Compare And Contrast The Impact Of Using Hard Systems Method
Compare and contrast the impact of using “hard systems methodology’ (HSM) versus “soft systems methodology’ (SSM) on the areas relevant to the process of design and development of databases
This research paper requires you to compare and contrast the impact of using “hard systems methodology’ (HSM) versus “soft systems methodology’ (SSM) on the areas relevant to the process of design and development of databases. You need to investigate what SSM is as well as understand its underlying assumptions. An overview of HSM has been provided. Database design and development projects are often undertaken within process improvement and process engineering contexts, representing a critical component of an organization’s overall information systems development (ISD) efforts.
Information Systems Development (ISD) methodologies are collections of procedures, techniques, tools, and documentation aids used by IS developers to build information systems. Despite some common traits, these methodologies significantly differ in their concepts, methods, beliefs, values, and normative principles. The complexity of ISD processes is closely tied to the organizational environment's complexity. To manage this, IS developers create models of the future environment of the IS, which guide the design process. The choice of modeling approach depends on the underlying assumptions about the environment—ontological, epistemological, social, and representational—and influences the eventual design of the information system.
Different methodologies lead to divergent development paths and outcomes, meaning no two projects guided by different methodologies will produce identical IS models or processes. Functionalist methodologies—characterized by high complexity, formality, and structured diagrams—are prevalent and often favored for their maturity, popularity, and applicability to large-scale, complex projects. These “hard systems methodologies’ (HSM) reinforce an objectivist view of organizational data, emphasizing rational decision-making based on standards and technical techniques, where organizational goals are deemed objectively definable and measurable.
1. Main Differences between HSM and SSM assumptions
Hard Systems Methodology (HSM) and Soft Systems Methodology (SSM) are rooted in contrasting philosophical assumptions. HSM aligns with a positivist epistemology, assuming that organizational problems are well-defined and can be approached objectively through technical and rational means. HSM presupposes that the problem-situations are ascertainable with certainty and that appropriate, structured solutions can be developed using system analysis techniques. Its focus is on the design of optimal solutions based on clear requirements, emphasizing systems analysis, modeling, and mathematical formalism.
Conversely, SSM is grounded in interpretivist epistemology, recognizing that organizational problems are often ill-structured, complex, and subjective. SSM assumes multiple stakeholders with differing perspectives and aims to facilitate understanding and learning rather than definitive problem solving. It views organizational change as a process of social learning, where models and understanding evolve iteratively through dialogue among stakeholders.
a. HSM is preferable when the problem is well-structured, goals are clear, and technical solutions are sufficient to achieve objectives efficiently. Its systematic approach is effective in designing systems where precision and predictability are critical, such as in manufacturing or financial systems.
b. SSM is better suited when the problem is complex, ambiguous, or involves human and cultural considerations that cannot be easily formalized. In database development, SSM may be advantageous in capturing user perceptions, organizational politics, or ambiguous requirements that influence system design.
c. Both methodologies emphasize iterative processes, stakeholder involvement, and modeling, but their assumptions about the nature of the problem and the most appropriate solutions differ significantly, influencing their application contexts.
2. Impact of HSM and SSM differences on database development effort
a. Database Design
The differences in assumptions directly influence the design process. HSM's structured approach encourages detailed specifications of data requirements based on well-understood organizational needs, leading to comprehensive conceptual models like ER diagrams. This systematic approach streamlines the transformation of requirements into logical and physical data models, facilitating normalization and implementation.
In contrast, SSM promotes understanding stakeholder perspectives through iterative cycles, which may lead to more flexible and context-sensitive data models. However, this can introduce ambiguity and variability in defining data requirements, potentially impacting the clarity and consistency of database schemas.
b. Database Implementation
HSM's emphasis on formalization often results in straightforward implementation phases with well-defined specifications, reducing the risk of design flaws and ensuring smoother translation into physical databases. The detailed models derived from HSM support automation and coding.
SSM's emphasis on stakeholder involvement and interpretive understanding may complicate implementation, as data requirements could be more fluid and subjective, requiring additional validation and adaptation during the physical development phase.
3. Implications of HSM and SSM differences on information engineering process
a. Gathering of information requirements
HSM relies on systematic, analysis-driven methods to gather explicit, objective requirements, often through structured interviews, data collection, and formal modeling. It assumes that requirements can be explicitly defined and are relatively static.
SSM engages stakeholders directly in iterative dialogues, emphasizing understanding different worldviews and uncovering tacit knowledge. It recognizes that requirements are often evolving and subjective, requiring flexible, participative approaches.
b. Similarities between HSM and SSM
Both methodologies aim to improve organizational understanding, support decision-making, and facilitate system design. They involve modeling, stakeholder engagement, and iterative refinement to adapt to organizational needs and complexities.
4. Impact on data identification and acquisition from HSM vs. SSM
HSM’s precise and formal requirements gathering process facilitates efficient data identification, with clear specifications enabling straightforward data acquisition and integration. Its focus on technical accuracy minimizes ambiguity, supporting automation in data collection.
In contrast, SSM’s participative and interpretive approach may lead to broader, more context-aware data collection, capturing tacit knowledge and subjective insights. However, this can complicate data validation, consistency, and subsequent acquisition efforts.
5. Conversion of data into information and knowledge: HSM vs. SSM
a. Differences
HSM’s structured models promote systematic transformation of raw data into meaningful information via formal procedures, supporting clear pathways from data collection to analysis and knowledge creation. Its emphasis on accuracy and completeness ensures reliable decision support.
SSM’s iterative social learning process emphasizes understanding context and individual perspectives, leading to more nuanced and interpretive transformations of data into information and knowledge. Its flexibility allows adapting insights based on stakeholder feedback, fostering organizational learning.
b. Similarities
Both approaches recognize that converting data into useful information and knowledge requires context-aware analysis. They employ models—formal or interpretive—to facilitate understanding and decision-making.
c. Better approach
In my opinion, HSM captures the process more effectively in environments requiring precision, predictability, and automation. Its formal methods ensure consistency and reliability, critical for databases supporting operational or analytical functions. Nonetheless, combining HSM’s systematic techniques with SSM’s stakeholder engagement can provide comprehensive insights, especially in complex organizational contexts.
6. Differences in conceptual data models (e.g., ERD) from HSM vs. SSM
HSM’s emphasis on formal analysis and rigorous modeling typically results in well-structured, normalized ER diagrams aligned with entity-relationship principles, optimized for implementation. These models are often detailed and highly structured to support efficient database design.
SSM’s participative approach may produce more informal, stakeholder-driven models that reflect diverse perspectives and social realities. These models may be less normalized initially, requiring further refinement for implementation.
7. Easier conversion into logical/implementation models (e.g., normalized ERD)
Conceptual models derived from HSM are generally easier to convert into logical and physical models due to their formal structure and clarity. They often adhere to normalization principles, facilitating straightforward implementation.
Models from SSM may require additional formalization and normalization, as they may prioritize stakeholder perspectives over technical efficiency initially.
8. Information provided to decision makers via HSM vs. SSM
Databases built with HSM tend to generate precise, reliable, and consistent information, supporting operational efficiency, compliance, and strategic planning. The formal models enable decision-makers to trust data-driven insights.
In contrast, SSM-based systems emphasize contextual and interpretive insights, which can inform more holistic and adaptive decision-making. They may provide richer qualitative information but might lack the consistency required for some operational decisions.
