Enterprise Software Development: The Essence

Enterprise software development is a way for enterprises to increase operational efficiency and productivity with the help of secure, reliable business applications that are easy to maintain, integrate, scale, manage and are cost-effective with a lower cloud footprint.

  • Time: The end-to-end development of the first version of enterprise software or several essential enterprise software modules usually takes around a year. The exact timelines depend on the business domain it is used in and the composition and complexity of the required modules.
  • Key project steps: Discovery, enterprise software planning and design, UX and UI design, development and testing, data conversion and uploading, deployment, regulatory compliance assessment and certification procedures, iterative evolution.
  • Cost: $50,000–$500,000 for a standalone enterprise app, $1,500,000+ for a large-scale enterprise system. Use our free calculator to estimate the cost for your case. 
  • Team: A project manager, a business analyst, a System Architect, a regulatory consultant, UI and UX designers, a  database developer, front-end and back-end developers, QA and DevOps engineers.

Having 750+ skilled IT talents and vast experience in large-scale software engineering projects for Fortune 500 companies, ScienceSoft is ready to take over enterprise software delivery end to end – from planning to development to continuous support.

8 Steps to Enterprise Software Development

Below are described the typical steps we at ScienceSoft take to complete enterprise application development projects.

Step 1. Analyze enterprise needs and engineer requirements

Duration: 1–2 months

  • Documenting key business processes and how they’re covered with existing software, understanding the capabilities and limitations of the existing IT environment.
  • Eliciting business needs and concerns regarding the existing and desired business process flows.
  • Analyzing a broad business strategy (e.g., planned company growth and IT budgets) that can affect architectural and tech choices for planned software.
  • Drawing up high-level functional and technical requirements to software.
  • Evaluating risks of possible negative impact on business processes due to the introduction of the new system (e.g., lost productivity and downtime associated with transitioning to new digital processes, business user training).

Step 2. Plan and design the enterprise system

Duration: ~ 2 months.

  • Drawing up technical requirements for the new enterprise software.
  • Deciding on the architectural style of the new enterprise software system (mostly point-to-point/event-driven service-based or microservices) and developing its detailed design.

ScienceSoft's tip #1

Often, we see that it is more cost-efficient and less risky to re-use a part of our client's legacy enterprise systems than develop and implement new software modules and enable their communication with other enterprise systems. When we decide to re-use existing legacy modules in a new enterprise software development, we add to our project plan all or several of the following activities:

  • Reverse engineering of the legacy system (including all connections and interdependencies), interfaces between software components, data structure, and data design.
  • Code re-factoring to simplify conditionals, remove unneeded code parts, improve code structure, review complex or memory-intensive algorithms.
  • Adding new intuitive and integrated interfaces.
  • Designing and implementing the integration of the legacy modules with new software (see more info on software integration in Note 2).

ScienceSoft's tip #2

When integration with other enterprise or third-party software is required, we add to the plan:

  • Identifying integration touchpoints.
  • Choosing integration approaches (integrating via common data storage, mediated integration of SOA/microservices via message broker/ESB or PaaS, point-to-point integration, integration via UI/RPA, etc.) and technologies (e.g., for an ESB-based integration – Talend ESB and SAP PI, for iPaaS-based integration – Azure iPaaS or Informatica iPaaS).

ScienceSoft’s Senior Solution & Integration Architect

Non-invasive integration (integration via UI/RPA, data storage) is less flexible but also less costly and risky. Invasive integration (e.g., via implementation of SOA with re-usable functional modules that communicate via ESB) can improve enterprise agility and be cost-efficient in the long-term, but it’s expensive in the short term, architecturally risky, and may require quite deep preliminary code changes (very dangerous for legacy applications with their old, not well-documented code). At ScienceSoft, we prioritize non-invasive integration approaches when it comes to legacy software and, for more complex invasive integrations, always consider the adoption of the iterative integration approach to better control risks and prove architecture feasibility in the early iterations.

  • Enterprise application integration architecture design.
  • Planning how data should flow and whether it needs to be transformed into a different format.
  • Checking how many communication protocols between integrated applications will be used.
  • Designing additional security enhancements.
  • Preparing a comprehensive QA strategy to verify all uni- and bidirectional calls between the integrated systems, backup and recovery mechanisms, how well the integrated system works within established bandwidth limitations, etc.

Step 3. Design UX and UI for the enterprise app

Duration: 1–3 months.

  • UX designers and Business Analysts collaborate on UX research to understand the target audience and their needs, goals, and mental models.
  • UX designers describe how a user will interact with the system (identify digital touchpoints) and design information architecture.
  • UX designers create wireframes that demonstrate basic content layout and functionality.
  • We combine the wireframes into a prototype of the application and run prototype testing.
  • Once the prototypes pass user testing, UI designers transform them into full-color graphic interface mockups that are then handed over to front-end developers.

Step 4. Develop and test the enterprise solution

Duration: from ~ 6 months to several years (depending on software complexity).

  • Back-end development – building the server side and APIs of new enterprise software. It also includes integration with required business applications.
  • Front-end development – transforming static interface images provided by UI designers into a fully functional enterprise client side and ensuring its communication with the server.
  • Reviewing whether the system matches functionality, performance, security, and integration requirements. Testing usually runs in parallel with development.
  • Preparing training materials to help employees promptly learn how to use the new system.

ScienceSoft’s Head of Enterprise Application Development

Our clients often like the idea of shortening the time to release and optimizing the development budget by developing an MVP. It is a software version with only the essential features, which helps us test whether software meets the key stated user needs. Upon confirming or adjusting the initial EAS idea, we add other features to the MVP. We deliver the first working version of enterprise software of small to medium complexity in 4–8 months, with new functionality being added during major releases every 2–6 weeks.

Step 5. Prepare and migrate enterprise data

Duration: 3–6 weeks.

  • Inspecting the legacy data to migrate, avoiding duplicated or inconsistent data.
  • Deciding on the supported data formats and handling the required conversions if several data formats are in use.
  • Extracting, transforming, and loading the legacy data.
  • Conducting ETL testing to ensure data stays complete and adequately transformed (also, where feasible, developing and running automated ETL testing, e.g., using tools such as QuerySurge, Informatica DVO, ETL Validator)

Step 6. Deploy EAS to production

Duration: 1–2 weeks.

We deploy the enterprise solution and integrate it with the required corporate infrastructure. We first move complex software through staging and testing environments so that the team could spot all potential issues before release and safely introduce changes.

ScienceSoft's Head of PMO with 20+ years of experience

For complex projects we perform a trial implementation to minimize possible downtimes in production. The trial implementation is done for a limited number of users and requires comprehensive technical support in case any problems are encountered. Trial stages usually take up to 1–3 months.

Step 7. Ensure regulatory compliance

Duration: up to several months.

This stage is relevant for enterprise software or its parts falling under government or industry regulations, e.g., HIPAA, CGMP, GLBA, PCI DSS, GDPR. At this stage, our team compiles comprehensive documentation created during all stages – from software design to verification and validation – to prove that software and software development life cycle meet all essential requirements of a standard or a regulation.

Step 8. Evolve EAS in iterations

Duration of releases: 1–3–6 months (depends on a development and deployment strategy).

The development and delivery of new working software modules continue iteratively according to the following scheme:
