Clinical Data Management Jobs: A Career Guide -

Introduction: The Gateway to a Career in Clinical Data Management

Clinical research is a foundational pillar of modern medicine, enabling the development of life-saving therapies and a deeper understanding of human health. While a clinical trial’s success is often attributed to the breakthroughs of researchers and physicians, the integrity and reliability of its findings rest upon a critical, often unseen, discipline: Clinical Data Management (CDM).

Clinical Data Management is the comprehensive process of collecting, validating, and managing data from clinical trials to ensure it is of the highest quality for statistical analysis, regulatory submission, and informed medical decision-making. In an era where a single Phase III trial can generate millions of data points, the role of CDM has evolved from a simple data entry function to a strategic discipline that protects the integrity of the entire study and accelerates the time it takes for new drugs to reach the market.

This guide is a definitive resource for life science graduates, providing a practical, factual, and authentic overview of a career in Clinical Data Management. It is structured to take a learner from foundational principles to advanced, real-world applications. The following chapters will demystify the CDM lifecycle, explore essential workflows, detail critical regulatory requirements, and look toward the future of the field with emerging trends like Real-World Evidence (RWE), Risk-Based Monitoring (RBM), and the integration of Artificial Intelligence (AI).

The Fundamentals of Clinical Data Management

Defining the Core: What is Clinical Data Management?

Clinical Data Management is a critical phase of clinical research, designed to generate high-quality, reliable, and statistically sound data from clinical trials. The primary objective of CDM is to minimize errors and missing data, thereby providing a complete and accurate dataset for analysis. This process involves the collection, cleaning, and management of subject data in strict compliance with global regulatory standards.

The modern CDM process has undergone a significant transformation from its manual, paper-based, and error-prone origins. Today, data is collected from a wide array of sources, including traditional patient visits, clinical sites, and laboratories, as well as modern, disparate sources like Electronic Health Records (EHRs), sensors, imaging, and direct patient-entered data. A key challenge in this environment is managing both structured data (e.g., lab values) and semi-structured or unstructured data (e.g., physician notes), which is often inconsistent and prone to errors.

The entire CDM process is structured around a lifecycle with three main stages: Study Set-Up, Study Conduct, and Close-Out. The Study Set-Up stage lays the foundation for a clinical trial, while the Study Conduct stage focuses on continuous data review and cleaning. Finally, the Close-Out stage concludes all data management activities in preparation for analysis and regulatory submission.

The Vital Role of the Clinical Data Manager (CDM)

A Clinical Data Manager (CDM) is a specialist responsible for ensuring the accuracy, integrity, and security of data collected during clinical trials. The position is central to the success of a clinical research project, with responsibilities that span the entire trial lifecycle. A CDM’s role is not limited to technical tasks; they act as a strategic partner, transforming raw data into validated information that supports drug development and regulatory submissions.

Key responsibilities of a CDM include:

Drafting the Data Management Plan (DMP): A comprehensive plan outlining all data management activities, from acquisition to data review and preparation for analysis.
Designing Case Report Forms (CRFs): Creating forms that are clear, relevant, and actionable for data collection.
Creating and Managing Databases: Designing and implementing clinical databases that are well-structured and aligned with the study protocol.
Implementing Quality Control: Ensuring protocol and regulatory compliance throughout the trial.
Data Validation and Cleaning: Implementing processes to monitor data quality, identify discrepancies, and resolve queries.
Preparing Reports: Generating reports and data summaries for analysis and for the study team.

The role of a Clinical Data Manager has evolved considerably. Historically, the position was primarily administrative, focused on manual data processing. However, with the explosion of data volume and the advent of sophisticated technologies, the CDM has become a critical strategic partner who helps accelerate timelines and reduce costs through effective management and optimization of protocols. By designing relevant and clear databases, the CDM facilitates the work of researchers and contributes directly to scientific progress and public health. This shift means that a CDM must not only be technically proficient but also possess a deep understanding of the overarching research objectives.

Essential Skills for Success: Technical vs. Interpersonal

A successful career in Clinical Data Management requires a unique blend of technical expertise and interpersonal skills. Technical competencies are the foundation of the role, enabling a professional to perform daily tasks with precision and efficiency. These include:

Proficiency in Data Management Systems: Familiarity with industry-standard software like Electronic Data Capture (EDC) systems (e.g., Medidata Rave, Oracle Clinical) is essential for efficient data collection, cleaning, and analysis.
Medical Coding Knowledge: An understanding of medical coding and the dictionaries used, such as MedDRA and WHO-DD, is a core competency for standardizing clinical data.
Regulatory Knowledge: A strong grasp of regulatory guidelines like ICH GCP and 21 CFR Part 11 is critical for ensuring compliance and maintaining data integrity.
Data Programming: While not always required for entry-level positions, familiarity with programming languages like SAS, Python, SQL, or R is a significant asset for data manipulation, analysis, and reporting.

Beyond technical aptitude, the role requires a robust set of soft skills. A CDM must be detail-oriented and thorough, with the ability to manage complex information and adhere to strict deadlines. Excellent problem-solving and analytical skills are necessary for identifying data trends, outliers, and inconsistencies. Furthermore, strong communication and interpersonal skills are vital, as the role involves collaboration with a diverse team of investigators, statisticians, and regulatory authorities. A CDM serves as a communication bridge, translating data issues for a variety of stakeholders.

A comprehensive understanding of these requirements is essential for aspiring CDM professionals. The following table provides a clear overview of the key responsibilities and the skills required to perform them effectively.

The Clinical Data Management Lifecycle: A Practical Workflow

The CDM lifecycle is a systematic process that ensures data quality from the start of a trial to its conclusion. It is divided into three distinct phases, each with its own set of critical activities.

Phase I: Study Start-Up

The Study Set-Up phase is the foundation of a clinical trial, where all data management systems and procedures are planned and put into place.

Interpreting the Protocol and Developing the Data Management Plan (DMP)

The first step is a thorough review of the study protocol to understand its objectives, study endpoints, and data collection requirements. Based on this, the Data Management Plan (DMP) is developed. The DMP is the central “blueprint” for all CDM activities, detailing the systems, data collection tools, medical coding dictionaries, and procedures for data review, cleaning, and preparation for analysis.

Designing the Case Report Form (CRF) and Electronic Data Capture (EDC) System

The Case Report Form (CRF) is the primary instrument used to collect study-specific data from patients. In modern trials, this takes the form of an electronic CRF (eCRF) within an EDC system. The design of the eCRF is a crucial task, as it must be user-friendly, unambiguous, and a direct reflection of the protocol. Best practices include avoiding open-ended questions and using coded lists or controlled terminology to limit answers, which reduces data entry errors and simplifies future analysis.

Once the CRF is designed, the EDC system is built based on its structure. This involves programming the data entry screens, defining data fields, and setting up the system for the trial. It is important to note that the system must also enforce user access controls, providing unique user IDs and role-based permissions to ensure an audit trail is maintained for all activities.

Database Build, Validation, and User Acceptance Testing (UAT)

After the database is built, it undergoes rigorous validation. This involves programming validation rules, also known as “edit checks,” to automatically identify flawed data or discrepancies. These checks are designed to flag data that is missing, inconsistent, out of range, or incompatible with other data points or study parameters. The goal is to catch errors at the point of data entry, reducing the need for extensive manual data cleaning later in the trial.

The next step is User Acceptance Testing (UAT), a critical process where the entire study team reviews and tests the database against both valid and invalid test cases. This ensures that all user requirements are met and that the programmed edit checks fire as expected. Only after successful UAT is the clinical database released into production and approved for use.

Phase II: Study Conduct

Once the database is live, the Study Conduct phase begins. This is the main period of data collection and cleaning, with a continuous focus on quality, accuracy, and completeness.

The Data Cleaning Engine: Edit Checks and Validation Rules

Data cleaning is the process of identifying and resolving data discrepancies to ensure the integrity of the data. During the study, the edit checks programmed in the Set-Up phase fire automatically when data is entered, electronically generating queries for the site staff to resolve. A CDM’s role in this stage is to continuously review the data and the system’s automated checks.

It is important to understand that the purpose of data cleaning extends beyond correcting individual errors. By analyzing key performance indicators (KPIs) like the query rate per CRF page or the volume of queries from specific data points, a CDM can identify recurring issues and potential underlying problems, such as unclear CRF design, inadequate site training, or issues with a data source. This allows for proactive, data-driven interventions to improve the overall quality of the trial’s data.

Query Management: The Art of Discrepancy Resolution

Query management is the core process of resolving the discrepancies flagged by the edit checks or manual review. It serves as a communication bridge between data managers and site investigators.

The query management workflow typically involves the following steps:

Detection: Identifying the discrepancy through automated edit checks or manual data review.
Generation: Creating a query with clear, concise, and jargon-free text that asks for clarification or correction.
Assignment: The query is assigned to the relevant site staff for review and resolution.
Resolution: The site staff corrects the data or provides a satisfactory response, at which point the query is closed.

Effective query management is essential for data integrity and trial efficiency. Metrics such as “Query Turnaround Time” and “Query Volume and Frequency” are tracked to evaluate the process and identify slow-moving queries or sites with an unusually high number of data issues, which may signal a need for re-training or process review. All query management activities are tracked in an audit trail, which provides a chronological record of who raised the query, when, to whom it was assigned, and how it was resolved.

The Role of Medical Coding in Data Standardization

Medical coding is the classification of free-text, verbatim terms reported by investigators (e.g., adverse events, medical history, concomitant medications) into a standardized, statistically quantifiable terminology. This process is crucial because it ensures that data from different investigators at multiple sites is interpreted uniformly and can be aggregated for meaningful analysis and reporting for regulatory submission.

The two most commonly used medical coding dictionaries are:

MedDRA (Medical Dictionary for Regulatory Activities): The ICH-developed and recommended dictionary for coding adverse events and medical history terms. It is maintained and published bi-annually by the Maintenance and Support Services Organization (MSSO).
WHO Drug Dictionary (WHO DD): A comprehensive source used for coding medications. It is maintained and published quarterly by the Uppsala Monitoring Centre (UMC).

The industry standard for medical coding is a hybrid approach. An “auto-encoder” first programmatically matches verbatim terms that have an exact or close match in the dictionary. Terms that fail this auto-coding process are then manually coded by a coding specialist who uses the dictionary’s search feature to find the most appropriate term. If a term is unclear or has insufficient detail (e.g., “ulcer” without a location), a query is raised to the site to obtain the necessary clarification from the investigator before a code can be assigned. The entire coding process, including all manual changes, is documented with an audit trail to ensure traceability.

Serious Adverse Event (SAE) Reconciliation

During the study, a critical data management activity is Serious Adverse Event (SAE) reconciliation. This involves the systematic process of comparing the SAE data reported in the clinical database with the corresponding data in the safety database. The purpose is to ensure that all SAEs are accurately and consistently captured across both systems, with no discrepancies or omissions.

Phase III: Study Close-Out

The final phase of the CDM lifecycle focuses on preparing the data for final analysis and regulatory submission.

Quality Control (QC) and Final Data Review

As the trial nears its end, a final quality control review is performed on the entire dataset to ensure it is complete, accurate, and consistent. All open queries must be resolved and closed before proceeding to the next stage.

Database Lock: The Point of No Return

Database lock is a major milestone in a clinical trial. This activity signifies that all data cleaning and validation activities are complete, and the database is deemed ready for statistical analysis. Once a database is locked, no further changes can be made to the data. This irreversible action is crucial for maintaining the integrity of the data and ensuring that the final statistical analysis is performed on a consistent and verifiable dataset.

Preparing Final Datasets

Following database lock, the final, clean dataset is prepared for regulatory submission. This often involves transforming the data into a standardized format, such as the Study Data Tabulation Model (SDTM) and other CDISC standards, which are required by regulatory bodies like the FDA.

The table below provides a practical overview of common data validation checks used in the Study Conduct phase.

Check Type	Description	Example
Range Check	Verifies that a data value falls within a predefined, acceptable range.	A patient’s age must be between 18 and 65. A blood pressure reading must be within a plausible clinical range.
Format Check	Ensures data adheres to a specified format or pattern.	A date of birth must be entered as MM/DD/YYYY. A patient ID must be a specific alphanumeric format, e.g., “PAT-123.”
Logic Check	Compares data across different fields to ensure it adheres to the study protocol and makes logical sense.	The “Date of Diagnosis” must be on or before the “Date of Enrollment”.¹⁷ If a patient’s gender is male, pregnancy-related questions should not be enabled.
Consistency Check	Verifies data coherence across different forms or visits.	A patient’s weight at Visit 2 should not be drastically different from the weight at Visit 1 unless a medical reason is documented.
Completeness Check	Ensures that all mandatory fields on a form have been filled.	All fields marked as “required” are complete before the form can be saved.¹⁷

The Regulatory Compass: Navigating Compliance

Regulatory compliance is a non-negotiable aspect of Clinical Data Management. It provides a framework that ensures the ethical conduct of trials, protects patient rights, and guarantees the credibility of the data.

