responsibilities are unclear, information is scattered or decisions are delayed, it is not only the success of the project that suffers, but also motivation, innovative strength and market success. Teams work at cross purposes, important requirements are overlooked and valuable time is wasted on coordination, rework or error corrections.

Optimized processes, on the other hand, create the basis for productive, targeted development. They provide orientation, enable reliable planning and make interfaces between departments manageable. Instead of dealing with conflicts, teams can concentrate on what really matters: creating innovative solutions that focus on customer benefits.

Stable processes ensure:

• Clear responsibilities and fast decision-making channels: everyone knows what they are responsible for and who has the last word in case of doubt. This reduces friction and avoids unnecessary coordination loops.
• Efficient collaboration across departmental boundaries: Defined interfaces and a common language in the project reduce misunderstandings and break down silo thinking.
• Greater transparency and better planning: everyone involved has the same level of knowledge. This makes progress, risks and dependencies visible, which enables forward-looking management.
• Fewer frictional losses and costly loops: Clear processes and clean handovers mean that errors are identified and corrected at an early stage instead of dragging on to the end.

In short: stable processes are not an end in themselves, but the prerequisite for efficient, targeted and customer-oriented product development. This is especially true in an environment that is constantly changing.

Best practice 1: Understanding requirements as a common basis

The majority of all undesirable developments in product development can be traced back to unclear, incomplete or contradictory requirements. It is often not a lack of technical expertise or innovative spirit, but a lack of common understanding of what exactly should be developed and why. Different ideas, misunderstandings or implicit assumptions lead to products being developed that fail to meet actual needs.

This is why every successful optimization of development processes begins with professional requirements management. Requirements form the connecting foundation between customer needs, technical implementation and quality assurance. They are, so to speak, the common thread running through the entire project.

Success factors in requirements management:

• Systematic and comprehensible collection: Requirements should not be collected ad hoc or on impulse, but based on clear categories, formats and sources. This is the only way to create a reliable information base.
• Early involvement of all relevant stakeholders: The earlier the various perspectives, e.g. from sales, development, quality assurance or service, are taken into account, the lower the risk of later correction loops.
• Centralized, transparent documentation: With suitable tools, requirements can be recorded in a structured manner, versioned and made accessible to all stakeholders. This reduces misunderstandings and ensures a uniform view.
• Clear processes for review, approval and changes: Requirements are alive. This makes it all the more important to have defined processes for evaluation, approval and maintenance, including the traceability of all changes.

Professional requirements management not only creates clarity in the project, but also trust between those involved. It builds the bridge between vision and implementation, between idea, development and testing and is therefore a central foundation for stable and successful processes in product development.

Best practice 2: Cross-functional teams and clear roles

In many companies, specialist departments such as development, quality assurance, purchasing or product management still work largely in isolation from one another. Handovers are often rigid, the flow of information is fragmented and responsibilities are shifted back and forth. The result: misunderstandings, delays and a fragmented view of the product.

It has long been proven that complex challenges in product development are best solved by interdisciplinary teams, i.e. by people with different specialist backgrounds pulling together. This is exactly where cross-functional teams come in: They bring together all relevant skills and promote holistic responsibility for a result.

However, clear structures and rules are needed to ensure that this collaboration does not end in chaos:

• Clear allocation of roles and agreed responsibilities: Everyone in the team must know which tasks they are responsible for and who has the final say on which issues. This avoids duplication of work or gray areas.
• Common target definitions and measurable KPIs: When everyone is working towards the same goals, such as time-to-market, product quality or customer satisfaction, a shared understanding of success is created. KPIs make progress and responsibility visible.
• Regular exchange through established meeting structures: Agile or hybrid formats such as daily stand-ups, review meetings or retrospectives help to share information transparently, identify obstacles early on and continuously improve collaboration.

Cross-functional teams not only enable better coordination, but also bring different perspectives into the solution-finding process at an early stage. This increases the quality of decisions, reduces subsequent changes and also increases the identification of all those involved with the product.

Best practice 3: Iterative work according to the TwinPeaks principle

In theory, every product development begins with a complete set of requirements that are then systematically implemented. In practice, however, this is rarely the case, especially with innovative or technically complex products. Requirements are often incomplete, change during the course of the project or depend heavily on technical solutions that are not even known at the beginning.

This is precisely where the TwinPeaks principle comes in. TwinPeaks is an iterative approach in which requirements and architecture are developed in parallel and mutually refined. Instead of working through the disciplines sequentially, both “peaks”, i.e. “What should the system do?” and “What could it look like technically”, are created in close interaction and repeated loops.

The advantages of this approach are obvious:

Early feedback between desire and feasibility: specialist requirements and technical solution approaches are compared at an early stage, unrealistic expectations are recognized more quickly and technical opportunities are exploited at an early stage.
Quick reaction to new findings: As not everything has to be finally defined in advance, new requirements, findings or risks can be flexibly integrated without turning the entire project plan upside down.

• Early feedback between desire and feasibility: specialist requirements and technical solution approaches are compared at an early stage, unrealistic expectations are recognized more quickly and technical opportunities are exploited at an early stage.
• Rapid response to new findings: As not everything has to be finally defined in advance, new requirements, findings or risks can be flexibly integrated without turning the entire project plan upside down.
• Greater flexibility in dynamic project situations: An iterative approach is significantly more robust than classic, phase-oriented approaches, especially in the case of external dependencies, changing market conditions or uncertain framework conditions.
• Targeted identification of open points: The interaction between requirements and architecture reveals at an early stage for which product components there are still open issues and for which further requirements need to be formulated. This ping-pong process means that gaps become visible more quickly and can be closed in a targeted manner instead of only becoming apparent at the end.

Those who work according to the TwinPeaks principle not only reduce the planning effort at the start of the project, but also increase the quality and feasibility of the decisions because they mature step by step and are based on a continuous comparison between what and how.

Best practice 4: End-to-end digitalization and tool support

Many problems in product development have an inconspicuous but momentous origin: media disruptions. Requirements are collected in Word documents, architectures are sketched in Visio, tests are managed in Excel, while decisions are coordinated by email and approvals are stored somewhere in network drives. The result: information is scattered, versions are not traceable and correlations are barely recognizable. This is exactly where the process gaps arise that later lead to friction losses, errors and a high coordination effort.

Modern software solutions such as reqSuite® rm help to close these gaps and digitally map the entire development process, from requirements to testing. The advantage: all relevant information is centrally available, interlinked and controllable via clearly defined workflows.

Specifically, you benefit from tool support:

• Central management of all requirements, dependencies, versions and releases: No more isolated solutions, instead all content is consistently documented and traceable at all times.
• Linking with test cases, components and stakeholders: Relationships between functional requirements, technical components, tests and people involved are made explicitly visible and controllable.
• Automated notifications and workflows: Stakeholders are actively informed about changes, approvals or tasks, which reduces manual coordination and speeds up decisions.
• Intelligent assistance functions for quality assurance: modern tools such as reqSuite® rm offer AI-based checks for completeness, consistency or potential conflicts and therefore represent real added value for structured projects.

Digitized processes are not only faster and more transparent, but also much more robust in the face of human error. They make it easier to comply with standards, implement changes in a controlled manner and reliably scale projects, which is particularly important in growing or highly regulated companies.

Best practice 5: Establish continuous improvement

Even the best process is never finished, as framework conditions, technologies and requirements are constantly changing. Companies that want to make their product development successful in the long term therefore need more than one-off optimizations. They need a practiced culture of continuous improvement.

This means that processes and structures are regularly reflected upon, scrutinized and adapted. Not out of actionism, however, but always with the aim of systematically improving. This attitude distinguishes mature organizations from those that only react to problems when it is already too late.

Important elements of this continuous improvement are:

• Retrospectives after project phases or releases: In short, structured reviews, the team analyzes what went well, where things went wrong and what should be done differently in the future.
• Systematic collection of feedback from all roles: Not only developers or project managers, but also specialist departments, testers and external stakeholders should be listened to regularly, because every perspective counts.
• Key figure-based analysis: Data such as throughput times, error rates or change requirements help to objectively identify weak points and derive targeted improvement measures.
• Courage to change: A genuine culture of improvement requires openness, especially when it comes to uncomfortable questions.

Only those who regularly question the status quo can remain resilient and innovative in the long term.
Continuous improvement is therefore not an optional extra, but a key success factor in a changing world. Those who continuously reflect remain resilient, innovative and competitive.