Good Clinical Practice (GCP): The Guiding Principles for Data Quality

Good Clinical Practice (GCP) is an international ethical and scientific quality standard that applies to the design, conduct, recording, and reporting of clinical trials. Developed by the International Council for Harmonisation (ICH), GCP is a unified framework that facilitates the mutual acceptance of clinical trial data by regulatory authorities worldwide.

The purpose of GCP is two-fold: to protect the rights, safety, and well-being of trial participants and to ensure the integrity and credibility of the clinical data. The ICH E6(R3) guideline, an updated version of the standard, introduces a more flexible, risk-based approach to clinical trial conduct. It encourages the use of innovative technologies and operational approaches, such as decentralized elements and Real-World Data (RWD), while emphasizing a “quality by design” culture. This means that the quality of the trial should be proactively designed into the protocol and processes from the very beginning, ensuring that data is fit for its intended purpose.

21 CFR Part 11: Ensuring Trust in Electronic Records and Signatures

Within the United States, the Food and Drug Administration (FDA) has specific regulations for electronic records and signatures. 21 CFR Part 11 mandates that electronic records and electronic signatures are considered legally equivalent to paper records and handwritten signatures when they meet a specific set of requirements. This regulation is a cornerstone of modern, paperless clinical trials.

The core requirements of 21 CFR Part 11 include:

System Validation: All computer systems used for regulated activities must be validated to ensure they are accurate, reliable, and perform as intended. This process provides confidence that the system will produce trustworthy records consistently.
Audit Trails: The system must generate secure, computer-generated audit trails that record the date, time, user identity, and the action that creates, modifies, or deletes an electronic record. This log is unalterable and must be retained for the required regulatory period, ensuring data traceability and transparency.
User Access Controls: The system must limit access to authorized individuals. This involves using unique user accounts and a permissions structure that grants access only to the functions necessary for a user’s specific role. The principle of “least privilege” is key, and no two individuals should ever share the same credentials.
Electronic Signatures: Electronic signatures must be as secure and attributable as handwritten signatures. They must include the printed name of the signer, the date and time of the signature, and the meaning of the signature (e.g., “Reviewer,” “Approver”).

These regulations are not just abstract legal requirements; they are the foundation of day-to-day CDM operations. Every action taken in an EDC system is subject to these rules. The audit trail, for example, is not just a regulatory checkbox; it is the digital “paper trail” that ensures accountability and provides proof that no unauthorized or fraudulent changes were made to the data. A CDM professional’s work directly contributes to upholding these standards, which is critical for ensuring the validity of a trial’s results and protecting public health.

Global Data Privacy: Adhering to HIPAA and GDPR

In a globalized clinical research environment, data privacy is paramount. Two of the most significant regulations a CDM professional must be aware of are HIPAA and GDPR, which protect sensitive patient information.

HIPAA (Health Insurance Portability and Accountability Act): This is a U.S.-specific regulation that focuses on the protection of Protected Health Information (PHI). PHI includes medical records, lab results, and demographic data that is linked to healthcare services.
GDPR (General Data Protection Regulation): This regulation applies to any organization, regardless of location, that handles the personal data of European Union (EU) residents. GDPR has a much wider scope than HIPAA, protecting all forms of personally identifiable information (PII), including health data, IP addresses, genetic data, and location details.

While they differ in scope, HIPAA and GDPR share a commitment to data security and patient privacy. Both frameworks require controlled access to sensitive data, robust encryption for data at rest and in transit, and regular risk assessments to identify potential vulnerabilities. For multinational clinical trials, CDM professionals must navigate the requirements of both regulations, which may require robust systems that address GDPR’s broad data protections alongside HIPAA’s healthcare-specific rules. The need to maintain data security across international borders and ensure proper consent for data use is a critical responsibility that is often disclosed on informed consent documents.

Audit Trails: The Immutable Record of Accountability

An audit trail is a secure, time-stamped, and unalterable record that tracks every change made to electronic data throughout its lifecycle. It serves as a digital “paper trail” for electronic records, providing an immutable log of who accessed or modified the data, when it happened, and what changes were made.

The value of a robust audit trail is most apparent when an issue arises. For example, if a regulatory authority questions an inconsistency in a patient’s record, the audit trail provides a clear and verifiable history of every action taken. It can show whether a missing dosage was an accidental omission or an intentional removal, and it can trace any alterations back to the user who made them. This level of transparency is essential for regulatory compliance, preventing fraud, and ensuring accountability among all stakeholders.

Modern EDC systems are now leveraging Artificial Intelligence (AI) to optimize audit trail review. Instead of manually sifting through massive datasets, AI can be used to automatically identify unusual patterns, such as after-hours data entry, a site with a significantly higher rate of data modifications, or suspicious patterns in patient-reported data. This AI-powered approach enables teams to focus their investigative efforts on high-risk areas, improving efficiency and data oversight.

Modern Paradigms and the Future of CDM

The landscape of clinical research is constantly evolving, driven by new technologies and a growing demand for data-driven insights. Modern Clinical Data Management must adapt to these changes, embracing new paradigms to remain at the forefront of medical research.

From Efficacy to Effectiveness: The Rise of Real-World Evidence (RWE)

Clinical trials have long been considered the “gold standard” for assessing the safety and efficacy of new medical interventions. They are meticulously designed, prospective studies that evaluate a product under ideal, controlled conditions. However, their strict inclusion/exclusion criteria often result in homogeneous patient populations that may not fully reflect the real world.

In contrast, Real-World Data (RWD) is collected from observational or non-experimental sources that reflect routine clinical practice. These sources include electronic health records (EHRs), medical claims, patient registries, and data from wearable devices. Real-World Evidence (RWE) is the clinical evidence generated from the analysis of RWD.

The value of RWE is that it provides complementary insights into a product’s effectiveness and safety in a broader, more diverse patient population and over a longer period. It can provide a more accurate picture of how a therapy is used in routine care and can help identify rare adverse events or long-term effects that may not have been captured in a clinical trial. While RWE lacks the randomization of a clinical trial and is susceptible to biases, advanced analytical methods can help mitigate these limitations.

The table below provides a clear comparison of the two data types.

Characteristic	Clinical Trial Data	Real-World Evidence (RWE)
Data Source	Protocol-driven collection at specialized research sites	Routine clinical practice, EHRs, claims, registries, wearables
Population	Homogeneous, with strict inclusion/exclusion criteria	Diverse, reflecting a wider range of comorbidities and demographics
Setting	Tightly controlled, ideal conditions	Routine care settings, hospitals, clinics, pharmacies
Outcomes	Prespecified outcomes over a limited timeframe	Broader outcomes, including patient-reported outcomes, over longer periods
Primary Use	Regulatory approval and establishing efficacy	Post-marketing surveillance, comparative effectiveness, and personalized medicine
Key Limitation	May not reflect real-world usage due to controlled conditions and limited sample size	Lacks randomization; prone to bias and confounding factors

Risk-Based Monitoring (RBM): A Strategic and Efficient Approach

Risk-Based Monitoring (RBM) is a strategic approach that moves away from the traditional, resource-intensive model of 100% Source Document Verification (SDV). Instead, RBM focuses on identifying, assessing, and mitigating the risks that could affect the quality or safety of a study. This is now the preferred method for regulatory agencies, including the FDA, as it leads to more efficient use of resources without compromising data quality or patient safety.

The RBM workflow, as outlined by the FDA, consists of three main steps:

Identify Critical Data and Processes: The sponsor must identify the elements of the study that are most important for patient safety and data integrity, such as informed consent, eligibility screening, and tracking of adverse events.
Perform a Risk Assessment: A formal risk assessment determines the potential sources of risk and the effect of study errors on those risks.
Develop a Monitoring Plan: The plan describes the monitoring methods and responsibilities, defining specific thresholds for risk indicators that guide the level of oversight for each site.

The central component of an RBM program is a centralized risk dashboard. All study data flows into this dashboard, which provides a visual overview of each study site’s status relative to its specific risk factors. The dashboard uses graphical and statistical tools, such as histograms and box plots, to spot outliers and flag high-risk sites. When a site shows a high-risk level, the monitoring plan dictates whether further investigation is appropriate, which may involve targeted on-site data verification. This targeted approach ensures that on-site investigation is the exception rather than the norm, leading to lower costs and more timely results.

The table below provides a framework for understanding the key elements of a Risk-Based Monitoring plan.

Element	Description	Application
Risk Assessment & Categorization Tool (RACT)	A tool for documenting risks, roles, and mitigation strategies.	Capturing components of an Integrated Quality Risk Management Plan (IQRMP).
Key Risk Indicators (KRIs)	Metrics that provide an early warning of potential issues within a trial.	Monitoring site-level metrics to identify unusual patterns or shifts in laboratory values.
Quality Tolerance Limits (QTLs)	Pre-defined thresholds for KRIs that trigger a documented investigation if exceeded.	If the query rate for a site exceeds a certain percentage, it signals a potential quality issue that requires attention.
Central Statistical Monitoring	The use of statistical algorithms and machine learning to analyze data for outliers and anomalies.	Automated algorithms quickly identify risk areas, providing immediate insight into trial performance.
Targeted SDV (TSDV)	The selective verification of critical data points rather than 100% of the data.	Patient data is assigned to pre-configured SDV regimens, focusing on critical-to-quality (CtQ) factors.

Automation and Artificial Intelligence (AI) in Clinical Data Management

The future of Clinical Data Management is inextricably linked with the rise of automation and Artificial Intelligence (AI). These technologies are not just theoretical concepts; they are already being implemented to enhance efficiency, quality, and compliance across various workflows.

Current applications of AI in CDM include:

Data Cleaning and Validation: AI algorithms and machine learning models can be used to automatically identify patterns in large datasets that may be overlooked by manual review. They can flag missing lab results or inconsistent identifiers, and even fill in missing values or remove duplicates.
Medical Coding Support: Natural Language Processing (NLP) is being explored to map free-text terms to standardized dictionaries like MedDRA or WHO-DD, streamlining the initial coding steps and improving consistency.
Query Management: AI can automate query generation by scanning data for anomalies and creating concise, plain-language queries, which reduces the manual workload on data managers.
Audit Trail Review: AI can analyze vast audit trail data to identify unusual patterns, such as after-hours data entry or irregular data entry behaviors at a specific site, which could signal potential fraud or data fabrication.
Risk-Based Monitoring (RBM): AI-driven RBM tools can adapt in real-time, focusing attention on sites where anomalies are most likely to impact data quality or participant safety.

The broader application of AI promises to transform the entire clinical trial landscape. By automating time-consuming and repetitive tasks, AI systems enable CDM teams to focus on higher-value activities, such as identifying safety signals earlier, optimizing protocols in real-time, and making more informed decisions. This transformation not only accelerates timelines but also enables more adaptive and responsive trials, ultimately reducing the risk and time to market for new therapies.

Tools, Challenges, and Career Trajectories

A Toolbox for the Modern CDM Professional

To effectively navigate the CDM landscape, a professional must be adept at using a variety of industry-standard tools and software.

EDC Systems: These are the primary software applications for data management in modern clinical trials. Leading commercial systems include Medidata Rave and Oracle Clinical. These systems are essential for handling the large volumes of data generated in multi-center trials. Open-source alternatives like OpenClinica are also available.
Statistical Software: Proficiency in statistical and data analysis software is highly valued. SAS (Statistical Analysis System) is a common tool for data cleaning, statistical analysis, and reporting in clinical research. SQL and R are also valuable skills for data manipulation and analysis.

Common Challenges and Practical Troubleshooting

Despite the advancements in technology, clinical data management still faces several common challenges that professionals must be prepared to troubleshoot.

Manual Data Entry and Inefficiency: The manual re-keying of data from sources like EHRs into EDC systems is a time-consuming and error-prone process. This can be mitigated through automated system integrations and robust data transfer agreements for non-CRF data.
Poor Data Quality: Missing, incomplete, or inconsistent data is a major frustration. The solution lies in implementing automated data validation checks, conducting continuous data review, and providing comprehensive training to site personnel.
Inadequate Planning: A lack of detailed planning and insufficient training are common pitfalls that can lead to chaos and inconsistency. A robust Data Management Plan (DMP) and thorough User Acceptance Testing (UAT) are the key solutions to this problem.

Best Practices for a Successful Career in CDM
